Node-RED  is a tool running in the Node. Flows can be then deployed to the runtime in a single-click. Domoticz supports a number of hardware devices natively rfxtrx, zwave, smartmeter etc. There are zillions of other devices out there, with a lot of interfaces. Domoticz can also respond to actions requested by anyone and passed on by the MQTT-broker.
Now something has to take care of creating and interpreting these messages. The Node-RED tool provides an alternative way to creating little programs flows to interface with anything you want. Or maybe you like to create programs in Node. So using Node-RED is not mandatory, it does however provide a fun and attractive way to handle messages. So it also depends on your needs and preferences.
It is highly recommended that if you are using Debian or Rasbian that you use the additional Mosquitto repositories. This will ensure you get the latest stable version of Mosquitto as determined by the project itself, rather than an outdated version via the Debian or Raspbian repositories. Instructions can be found here: . Then publish a temperature measurement to the virtual sensor idx noted above example idx 1 like:. Owntracks [owntracks. A Node-RED script could subscribe to the owntracks-topic and republish the info in a Domoticz compatible message so Domoticz can use the location info.
Note: If "command" is not set, it defaults to "udevice", the two following messages are equivalent:. Navigation menu Personal tools Log in.

Add SDS011 sensor with Tasmota to Domoticz
Apart from the omnipresent dark theme, the biggest update to the Tasmota firmware is the support fro ESP82xx based Zigbee devices! Tasmota 7. It basically works by listening for outputs from the devices on MQTT.
You have also mentioned, I believe, using a camera to monitor your system water pressure. Using brew on Mac: brew install esptool 1. Index number reprensenting the relay to control. My advise would be to remove it. The more devices you have with tasmota on the more standardized your smart home will become and the easier it will be to manage. But here is where it gets a bit screwy.
Adjust additional settings as needed. We need tell each Tasmota device that whenever the state of it's relay changes for whatever reason: button, timer, etc. Migrate to Tasmota 8. This plugin is to control ITead Sonoff devices that have been flashed with Sonoff-Tasmota via web calls.
It is designed on a principle similar to the Homie firmware.Ghiacciai o margherite: il cambiamento climatico e i contratti di
It should be easy to add support for others as well. Please enable it to continue. Perfect for testing Tasmota devices or simply controlling it via the mobile phone. What does work: Embedded broker is online and working.742 bobcat wiring diagram hd quality list
For multiple relay devices enter the index number that matches your desired relay. So the state of the device match up in Hubitat unless Hubitat queries the device. Documentation Site: For information on how to flash Tasmota, configure, use and expand it After you're up and running with Tasmota on your device go to Configuration - Configure Other When there: Paste the template string into the Template field Make sure you check Activate; Click on Save.
Currently it supports POW R2. Sonoff iFan I am writing a home automation program using Tasmota devices. Most of the parameters are self explanatory and have comments on a side that would help you determine what you should change. Using pip on Mac or Linux: pip install esptool; Download the latest Tasmota sonoff. Tasmota Logo Total local control with quick setup and updates. It specifies the button is a switch rather than an actual button.We had a situation in the city where people started to get sick with respiratory problems at the mass level and it was obvious that a major problem is the quality of the air.
I mean it was noticeable with the bare eyes and nouse but authorities kept saying that air is ok, and they were publishing fake results. Yes, it is ok if you ar an internal combustion engine with a great air intake filter!
This started happening with the beginning of a heating season, and it was just a coincidence that the city got a brand new heating plant. Well, later we find out that it was not exactly in city ownership. Moreover it is a privately owned and operated, with a nice and lucrative contract. In fact, the new plant is so nice that they shut down former plant with chimneys like two times higher than those at the new plant that was owned by the city and the only heating option left is this new monster that uses wood as a fuel.
I could write a completely new story on this subject, but I will stop here. I came to learn about it from the necessity. I wanted to see what is going on with the air pollution and I found a bunch of sensors there on the market but did not know where to start.
On the other hand, 0 — 50 is ok on their scale and that scale ends with On the other hand, you just have to put it on a good spot, connect it to Wi-Fi and power.

As soon as they started talking things like that, the air became so pure and enjoyable to breathe that everyone was so shocked and happy to have the opportunity to live under so wise rule. First, we will make a little bom bill of materials containing major parts.
After all, we are building a quite complex device. Therefore we must know what parts do we need. Regarding tools needed for the job, I used: soldering iron, hot glue gun, small drill, angle grinder, few screwdrivers, cutting pliers, multimeter, smartphone and a computer. Since I had to order some parts from China, there was not much to do until they came. I was killing some time wondering how to assemble everything together.
What will I use as housing? I went through some stuff I had and noticed the old HP Inkjet printer power supply.Last December Itead Studio updated their Home Automation product line with a new and different product. The main difference is that it doesn't have a relay and it's mainly sensors and no actuator if we don't define a notifying LED as an actuator. But, such a collection of sensors, with 3 of them having analog interfaces, cannot be run from the single-ADC ESP so Itead has thrown in a good old ATMegaP to drive the sensors and report the Espressif with the data.
The first thing that draw your attention about the Sonoff SC is it's casing. It's kind of a truncated hexagonal-ish pyramid with a round grid on top and a rounded bottom.
Seriously, somebody had a good time designing this. It looks a lot like a intricate speaker and actually that's what it is. Side by side with the fake audio hole there is an microUSB connector that's only for powering the device no data lines connected and a microSD slot. The microSD reader is connected to the ATMegaP and I'm not sure what original purpose it has but I can think on a couple of good things to do with it.
Once the 4 screws are removed it can still be a little tricky to take the PCB out from the enclosure since the button shaft leaves little room to lift the PCB from the plastic holders.
Meanwhile you try to remove it, take a look at the components on that bottom side of the PCB. There you can find the controllers and programming headers. There are a couple of simple, almost out-of-the-box, upgrades you can do to your Sonoff SC. Both sensors are pin compatible. Off course replacing the sensor is not the full story, you will need to add support for the DHT22 to the firmware.
More on this later on. You will need a GND connection too but there are quite a few available and properly labelled on the board already. So after making myself comfortable with the hardware of the device I started putting together some pieces grabbing code from other projects like the ESPurna firmware. That means no cloudthat means MQTT. The firmware is a good starting point but I don't like it's architectured. Everything is too coupled.
So first thing was to create a communications library between both microcontrollers. I started looking for similar solutions and found out the SerialComm library by fjctp. It was almost what I was looking for but I liked the AT commands approach, one char keys are too minimal and naming is important. So I wrote the SerialLink library that allows me to:. In the picture below you have a sample of the communication between both microcontrollers.
I will create it's own repo soon. In this code fragment you can see how message keys are matched and messages are forwarded to three different clients: MQTT, Domoticz and broadcasted to websocket clients like the web interface. Now, this is more like a game feature.Dkms linux gpib
Don't know if it's really useful but it's certainly fun to play with.This page lists almost all the devices and services that Domoticz can connect to. This list is curated by the community, so it may not be complete. Not all supported devices have pages on this wiki. In that case have a look in the Domoticz forum.
Please help grow this list. Also, have a look at the Scripts page, which also offers other ways of integrating hardware and services into domotics. Please add the name of the device or service, and if relevant, through which gateway-device you were able to connect to it. It would be great if you could create a wiki-page that explains the steps you took. Please refer to those pages if you think its reasonably safe to assume that the device will continue working with new versions of those gateways.
For example, it it works with bluetooth now, it will probably keep working in the future. If you have a device that is not supported you could lend it to the developers of Domoticz. Please provide us with either:. You can also open a topic on the forum to discuss about the product. If you are able to get a device working, please also share through which gateway you managed this, by adding it in brackets after the device name.

Banggood SKU Temperature sensor. See also the forum topic. If you want to include nodes with the Aeotec sticks, turn off the Pi before removing the stick. Also you sometimes need to be persistent when including a node fails for the first time.
Sometimes you need to try many times to include a node before it will work. Aeotec Minimote. Greenwave PowerNodes 1 and 6 socket version with power measurement, also known as Nuon Smart Plug 1 and 6. Temp sensor optional. To get the additional switches of Z-Wave Plus devices working you need to add the node in several groups. See the forum.
All Qubino dimmers can dim very low power LED lights without any bypass as they do not require a minimum load. This page will give you an overview of IP-cameras that users have reported working with Domoticz. A fast way to achieve this is to leave the 'Default gateway' field in the camera empty. By doing this it will only have access to your local LAN and no internet access.
Tenvis jptw - Image URL: snapshot. With this script you can grab snapshots from a RTSP-stream. It uses 'ffmpeg' to open the RTSP-stream and grab a snapshot from it. You still can't use it directly in Domoticz, but if you want to grab a snapshot when the doorbell is pressed for example, this script will do so outside of Domoticz. However, if you have a Synology NAS and have the cam working in the Surveillance Station packageyou can use this script.Wrf sst update
The conversion of the stream is done by the NAS. Pretty clever huh!? It cannot control devices directly. For every activity a switch device is added in Domoticz.Luckily, community took this issue in their hands, and over the course of year and a half, we saw 3 amazing OpenSource projects that are addressing this and many other issues. This post is an overview and introduction into different options, with a very high-level comparison between them.
Officially, project started in Januarybut it inherited a lot of assets from previous two incarnations, so we can say that project actually started as early as January As name suggests, it was originally built to replace stock firmware for early Iteads Sonoff devices, but it grew to a project that supports many more ESP based boards with a lot of sensors not originally found on Sonoff products.
Project is updated almost daily, exclusively by Theo himself, reworking some of the contributions from the developers community. This community is producing a lot of materials, including a lot of Youtube tutorials and very nice Wiki pages, contributing to adoption and success of Tasmota project. He apparently started with Wemos D1 Mini board being very generic and added support for many other fabricated boards, including Sonoff and others.
Xose is clearly an experienced software developer and a software architect, as project is very well organized and very well architected, but at the same time, is missing wider social adoption, despite very informative blog he runs. Project is updated few times a day, exclusively by Xose, based on the discussions or minor contributions by community. While there are few Espurna related videos on Youtube, they are far from coverage Tasmota got.
Technically, ESPEasy is the oldest alternative firmware out there. They started with generic ESP platform and added documentation on how it can be used for fabricated boards, such as Sonoff, which is clearly a hardware of choice for many Home IoT projects. Project is updated many times a day, mostly by few core developers from Lets Control It, but they also merge code from other contributors, which is quite nice and in the spirit of true OpenSource project.
All firmware options suffer from the same common set of issues and potential areas for improvement:. Community has build at least 3 good alternatives to vendor-provided firmware and each will satisfy most of the basic use-cases, such as controlling relays or signaling temperature reading using MQTT. Tasmota allows easy start and quick results, has powerful set of features and good support for different sensors, but also comes with some weird stuff that you just have to get used to. Apart from the standard method of flashing, community around Tasmota including yours truly offers a bit weird OTA method of flashing initial Tasmota image over the stock Sonoff firmware, without soldering or even opening some of the supported devices.
ESPurna might be lacking some of the fancy features Tasmota has, so your milage may vary. I personally found ESPEasy too unstructured and too loose for mass production aka daily usebut on the other hand, I love it when it comes to experiments with new hardware and new stuff, exactly because of the freedom and configurability it gives you.
It has very open but very powerful run-time configuration capabilities and is most advanced when it comes to local decision making, potentially reducing the need for MQTT broker and external automation logic.
In theory, all off the existing firmware options offer quite a good set of operability features, like Web UI, OTA, backup and restore, but I will dig into the usability in the next post, to explore how easy it is to really use this software on a daily basis and to rely on it for your home daily operations. Common functionality All 3 firmware options share some of the common properties: They are Open Source and built using Arduino frameworkand offer pre-compiled binaries.
They support almost all Itead Sonoff and quite a few other boards and modules, including all 1M Flash devices. All have a wide support for a lot of additional sensors and actuatorsincluding popular choices of I2C and 1-Wire sensors and power monitors.
ESPEasy takes it even step further with a lot of less usual stuff you would not consider as typical part of Home automation.
Some even offer specific topic layout tailored for easier integration with popular automation logic software, such as Home Assistant or Domoticz. They all support integration into Google Assistant and Amazon Alexa.
Documentation - being OpenSource projects, neither firmware has a well structured, properly designed and implemented set of documentation that would really make it easy for average user to get to quick results. Console is still accessed using browser and in some cases, is mandatory to set the device properly, which is also a negative point for this firmware.We had a situation in the city where people started to get sick with respiratory problems at the mass level and it was obvious that a major problem is the quality of the air.

I opened it and after measuring the size, it looked like everything could fit in nicely.
And it did, so this power supply casing was a box for my sensors device. First I put everything together to see how it works. I had a doubt regarding connecting two i2c sensors in parallel doubt was about addressing not about can it work or not. But it worked like the charm from the start. This sensor working voltage is 4. As always ground goes to ground. We already know about ground :.
Just to mention that it is not a bad idea to cover air inlet and outlet of a sensor while you work around it, especially drilling or grinding, to prevent dirt to pollute sensor. When all rough work is done, remove the covers.
