I think, this Shelly suports scripting. So why all this mqtt and node red? Switching on and off works by direct call from Domoticz like all older ones. And Shelly can send measured values ​​directly to Domoticz using a script running on it. For example here is a part of my code for sending amount of ...

Why so complicated when your 12V car battery can run ESP for maybe more than 100 years?

There is no easy way to get your format of serial data directly into Domoticz. If you are not a beginner with Arduino, program a module that will receive serial data from your module and send data via JSON API to Domotic via wifi. Or use mentioned Mysensor project. Or learn to write a script that ...

First - I see your address "/channels/1/pic..." and for me works "/channels/101/pic..." Second - Hikvision in manual recommends using strong passwords, but beware, you cannot use some characters in the http address. For example my own painful experience when testing stream with VLC. My password ...

Connect sensors to ESP running ESPeasy and you can calibrate each sensor individually before send data to Domoticz....

HA don't have any something like json api to send current state of P1 from Domoticz?

I prefer communication between devices. PIR detects movement and sends a command directly to light switch to temporarily turn on the light. The light switch knows that it has received a command from the PIR sensor and therefore turns on the light for a certain time. It also sends the information ...

You can easy build it yourself. I am using Sonoff Basic with 2 DS18B20 ( room and floor temp. ) running ESPeasy like standalone thermostat. Setpoint is received from Domoticz, heating status and energy consumption are exported to Domoticz. You can use Shelly1 too for that now. First version with ...

I think, you must build your own thermostat. All what you want can be done with Domoticz and ESPeasy rules for example. Here is my solution - not so complex. I don't need hysteresis, not using home/away - only timers for setpoint etc https://youtu.be/1ef6tRinOQ4 Third winter without any problem ....

I use Setpoint timer feature for sending scheduled value to my ESP thermostat:

1) backup database from Domoticz web page 3) Shutdown your RPI 4) remove its SD card and in another computer copy /home/domoticz folder 5) install new system and Domoticz 6) copy specific files to /home /domoticz new instaled ( scripts, images, floorplans - new versions do some of this by backup ...

ad 1) I have one Sonoff with ESPeasy and with "service IP adress" If some thermostat fails, I replace it with this "service" Sonoff, connect to its "service IP adress" and load config file previously stored for specific thermostat. This will restore everything including working IP. Or you can do ...

My solution....
Floor heating independent thermostat with Domoticz setup.

My "offline" thermostat works 3rd winter without any problem. Not Tasmota but ESPeasy with "rules". ESPeasy holds temperature ( room or floor ) and sends heating status, temeperatures, energy consumption and number of relay actions to Domoticz. And make some "safety" - check max allowed floor ...

And why script for this "switch custom message", when you can write notification directly in switch notification tab?

Hardware setup?
For example Sonoff Basic.
Code for Domoticz and ESPeasy rules are in my post.

I am using separate selector switch for similar case. I use one setpoint and selector switch decisions if I regulate room air temperature or concrete floor temperature. I your DzVents script you can divide program execution according actual selector state. I think for the specific room is quite ...
