thermocouple temp measure

[Raxis777]

Hello i'm using thermocouple type K in my project to measure temperature of engine. Is there a possibility to add it to domoticz? i'm using op amp and ADC mcp3008 which gives me voltage value? If there isn't any option to do that maybe it can be done with MAX6675 ADC or any different ADC? Thanks for help

Connect the mcp3008 to the GPIO pins of a raspberry Pi running Domoticz.

Using the ‘sysgpio’ hardware module you should be able to read the values coming from the mcp3008.

Else you can connect it to an esp8266 or similar. Mysensors.org also has a Domoticz integration.

I was able to do this, but if i add GPIO with my voltage value it treats it like a lighting source not temperature and shows that is closed and not generate any data. I can't modify it unfortunately. Can you tell me what's wrong ? I want to me it a temp source and showing data in Celsius value.

I would prefer to not to buy more stuff because it already has cost me pretty much. I want to find a way to read it straight from ADC or something like that. I see that there is many positions in hardware but not sure which one i should choose to read this data and i wonder if it can read converted voltage which is supposed to be temperature as temp in domoticz

By the way I would like to ask if I connect the microcontroller to another WIFI network will my configured domoticz work? I'm wondering about this because sometimes on the same network I'm using after switching on the microcontroller domoticz goes offline and I have to reset it from the terminal.
