High temperature reading

Hello,

i would like to use smart implant as high temp zigbee sensor, anyone has got an idea which converer from K-type thermocouple to use? I found MAX6675, but it has SPI output...

 

Thank you, Vitek

SmartImplant talks Z-wave, unfortunately not ZigBee.
The easiest and cheapest solution is to connect a MAX6675 module to an ESP32 or ESP8266. ESP communicates with WiFi which is faster and more stable than ZigBee.
If the HC3 can communicate WiFi (or MQTT) with the ESP modules, you will then have to write code to send and receive data.

 

If you want to make it really easy for yourself, you can install HomeAssistant on a Raspberry.

HomeAssistant includes ESPHome that communicates with the ESP modules and there are ready-made examples of how to configure and communicate with e.g.. MAX6675 module.

The code below is all that is needed to get data out of the MAX6675 from HA.

Thank you for that info

I have Homey Pro which has Zigbee and MQTT as well, so it does not matter which one i will use I'll have to figure out how to reag out data in Homey
