Use HTTP request for fetching data from Kamstrup 401 #51

Did you read the instructions?

[X] I have read the README.

The request

I now use a ESP8266 to get data from Kamstrup401. With a URL i can fetch data from the ESP8266. The IR reader is connected to the ESP8266 Example : http://192.168.0.207/energy The response is: {"energy [GJ]" : 371.383,"power [kW]" : 0.0,"flow [l/h]" : 0,"water [m3]" : 27509.55,"tempin" : 29.48,"tempout" : 22.59,"tempdiff" : 6.89} So it would be nice if this also can be used.

This is out of scope.

If you use an ESP to read the values from your meter, why not publish them to MQTT and let Home Assistant get them from there? Or when using ESPHome, you can publish the values directly into Home Assistant. In both these suggestions you can use push mechanisms instead of fetch, which is IMO always preferred.

Or perhaps you can use the rest integration for this.

Can you share the code for esp8266? I have multical 603 and would like esp to publish data into MQTT. Also the ir sensor is diy?

Could you create a repo at your github and we could talk about it there? It might also be possible to do a direct esphome version for usage in home assistant like home assistant glow.

Can you also share the ESP8266 code with me? I am in a similar situation where the meter is nowhere near the RPi
