Reading GJ usage from UH50

Having been able to enjoy being part of this community for a week, I thought it was time to give something back :smile:.

Before I moved to HA, my Pi was running a Python-script to read the GJ-usage from my Landis+Gyr UH50 device. Now that my Pi is running the HA-image, I needed another solution. I’ve found Appdaemon to be very useful for that.

The script is based on this discussion (in Dutch): Hoe log ik telegrammen van een Landis+Gyr T550 UH50 stadsver - Duurzame energie en installaties - GoT

I haven’t had the time yet to do the most obvious part and store the results in HA itself :joy:. For now I just send the results to a local API (for further processing).

I have no idea if anyone is interested at all, but if so, you can find the code here: GitHub - vpathuis/ha-extract-warmte-uh50: Appdaemon app for extracting the usage of warmth from the Landis Gyr UH50 device
I’m not a coder by profession, and I’m sure there are many improvements to be made, feel free to make suggestions. If you’re going to use this, you’ll first need a IR Converter Cable.

Update: this is now available as an integration: Landis+Gyr Heat Meter - Home Assistant

I’ve made some progress on this part. It’s now an integration: Landis+Gyr Heat Meter - Home Assistant
The Appdeamon solution is therefore no longer neccessary.

Hi,

is there a good possibility to read the UH50 with a tasmota powered IR reader, like this one?

I’m fairly new to home assistant, but my heat meter is too far to read it by USB.

Sorry for reviving this old thread.

Best regards
Samuel

I’m not sure. Not all usb cables work either. If you give it a try, please let us know!

I don’t think so, as your mentioned combination with Tasmota presents data send via MQTT and the current build-in integration (above) is expecting a ‘direct’ read via USB cable.
So, can you get the Hichi build be able to connect by WiFi to HA?? I don’t think so.
Myself, I have been using the Hichi with Tasmota and Mosquito MQTT on HA but you have to do all the work in HA (sensor, templates, etc. ) yourself.
