Incompatible with bluetooth proxy

[aheath70]

I have been running this for a while and it has been working flawlessly.

On my ESP that gets Emerald data to HA, I also pick up bluetooth from a couple of Xiaomi temperature sensors. That works well as well.

I am in the process of converting over to use the HA Bluetooth Proxy functionality. I have converted 2 other ESP's to bluetooth proxies and that is working too. When I add the bluetooth_proxy: declaration and attempt to upload, I get the following:-

If I remove the bluetooth_proxy: line, I can then upload the code successfully. If I comment out the Emerald components and sensors, I can also upload the code successfully.

I suspect that there is a conflict between bluetooth proxy and the Emerald component.

Did you get anywhere with this? I'm about to add this to my bluetooth proxy ESP.

[aheath70]

Didn’t get anywhere with it. Ended up configuring up an additional ESP32, so had one running Bluetooth proxy and another running the Emerald code. I retired this component about 4 months ago as I have moved into an apartment and the meter is in the basement and I am in the 3rd floor so not possible to get the signal between the two. I also don’t have access to the meter.

I didnt want to run another ethernet run for a second POE esp32 over in the same corner so I asked copilot to convert the implementation to work as a regular homeassistant integration.

I present to you https://github.com/splitice/homeassistant-emerald-ble . All credit really goes to WeekendWarrior1 since thats who built the reference implementation.
