Why the heck is this PR still not merged?
It works flawlessly for me, it’s just annoying to have to add manually this quirk.
I have this TRV but i dont see attribute 5010 (0x1392) for cluster: 6470. So this settings does not work for me. 
Did you apply the custom quirk from the PR? Did you unpair and re-pair the TRV?
I’ve created custom_components\zhaquirks\xiaomi\aqara folder, then i copied the file thermostat_agl001.py from zha-device-handlers/zhaquirks/xiaomi/aqara/thermostat_agl001.py at 7f30c58c1d1ce5e4348fad491e8ef991177403ae · zigpy/zha-device-handlers · GitHub
Then i restarted HA and “reconfigure” my zigbee ZHA device but nothing has changed.
The correct path for thermostat_agl001.py is ./zha_quirks
When you fix the path, you must delete the thermostat from Home Assistant entirely, and readd it.
What do you see in the device information?
It should say “Quirk: thermostat_agl001.AGL001” like in this screenshot
Did you enable custom quirks in configuration.yaml?

Thank You. This is what I was missing.
I know necroposting and stuff. But I though I’d share the blueprint I made for the Aqara TRV based on the quirk from the PR, so people don’t have to go on the same journey I had to: Aqara E1 thermostat external temperature sensor by mb1248 · Pull Request #2802 · zigpy/zha-device-handlers · GitHub
This Blueprint takes the following inputs:
- Takes an Aqara TRV (ZHA)
- A temperature sensor
- (Cluster Id)
…and triggers:
- upon sensor change
(only when on) - every 30 minutes
(I thought since the thing is battery based, maybe don’t spam it every minute when it’s not actually doing anything) - when turning on the heating
…doing the following:
- set thermostat to use external sensor
- update value of external sensor based on provided sensor value
There was no good guide on how to setup an automation for this, so I figured it out based on some Github comments and created a blueprint that abstracts almost everything, so you only have to provide the device and a temperature sensor.
