I got this cheap Zigbee temperature sensor from Amazon, and I managed to get it working with a modified quirk, so I’m sharing my info on it here.
Huacaoe TYZGTH1CH-B1RF
I discovered that with my Home Assistant ZHA setup, I could only control the switch function, but not get the temperature information. It didn’t quite work with the TS000F_TZ3218_7fiyo3kv.py quirk that was recommended for it, but with some help from AI, I managed to get it working. So I’m just sharing it here in case it’s helpful for someone. I haven’t taken the time to understand exactly how it works, so I’m mostly trusting the AI on this one, but it seems to work well. For general info on how to install a quirk, see Add a how-to guide for how end-users can use a custom quirk in ZHA by Hedda · Pull Request #2419 · zigpy/zha-device-handlers · GitHub.
