Hello Home Assistant Community,
This is my first time posting for support, so please bear with me if I miss any crucial information.
I’m experiencing an issue with one of my Zigbee dimmers after updating to Home Assistant Core 2025.4.4. The dimmer is a TS0601, manufactured by _TZE200_vm1gyrso. It’s connected via a Texas Instruments CC2652 coordinator using the built-in ZHA integration.
Here’s some information about the device from Home Assistant:
Device info TS0601 by _TZE200_vm1gyrso Connected via Texas Instruments CC2652 Firmware: 0x00000040 Zigbee info IEEE: a4:c1:38:81:be:e0:d9:5f Nwk: 0x161a Device Type: Router LQI: 57 RSSI: Unknown Last seen: 2025-05-01T17:29:45 Power source: Mains Quirk: zhaquirks.tuya.ts0601_dimmer.TuyaTripleSwitchDimmerGP
The Problem:
Since updating to Home Assistant Core 2025.4.4, I can no longer control this specific dimmer from within Home Assistant. Specifically:
- I cannot turn the dimmer on or off using the Lovelace interface or through automations.
- I cannot change the brightness level using the slider in Lovelace.
Crucially, I’ve noticed that if I manually operate the dimmer (using its physical buttons), the status and brightness level are correctly reflected in Home Assistant. This indicates that the communication from the device to Home Assistant is working, but the control from Home Assistant to the device is not.
I have already tried restarting the Home Assistant server.
Could anyone offer some guidance on how to troubleshoot this issue? Any help would be greatly appreciated.
Thank you in advance!
