New Zigbee Zemismart / Tuya Light Smart Switches TS0004 and TS0003 switch on and off as a group in Home Assistant - Physical buttons work fine

Hello everyone,

I have been using Zha in HA for a while and have more than 10 smart switches. Recently, I have bought new Zemismart/Tuya Zigbee Light Switches (TS0004 and TS0003). Unlike my previous ones, each one of these new ones are switching on and off as group when I use the entities in Home Assistant. If I press the physical buttons on the switch, they do work well, and they turn on and off just the one I pressed. If I try to turn on or off just one button via Home Assistant, all the buttons on that switch will also turn on or off.

I have same-model switches that work fine here, but they were bought about year ago. I suspect it has something to do with their firmware, but I am not familiar nor confortable with tweaking the internal working of the switches.

Has anyone come accross the sama problem and or could help me?

Thanks a lot.

Hello,
Have you found a solution for this? Using a ZHA quirk worked for my TS0004 but not for my TS0003.
Please let me know if you found a workaround.
Thanks, Airton

I did. Opened an issue and the good folks there provided me with a solution. Hope it all goes well for you too.

Got same issue with TS0013 (by _TZ3000_snq47izk) which I recently purchased. Used to have TS0003 which they worked well
