Tuya Smartlife integration stopped working

I have been using HA on a Raspberry Pi 4B for some time to control devices under Tuya Smartlife, but this morning none of the devices will turn on or off from the webhooks.

I checked and they will not turn on or off directly from Home Assistant.

Things I have tried:

  • Rebooted Pi
  • Updated the HA Host System to HassOS 4.10
  • Removed the Tuya integration
  • Added the Tuya Integration. Note this found all the devices, so clearly HA can still talk to Smartlife but still cannot turn devices on or off

Has the Tuya Smartlife intergation stopped working? I installed Home Assistant because I knew Tuya were turning off the IFTTT integration, so I wonder if something else has also been turned off that has stopped them working with HA?

Are there any logs I can check for error messages - not sure how to access these?

Thanks
