8 months ago ~Additional info: I have only been able to trigger this issue when a load is connected to the device. With load connected, it typically triggers within minutes of power-cycle.~
~If no load is connected (ie unplug the lightbulb) the device works correctly as far as I can tell.~
Edit: forget it, I just triggered it without load, although it took a little longer (a couple of hours). As before, only power cycle restores it.
This is unlikely to be entirely a hardware problem, given that the devices are widely sold at Costco and presumably work well with the Tuya app. Also some users are reporting that ESPHome does not suffer from this issue.

PROBLEM DESCRIPTION
I have the Feit Electric Smart Dimmer. As noted in some other forums, users have observed issues with the TuyaMCU communication breaking down intermittently.
The result is that remote control of the dimmer (via web interface) does not work. State changes are reflected in the web UI, but the physical device is not affected. However I can make manual changes to the device, both switch on/off and dimmer control, and those changes are reflected in the web UI. It appears as if the TuyaMCU commands can be received but are not transmitted to the MCU. There are no TuyaMCU heartbeat responses.
It is often possible to restore functionality by a power cycle (not just rebooting), but it tends to break again quickly. I have tested this with 2 different devices, with same results.
