Yagusmart WiFi wall switch fails to configure in local Tuya

[AndySymons]

It works fine with cloud Tuya and I have integrated other switches of the same type into local Tuya, so this may be a local issue - but how do I track it down?

When I configure this device in Local tuya it detects 3.3 automatically, but gives the message "An unknown error occurred. See log for details."

This error originated from a custom integration.
