Local Tuya v4.1.1

Using Tuya App Yes

Light still works perfect through the cloud based Tuya App both in Home Assistant on on Mobile device.

Also having the same issue, seems you can only configure a light once and if it ever needs to be added again it will not work.

Will this ever get looked at? The longer we wait, the more updates that come out,

Now running HA 2022.11 Problem still the same

[DravenSA]

So, with sheer frustration I fixed it.

I removed the light from the SmartLife app (Tuya), and deleted all data pertaining to it,

I then added the light again, (it failed a few times, but i eventually got there) I then noticed it had a new Device id, (so that was good news) I went through the process to get the Local Key (this was also different from the old one) Once back into Home assistant added a new device through Local Tuya.

All back up and running now. Bit of a pest, but this worked for me.

I have also had this happen occasionally when re-adding devices. Worst case was to delete the device from LocalTuya, go back to tuya website and check the local key. OK, i probably did a reset on the device while trying to reconnect.

If device has been reset the Local Key will change, and (quite reasonably) LocalTuya will not connect to it using the old local key. Using the new Local Key works without any problem.

Thinks, maybe the wording of the error message should be changed to something like "Unable to connect to device with this local key. Please check and try again" ?
