Also there is a problem with getting status of device. Device name is MK601. It has cb2s module (see attached photo). Protocol version of device is 3.4.

surprised it was working previously, from the TO-DO list in the readme: "Support devices that use Tuya protocol v.3.4" Would assume that's the issue?

Suppose it can be the reason. I've just tried to use that integration with my devices. I have almost the same four tuya devices and one of them works in localtuya but others have problem with adding in home assistant with error "Failed to get status". When I try to found differences using logging I see that one device give a reply with protocol version 3.3 and three others have 3.4 version.

tinytuya 1.7.1 already supports 3.4. protocol
