Are your switches with RF capabilities? Such switches sometimes react when other devices communicating in the 433MHz band are operating nearby. This frequency is not protected and the protocol used is fixed-code and not unique. There is no easy way to avoid this.
As I sad, i also have wall switches with the same behavior, so more then one. I think is hard to belive that we have the same hardware isue! Mine are both Smartwise type. Also with 3.7.3 FW, also with the same message in the log list ‘device button pressed’. I had to delete them from my net. I think little more analysis it would be better.
I have numerous WiFi switches and relays at home (FW 3.7.0). All are voice-controlled with Alexa. None is affected. Some time ago, I experienced problems with one of the RF-R2’s but it was related to unidentified RF signal that triggered uncontrolled switching on, mostly at night. The solution was to relocate the switch.
The device I was referring to was Sonoff RF-R2. Apart from WiFi, it can be controlled with RF on 433.92MHz frequency band (on/off). The problem was with RF signal and not with WiFi. So don’t move your walls
I assure you that I will not move the walls. It’s interesting that the message in the log list is ‘device button pressed’ as somebody pressed all the two buttons at once, I refer to my two channel wall switch. And I’m sure 100% that’s not that case.
