KS220M dying out of nowhere
KS220M dying out of nowhere
I have the exact same issue as described in this previous post:
https://community.tp-link.com/en/smart-home/forum/topic/641150
I'm disappointed to see that there was no answer resolving the issue from 2 years ago.
I currently have several KS220M installed in three bathrooms in my house. Everything works for a while, but then they just stops working (never all at the same time. When this happens, it's like the affected dimmer's hardware has crashed. Even the physical buttons do nothing, Nothing works. ie. If I attempt to trigger it using the motion sensor, the physical button, or the app and the light doesn't change states (sometimes it is stuck off, other times it is stuck on). It continues to look online in the app.
When I press the restart button on the right, bellow the main switch, the switch reboots and works again for a while.
This is happening often enough that I may have to remove them. 🙁
Has anyone else had this same issue and found a fix?

@jbc7 Beta firmware has been sent to your device. You may check it later in your Kasa app and perform the update.

I upgraded my 4 switches to the beta firmware you sent me through the app. Three of my problematic switches had the same issue as always today. I walked in the room and the light did not turn on. Pressing the switch does nothing. It functions again after pushing the restart button.

I installed the beta firmware on my switch. It is still numbered 1.1.6.
It was ok for a 3 days, but froze today.
I am curious, the others who have the problem, do you have Home Assistant or some other home automation device polling the status switch on the local network?
Another possibility is a capacitor that is starting to fail.

I am running home assistant. I have automations set up around the three that crashed most recently. Are you saying that you believe this is likely the cause of the ones that are crashing?

Following this. I just got one of these installed (KS220M), running firmware 1.1.6 and using homebridge plugin. Will see if this constant polling causes the switch to crash.
Other switches and plugs I have (KS225, HS210, KP12M) all seem to be working perfectly.

I don't think home assistant as such is the problem, but it could be a factor.
It is not The Problem because other Kasa devices work fine.
It might play a role since the communication with HA is by polling, as opposed to push for the cloud connection. Polling means more cpu activity, more heat and more chances for something to go wrong, both physically and in software.
Push updates for HA, that must be somewhere high up on everyone's wish lists, but not as high as switches not crashing:)

@ValentinMTL I can pretty much confirm it has to do with homebridge (or whatever 3rd party service). I had it on and it crashed within hours, had to restart switch.
I turned off "3rd party services" in the Kasa app which weirdly enough ONLY causes this switch to stop working with the homebridge plugin I'm using and the switch has been stable.
So not sure what it is but something in the firmware or this switch for some reason is clearly different.
