- Matter Controller: Hompod Mini v18.3 (22K557)

- Both S220's have the issues intermittently, the S210 doesn't and neither does the T100.

- What happens is, we remove the Tapo bridge in homekit, readd and put the S220 into two seperate rooms. We then have a left and right swtich in each room. The Left switch is wired up to control the light whereas the right switch is left unwired to act as a trigger for lamps in the room. We then setup automations for both rooms such as When right switch on turn on X Y Z lamp. Time goes by from a day to a week. We will either notice that the left switch is missing in one of the rooms or that the right switch is missing, this is normaly found out when one of us presses the right switch and none of the lamps turn on in the room. We check the homekit app and can then see one of the switches is missing. Sometimes it's only the left or right switch, sometimes it's both.
