2 of my Tapo P100 smart plugs have stopped properly working.

Both are set up and running since 22-Aug-25.

Tapo #1 has a set up schedule to switch on sunrise/ off sunset and hasn't failed switching on and off on time.

Tapo #2 has a set schedule to turn on every hour. Then there is an automation flag that is set up as so:

WHEN: Tapo turns ON

THEN:

1. Delay 5 minutes

2. Switch off

3. Send Notification

Since December 19 for BOTH

Tapo 1: does not switch on/off on the set sunrise/sunset time intermittently. Sometimes it is still on well after the sun has set. Sometimes it doesnt switch on / is late. It was already such a hassle that I had them set on schedule for a fixed time in the morning and at night. It still has the same behavior - not switching on (observed 3x now). It switches off delayed, like 30 minutes after set time (20:00)

Tapo 2: has only ran the automation once or twice a day since 19 December. I had only noticed while trying to figure out Tapo 1. This was real disheartening as the Tapo controls 4 vivarium's humidity (connected to an analog fan controller) and is supposed to run 5 mins every hour. Since 19-Dec it has ran 23h and 5 minutes a day 😒

I had observed my WAPs, and there is no interruption (ran a ping test during this time on the local AP via a wireless device + google [for checking internet access] there were no spikes in latency locally, nor anything out of the average / dropped packets internet wise.

Did anything change? Why are my devices suddenly unreliable?
