In the Tapo app I set up a smart action whereas when the T100 registers a motion it switches two Tapo smart bulbs on or off depending on their current state. It generally works as intended (the smart action being: When "Motion detected" > Then "Turn On/Off" the bulbs). The T100's detection interval is set to 60.

The problem is, after a few days the bulbs fail to switch on according to the same smart action, i.e. they just light up for less than a second and that's all. This is the second time happening with this kind of automation.

Is there anything that I should check?
