Wyze sensor v1, is a POC, it's THE WORSE contact sensor that can be purchased

[SlabSlayer]

My understanding is that the critical fault is in the sensor chipset sourced from TI. When the battery voltage drops to a very low critical level or completely runs out before changing it causes the lockup in the chipset logic because of the low voltage reading logged.

So long as the battery is replaced before that critical low voltage is registered by the chipset, the sensor will continue to operate.

There is a really great post by @carverofchoice that includes a screenshot explaining the chipset fault:

Beware updates

The only timed obsolescence I could possibly see someone claiming is the V1 contact sensor locking up when the battery dies. Wyze did not create this problem, it was the chip maker, Texas Instruments as I recall. They specifically mentioned it was a weakness of the chipset they created, and it can technically be fixed, though it too complicated for most people: [image] That again, wasn’t Wyze being greedy, in fact Wyze worked to make push notifications and other things to help prevent that Te…
