Unbricking Wyze Contact Sensor - pcb reset pin

[muerte33]

I was perusing an old thread and came across a post by a Wyze employee about resetting a door sensor.

Forgotten Sensors (dead batteries)

Hi all! I’m very sorry for the inconvenience. We looked into the sensor issue as our top priority. If your sensors are not working after battery replacement, please try these steps, Take out the battery Wait for 20 seconds while the battery is taken out. Put in the new battery. If the sensor’s status light flashes once, you are ready to go! If your sensor’s status light does not flash, repeat Step 2, or use the pin to push the sensor reset button 3 times (make sure the battery is taken out). …

It worked on one of my problem ones, so I thought it might be worth a try for you folks:

The interesting trick was pushing the reset button 3 times while the battery was removed?

Well I did get one to pair, but then it did not work properly (open and close with magnet), so I deleted it and never could add it back. Oh well.
No matter what I do after replacing the battery it blinks twice.
