I have a neo coolcam pir v2 in use, and the battery is empty.

After replacing the battery how do I connect it to homey again?

It is the first time a sensor ran out of battery with me.

It is blinking 1 slow and 5 quick at the moment

Looks like the battery I tried was (almost) empty. I got some red led flashes from the sensor so I assumed it was full.

Trying another battery the sensor connected in 5sec with homey again.

So the answer is, just replace the battery, no special actions needed. 😛
