I had issues with my tap switch, it would stop working. Here are my notes from the disassembly.

Internally a PTM215Z.

Join (or re-join) procedure

This sometimes is required even if nothing changed, not sure why.

Set the hub to scan for sensors (POST api/${user}/sensors) - This could be optional if the channel was changed. Try skipping this first, if that doesn't work, retry without skipping this.
Press and hold button for your channel (see table below) for at least 7 seconds.
