What's your Next HA Project?

Like many on here, the more I read about this HA ‘addiction’, the more I come up with things I’d like to try. On my list, I have the following, think of it as a desderata:

  1. Recycle everything I can from my ADT SafeWatch Pro … many PIR sensors and doors/windows switches, then integrate in HA - a big learning curve at first glance
  2. Get WyzeCams to work with HA
  3. Put some automation to turn off lights if there is no one around. Wife and kids are notorious for leaving lights on. Or I could cut the power and give them one flash light each.

Just curious as to what else can be done … What are your upcoming projects/challenges?
