Windows Sensors - Besides the Wyze bundle, what Options are out there?

This topic seems to come up now and then … so confusing is the landscape out there. Luckily not as many people make and sell windows sensors as those that make smart plugs.

Yes, I did a google/amazon search and there are many options, and that makes it difficult to pick something reliable/compatible/affordable/(put your own requirement here)

In any event, I have few Wyze installed (old generation), and contemplating getting the new ones. Granted they are not available for individual purchase, and one to commit to a year of monitoring, which might make financial sense. Any thoughts/experience with those?

  1. How easy to interface with HA ?
  2. Any special hardware required ?
  3. Currently running HA on RPI4, would that be compatible ?
  4. Are the other components in the Wyze bundle useful/interfacable with HA ?
  5. Anything else?
