Looks like the days of 433mhz sensors in my home are limited.
Today I purchased 8 more Ikea Motion sensors, not quite going all in, but close.
These were relatively cheap at $9.99 each.
I got them all set up today, slowly deploying them throughout the home.
Should be able to work on the software portion of replacing my older 433mhz stuff.
Back on treadmill again.
