Switch outlets with $1.80 switches. Yank out pretty lights and put in simple cheap hanger cans. Keep your dumb honeywell thermostat and reinstall the 4 wires. Buy dumb smoke alarms and litter them everywhere (they're cheap). Yank out special outlets and put in el-cheapo outlets.
In other words, yank out and substitute the smart stuff back to cheap dumb stuff that just works.
This isn't hard. It's a few hours to do this swap. And most of the mains stuff can be picked up at Walmart or similar for cheap.
