Ways to cut the cost
- 1
Use wireless sensor systems — sensors run on batteries years vs wired constant draw
Cuts wired-sensor system draw 50-70%
- 2
Replace old hard-wired panels — 90s/2000s panels draw 15-25W
Saves 90-150 kWh/year
- 3
Consolidate with smart home hub if possible
Reduces total always-on device count
