One consideration is a smart plug (with sufficient amperage) and energy monitoring capability. Example (there are others): HS-110.
- Limitation: Normal household current (US 120 V)
- Amperage: 15 amp max per HS-110
- Hubitat Integration: "[RELEASE] TP-Link Plug, Switch, and Bulb integration"
- Special Setup: In preferences select one minute refresh interval.
- Accuracy is average 30 seconds and maximum of 1 minute (based on refresh interval).
This plug only solution usually works for washers and electric dryers. In US, that is normal US wall plugs but NOT the 220 V plugs used for all-electric dryers.
