Support for Smart Plugs has been a great addition to Sensing & analyzing specific devices within my “noisy” home. Now I’m adding a HPWH and I’d really like to have a smart plug that works for 220v appliances so I can get a good handle on it’s usage within the Sense app. There’s been discussion about this topic in other threads, and I apologize if the answer is elsewhere, but I couldn’t find the latest & greatest recommendation.
In “LG Refrigerator never detected” @oshawapilot described how he’s done it with a regular 110V smart plug, but politely declined to provide a wiring diagram and I’m pretty hesitant to short two 220V legs together.
But I’d be more inclined to try some special wiring through TWO of the smart plugs, one for each leg… has anyone tried this? Or are there any commercial 220V products available yet that could work with Sense? Or any specific suggestions from Sense?
