A couple years ago MidAmerican energy sent me a free Powerley smart(ish) thermostat, gateway (z-wave, I think), and wireless meter adapter as part of some pilot program. Apparently the customer data they acquired by hosting the cloud platform for it wasn’t worthwhile, because they’ve now canceled the whole project and shut down the cloud service/app that controlled it. They’ve generously said I could keep the whole kit, but it’s basically be a dumb thermostat since it has a very minimal interface, all programming was done through the app.
Where should I go from here? I’ve asked Powerley if there’s another app I can use to interface with the gateway/thermostat even if it’s just locally, but I haven’t heard anything from them in the last couple months and that seems like a long shot anyway. I’d prefer to run a local service so I’m not subject to subscription fees, privacy issues, and the cloud provider just shutting down. My wife and kids like using Alexa and the Google personal assistant, so compatibility with them would be nice, but not needed. The Powerly system didn’t integrate with Google or Alexa. Our heat is currently a standard propane forced air furnace, which is functionally pretty simple, but I’d like to add a heat pump to the system and make it dual fuel. In a perfect world I’d be able to program current fuel costs into the thermostat so that it could choose to heat with the cheapest fuel.
The Hubitat gateway says that it’s compatible with the Powerley thermostat. I like that it’s not cloud based, but $130 seems like a lot for what looks like a box with an RPi in it. Does anybody have any experience with Hubitat good or bad?
I could buy another smartish thermostat like a CT1000, but that wouldn’t really get me anywhere, I’d still need some server like OpenHAB to control it, and I don’t have a machine I want to leave running in the house 24/7.
I’m leaning towards something like HestiaPi as I can buy the kit and RPi for about $90, print my own case, use a memory card I’ve already got, and use it as the central, always on server for future smart house devices. My house doesn’t have a C wire even though it’s only about 13 years old, so I may need to run off an adapter or something. Any experiences, good or bad, with Hestia?
