What is this daylight savings thing of which you all speak? Oh, I live in Arizona, that's why - one of the two enlightened states where we don't do such silly things. :⁠-⁠)

This is an interesting topic. I've been thinking about building a hot tub heater control for mine with an ESP32, a high voltage/high current DPDT relay, plus a couple Dallas 1-wire temp sensors. I'm already using ESPHome and Home Assistant for various DIY controls and monitoring. While this...

I'd be fine with getting paid a wholesale rate by my utility - but they pay me only a flat rate yet force me into a time of use plan for what I buy from them. And they raise rates every year while lowering what they pay for what I send back to the grid. Fair is fair, but the utilities aren't...

While Arizona is indeed great from an irradiance perspective, it's a terrible solar market since our ACC (the government entity that regulates utilities) is very much anti-solar. Setting up for off-grid/100% self-consumption will be the only viable path soon, in my opinion, with export rider...

Heh, we typically find things that are three or more years old in ours when we get around to cleaning it. Dry climate here, so frost isn't much of an issue, so we are lax at cleaning it out. It'll be fine, right? Hmm, well don't want to risk it, so we'll just put it back in the freezer until...

That's normal - and a result of using self-signed certificates, so nothing is wrong, it's just an annoyance to click through.

I believe I had a similar issue with my Delta MAX, which fried itself with "50hz/overload" on the display the day after I got it (I'm in the US with 60hz grid). My plan was to use the MAX as a battery/buffer during outages, running critical loads with it while charging via DC from solar and/or...

I have a grid tied only system with a SB7.7US-40 (2019 vintage). It's a very solid inverter. Optitrak/Shade Fix works pretty darn well, better than I expected, as long as only a small portion of the string is shaded. No requirement for the rapid shut down nonsense here, so no additional module...

I have the smaller Delta Max, which I bought for the same purpose. It's already been RMAd once. I wish I had built a DYI solution instead. Having said that, it does work as long as it works.

I have several Kasa plugs, mostly controlled via Home Assistant automation, and have found them to be stable and reliable - some like my DHW circulator are turned on+off several dozen times throughout the day.
