I’m new to this forum and energy monitoring. I’m absorbing a lot of new information, but I keep on hitting dead ends when trying to find the right hardware for my initial need.
I currently have a Bluetti AC200Max power station. I have two 200W solar panels feeding directly (DC power) into the AC200Max to charge its batteries. I then use the generated power at night to run things in my house and can use the AC200Max as a generator during power outages.
The AC200Max’s display shows real-time energy incoming from my solar panels, however, there’s no official way to export the data out of the AC200Max. What I’d like to do is be able to capture and record that incoming DC power data and feed it into Home Assistant.
I’ve gone down the rabbit hole of reading about ways to install custom integrations into Home Assistant and capture the Bluetti’s Bluetooth signal and pull the data out, but that would be a huge learning curve for me that I don’t want to undertake if I don’t have to.
I thought the OpenEnergyMonitor might be a perfect solution to this by using a CT around the wiring from my solar panels to the AC200Max, but it sounds like all CTs only measure AC, not DC.
I’ve also searched high and low for a “smart” inline DC power meter of some type where I could export the data to Home Assistant, but again, I can’t find anything for DC power. I can find plenty of DC power meters/monitors, but everything I’ve seen is just a dumb device and only displays real-time energy on its screen, which I can already do with the AC200Max.
So in summary, I’m asking for help on how to capture and retain DC power generation stats, optimally into Home Assistant. OpenEnergyMonitor initially looked like a perfect fit for me, but I don’t see any mention of the ability to measure DC power.
Thanks so much!
