I’m getting started with energy tracking and for most of my loads it’s pretty straight-forward using a combination of Shelly plugs and PM1s. However, I have a sauna that I would like to also track the consumption of, and it is a 3phase 400v system. I have been unable to find equipment which can take that voltage. I was looking into the Shelly EM3, but while it would work in terms of amps, it is also rated 230v.
Does anyone know of hardware that can take a 400v load and measure its energy consumption?
