Looking for Local Sauna Controller

Hi All,

We’re getting a sauna installed soon and I’m looking for a HA compatible sauna controller. But for the life of me, I can’t find a cloudless solution. Either it’s dumb, or it works via cloud (arghh, classic).

e.g. I’m loving the looks and functionality of the Huum UKU Wifi, but it needs cloud connection and doesn’t provide local control options. It goes a bit far for me to build my own controller, so I was hoping I’m overlooking a certain brand controller that does give me local connectivity.

Thanks in advance!

ps. Sauna get’s a 3-phase powered 9kw over (with each phase 230V and hence <16A)
