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)
I have the same question. @EntireSpeckled did you find a solution? @all: Any suggestions for a sauna control with local API?
In the end it is trivial:
It is a 2point control switching three phases based on a temperature sensor and has a door-contact and a passive (i.e. not controlled by a microcontroller) overheat protection.
Sorry, I missed your reply. I ended up building my own controller. Based on a esp32 s2 super mini with ESPHOME and a lot of other electrical components. Mainly based on the layout of this guy: killee: sauna controller
I added extra safeties but then again, I’m an engineer but not electrically certified so I’m hesitant to publish my electrical circuit structure and code. If you pm me I’ll gladly help you out a bit and also share my code.
