Hi!
I’ve got an Tylö Helo Elite Sauna controller. That one is about 2 years old now - and is already integrated in my WLAN & can be controlled by an app on my eg. iPhone. Looking for an integration in HA! Anyone an idea? The most interesting thing would be turn on/off and maybe temperature…
Annoying thing: Tylö released recently an “Elite Cloud” version which supports control over the internet. I guess nearly no change in the hardware, just some software add-on for the cloud connection but can’t find any upgrade/update for my slightly older controller.
Same issue here. I have also emailed to Tylö support in Sweden, but no response.
They have their own protocol which is wrapped in a TLS connection. So it is difficult to find out. And there is no documentation on their site.
I guess if Tylö doesn’t support here someone with good network & reverse-engineering skills has to take a look at such setup - decrypt or track the communication between the Elite Cloud controller and the heating unit itself. Since it’s all on the LAN it should somehow be possible. Unfortunately I’m not the person who can do so.
I don’t think I have the possibility to crack their encryption to their cloud infrastructure, but I haven’t really looked into it yet. I just assume it’s a strong, well implemented encryption.
But it really sucks to be stuck with a cloud-only solution! Last year there was a major ransomware issue at their cloud provider. This made the remote stuff totally unusable.
Not a big deal - my sauna is in my garage next to my house, but I would rather have a local integration to the controller from my Home Assistant.
I don’t think my “Elite” controller has any cloud connection. There is a newer version of the Elite one with Cloud stuff… my slightly older one I guess not: The app on my iPhone connects through the LAN directly to the Elite control panel afaik.
No idea how this is done on other versions of the controller.
I didn’t know they had a version without the cloud connection, my bad.
I will continue to try to get some feedback from the developers of the Tylö app.
I used to party a lot with the tech people in Halmstad (where Tylö is developed) at the time. I hope someone will pick up my request.
Yes… before they release the “Control Panel Elite Cloud” there was another “Control Panel Elite” which looks exactly the same but this one has no cloud stuff, just WLAN connection: It just broadcasts into the LAN and a mobile phone with the Tylö App can discover the Elite control panel and then control it (a bit). Not 100% the same features then the control panel but you can turn it on and off and the major stuff. Works OK in the LAN (sometimes loses connection between Elite & phone, not 100% stable) and I was even able to use it via VPN’ing into my Home LAN for remote activation.
But - in general - of course it’d be nicer to integrate that into HA
The Cloud connection is somewhat unstable as well, this is the reason I would like to talk to it using a local API in the controller.
I generally don’t like the cloud connected stuff in HA, but somtimes there is no other option.
I started this project a few years ago and it has since evolved into a combination of various efforts and countless hours spent analyzing signals with a logic analyzer.
The system is primarily designed for Pure models but should also be compatible with Combi and Elite (olea) models.
I am now looking for testers! All you need is an ESP32-S3 connected to the bus using an RS485-to-UART board. The total hardware cost is under 20€.
The power is provided directly through the oven’s bus. (12V / GND / A+ / B-) - → 12V → 5V step-down for the ESP and using the onboard LDO (3V3) to power the UART (MAX485S) transiver.
