Interesting. Technotherm does use the same Smart Box controller. I didn’t have much luck with trying to figure out the Smart Box controller itself, because it is not installed at my location. I did have success with Haverland’s API though. I could not find any web based link to Technotherm’s API. It seems that is only possible through their app. Now that their are two rather large companies using the same piece of hardware (the Smart Box controller) it might be possible for someone far more talented and experienced than I to figure out the protocol it uses to communicate with the heaters and write a component that does not rely on the API.
Technotherm manual lists the url of the web app. While the interface is identical to Haverland they are using their own API. You can log in via the web and use apps like Request Maker or Postman to figure out the url of the API. My guess is that its structure and function are similar or identical to Haverland’s.
Thanks for the update, that all sounds promising. I was able to find the API URL with wireshark, It uses the same domain as haverland but with a different host
http://api-lhz.helki.com/
I was able to compile the Haverland client but not sure how to use it.
I tried some curl commands but couldn’t seems to get it working
curl -X POST \
-d '{ "username":"XXXXXXXXXXXX", "password":"XXXXXXXXXXXX", "grant_type": "password" }'\
-H "Content-Type: application/x-www-form-urlencoded" \
-H 'Accept: application/json' \
-H "Authorization: Basic NTU3OTM4OWJlMzc3ZWQyOTBiMGQ1NTNlOlVMREI2NjRz" \

I’ll try some of the apps you mentioned and see if I can get more info
Cool! Bit late in the day in my neck of the woods, but I will post my experience with the Haverland API in the clear light of tomorrow, but as a heads up: Haveland’s API root url is at https://api-haverland.helki.com. Helki seems to be the key.
I really like how your integration looks. I have been playing around with it some more today and I was able to POST to the app and update my radiators. I now know that the controls are possible
curl -X POST \
-d '{"mode":"manual","stemp":"17.0","units":"C"}' \
-H "Content-Type: application/json" \
-H 'Accept: application/json, text/plain, */*' \
-H "Authorization: Bearer xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" \

I’d be interested to see how you integrated it with HA
Bingo! That’s identical to the Haverland API. Good news that two seemingly large European manufacturers of electric radiators have adopted identical tech for smart electric radiators. I ended up running a python script on a RP outside of HA that interfaces the API with HA MQTT climate component and MQTT switches and sensors. It is a crude approach, but it does work. I know that it is possible to create a component based on an API something like this. But I lack the time (and talent) to pursue it at the moment. I will try and post my humble python script to github in the next day or two. I have been super happy with my heaters and now that it seems like the Smart Box tech is being more widely adopted it might be practical for someone to create a component for “official” integration with HA.
Excellent stuff! My coding knowledge is horrendous, but I will help out where I can. I can hopefully draft in a coder friend of mine to help out.
I’m looking forward to seeing the script!
Found another manufacturer who has adopter the tech: HJM. Seems the tech is becoming more widely adopted.
I came across a few more in my searching. Had you looked at trying to communicate with the radiators with RFLink? It would require additional hardware
I was planning on experimenting with the Smart Box itself while I had it in my hands, but got swamped with a bunch of “life” stuff. Then had to head back to my current location, which is many thousands of kilometers from the heaters, so when things slowed down enough to mess with it, the only practical option was through the API. My guess is that the Smart Box is just an RF blaster of some sort. If it is, it should be possible to use my trusty Broadlink RMs to use HA to learn the codes and control the radiators directly. It also might be that the Smart Box communicates with the radiators via another protocol. Just have no way of knowing until I am “back in the saddle again”.
Hey guys you might want to try this custom component …maybe it works
Hmmm… The Cozy system is quite similar to the Smart Box system in that it relies on a bridge to communicate between the app (API) and the heaters. Much nicer looking bridge though. I can see from the client that the API endpoints are different, though similar in structure. Won’t work “out of the box”, but no doubt that this could be adapted for use as a custom component for the Smart Box system. Good news: smart electric radiators have arrived (in Europe at least) and are here to stay.
Thought about it overnight and my experience with RF and IR is that it is “one way” communication. The radiators are sending data back to the bridge so it seems that some different protocol is at play. The Cosy Touch appears to be running on somfy io-homecontrol, so given the similarities, perhaps Smart Box works this way?
Thanks for sharing. I’m going to try deploying over the weekend
I found 2 more companies with the same Smartbox

Aside from the intriguing tech, the makers of Smart Box seem to have a cool business model: they don’t make smart things, but rather make things smart for an industry that seems to be made up of many small companies manufacturing great products. Very clever. Good luck with the script!
Hi all,
Any update? I’m very interesting in this integration.
Thanks in advance!
I have spent some time at this but I’m really not a coder. I’ll try and make some headway over the Christmas break
Hi everyone,
I have a similar radiator that is produced by Haverland to a big retail chain (AKI / Leroy Merlin) which they brand it as Equation.
I had 4 older models at home that work very well with a normal smart plug just to turn on and off (since it keeps the last state) but one just stopped working under worranty and they gave me the new model that doesn’t work well with the smart plug (since it simple loses the configuration). I didn’t want to spend money in the smartbox just because of one heater… so like mentioned here in the forum there must be a way that radiator comunicate with the smartbox… if we can intercept then there is no need for smartbox.
Anyone has any ideia?
The rads communicate with the smartbox on 868mhz. You would need some sort of hardware to read/write from HA to the rads. I had looked at RFLink but they don’t specifically mention these radiators on their device compatibility list.
It looks like it is possible to use the radiators with a Deltadore box and integrate this into HA. I don’t have the hardware so can’t confirm.
