Is somebody working on a integration between homey and heatpumps of Stiebel-eltron?
Since begin of 2023 i have one and I would love to be able to set basic settings automatically by flows.and follow some essential values like temperature of water, heating etc
I have already separate app but it’s really great if i can add it in homey. last missing integration.

I’d be very interested in this as well, since the ISG WEB supports the SG Ready (smart grid ready) function!
This allows me to let the heat pump heat up my boiler when I have over production of my solar panels.
For this to work, I need Homey to control the SG Ready function of my heat pump. Unfortunately I am no developer myself, so I hope someone could help me/us with this functionality.

Yes same here, thinking about buying a ISG web but need to be able to integrate it with homey to get the best off it.

Hi @H_van_Barneveld,
Did you manage to get your Stiebel Eltron heatpump connected to Homey? If you did, I’m truly interested in how you did it and if I could replicate it myself, or if you could, maybe make it an Homey app for everyone to enjoy?
Hello Jelmer,
I have created my own app. Using it a few weeks now and it seems to work ( for me )
Have to find out how to publish it. Beside that way to support is a question to. I’am not a developer.

That’s great to hear! I’d love to experiment with it myself. Unfortunately I’m not a developer either, so I’m sorry I cannot be of help for the support part. Maybe publishing the app might inspire someone that is.
Ben er zeer benieuwd naar. 
Hi @Jelmer_Knuivers ,
I use two of the four switches in this 4ch-Smart switch
to send the two SG_Ready signals to ISG Web. So I send one, when I have spare PV electricity and one, when it is relatively warm during the day ( to get more efficiency). Unfortunately it does not help very much.
There should be a possibility to get/set the data via ISG WEB’s web-site servicewelt which is done in HomeAssistant, as I found in the net. But I am far away from knowing how to implement that for homey.
Hi everyone, I bought my homey just this week and am also interested on how to integrate my Tecalor / Stiebel-Eltron heatpump into my smart automation. Looking forward to see if there is a way. Best regards, Sebastian

official release will follow if it’s reviewed succesfully

You’re a hero! I installed it following your instructions and it works! I’ll test it in the following days and will keep you updated.
There is an updated version available, this to solve issues that block approve of Athom.
I’m already very grateful for your effort to share the app with us!
I don’t know if this is the best place to provide you with some feedback, or that you would like to open your own [APP] topic for it, but here is some anyway:
- I don’t seem to receive all values from my heatpump. As you can see in the attached screenshot, I mis the ‘Kamer temperatuur’ value for instance.
Other values that I haven’t received yet are ‘Dauwpunt’, ‘bron pomp’ and ‘Circulation pomp’. But these might be dependant on the heating, which I currently do not use in summer? - The ‘WP retour temp’ field is showing a value for which I think the decimals are not correct.
- I’m keen to learn more about what the different values show, so I can think of ways how to use them. Is there some description of these somewhere?
- I’m very interested in the use cases and flows you (or the community) already have created! Maybe we can share these somewhere?
Hi Jelmer,
If i’am right dutch?? maybe you can provide your emailadres?
