Hi Smarthus1,
The Mill Heating Homey app was primarily built to integrate Mill devices with Homey while keeping any setting modifications in the official Mill app.
So, to answer your question: yes, it can be done, but only if there is a compelling reason for it.
What issue would this solve for you?
Are there others who would benefit from adding this feature, and if so, how?
Best regards,
Ivelin
Thanks for quick reply. I would like to use Homey for all settings and donāt need other apps. As far as I can see this setting is the only one missing.
I am having trouble adding the Mill WiFi Gen 3 to Homey. I am able to install the app, but I canāt add the heater. The heaters are connected to the network through the Mill app on my phone.
Hi Paul,
The Gen3 WiFi devices are supported and should work as long as you have configured the App credentials.
Have you configured your Mill app credentials in Mill Heating app?
Which driver are you using: Mill or Millv2?
Mill driver is connecting to the Cloud and controlling the heaters via the Cloud-based API.
Millv2 is used for direct local management via the deviceās own API.
Best regards,
Ivelin
My Gen3 invisible models worked with v2 drivers (local). Remember adding credentials in app settings (More ā Apps ā Mill Heating).
Proposal:
Can we get a āAndā card for when Mill Sense Air triggers the TVOC alarm? I use the tag in a logic card to trigger when it is over a certain value, as a work around.
Also contact mail is wrong.
Send me a message if you need assistance with the app (dev/ops).
Hello,
Can you help me,
I canāt switch on the heater in the homey app
In the Mill app is the switch off and if a these switch to on the it works the homey app fine.
But if i switch off the heater by Homey (works well) then goes the heater off. and canāt after that never switch on.
Mill Wifi max 1500W
Homey Pro 2023
Thanks
Hi Philip,
Iāve added TVOC condition to the Test version of the app.
Can you verify that it works for you?
Best regards,
Ivelin
Hi Rene,
Have you managed to resolve this issue?
In case is still present, please provide some more information.
Ivelin
In the debug console I have a lot of messages about "Error setting control source to open_api.
In the Mill app, all the devices (gen 3) are in their respective rooms, and I@m pretty sure they are on local control.

Hello, Ivelin, The app runs locally on homey. I only have 1 heater and it is listed as an independent in the Mill app. Strange is that it can turn off in the homey app but no longer turn it on. So I have to turn it on in the Mill app
Thanks for the great support.
Hi Rene,
Please, try removing the device and adding it as a Millv2 device, then select Cloud API.
See if that will work first. Then you can try adding the device as Millv2, local integration.
Have you been running firmware upgrade on the device recently? You can delete and add it in the Mill app to do so.
Are you aware which generation this oven is Gen2 or Gen3?
Maybe try opening the URL http://IP_address_of_the_oven/ and make a screenshot of the information there.
Since I donāt have this device available, I can only guess what the issue can be.
Best regards,
Ivelin
Thank you for quick response! Seems to be working great 
nicely done
Thanks for the feeback
Memory usage has fluctuated only between 62 and 78mb, so no memory leak.
Units are all on a fixed IP address (for a long time already)
Homey itself has no memory or resource constraints, also at this point I restart homey already almost every dayā¦
Heaters are connected, but what might be happening is that they lose wifi connection (connection is not super stable at home). unfortunately, after a heater has lost wifi, or f.i. had a restart then it wonāt automatically reconnect to homey it seems.
Hi Patrick,
Great! Now, I would suggest that you check if the heaters are running latest firmware version first. Then try improving the
WiFi coverage for at least one of them and see if that will help.
Have a great one!
Best regards,
Ivelin
Just set up my Gen3 Oilfilled heater as a v.2 unit after having had some problems using the cloud API. Very nice and responsive now! I gave it a fixed IP address in the router as well.
BUT - have you considered adding a card for controlling the power? There are three stages: high/medium/low. Iām honestly not sure what the benefit of going below High would be as long as one controls the thermostat - but it might make sense to turn it down when the outside temperature isānt to cold.
Hi Roger,
Great to hear that v2 and local API works well for you!
Since I donāt have that device available, it will require some network magic to get hold of an API endpoint that I can play with.
If you find the API endpoint and parameters I can try implementing it, but for me it doesnāt seem to be a very practical feature.
Let me know if you still see the need for it.
Best regards,
Ivelin
Hi Ivelin. I was about to add a new Mill device and to my surprise thereās now an official app from Mill. I tried searching this forum for mentions about the official app, but couldnāt find any.
I still added my new oil oven to your app, but I am keen to know if you are aware of any key differences between Official and yours at the moment? Is this the only app that allows local API for instance? I know you have taken over the app after Jesper, and I see you are quick to respondā¦I guess Iām also wondering if your interest of keeping this project alive has changed since thereās now an official app?
Hello Magnar,
Mill has finally released its own official Homey app, which is entirely cloud-based (for the time being).
The current difference between the two apps is that Mill Heating is focused on local integration, but bear in mind that Matter support has just been released, which Iām very much looking forward to be testing.
My plan is to keep the project going as long as there are more than 100 active users. Currently, there are close to 3,800 installations and over 5,000 devices.
At the same time, I would like to encourage everyone to start playing with the official app and help Millās software development team align the appās features with our needs.
Cheers! 
Ivelin
P.S. If anyone has any information about Jesper, please contact me! Iām unable reach him on any of his social media accounts or e/mail.
I also see the need for this. I have a mill oil wifi in the basement stairs. It needs to be turned on all the time. Depending on how cold it is outside it never reaches the temperature setpoint anyway. Hard to explain, but as I want to run local api due to Mills server issues the original mill app wonāt be able to toggle between power modes.
Also it would be nice in case the overall power usage of the house is about to exceed the tariff limit to adjust down the power usage instead of just turning the unit off or adjust the temperature down.
So it would be really nice if you could implement this into your app
