Mill has some server problems.

The Mill app will probably not work when you see the errors in HA.

The error handling will be improve from HA 0.84

I ssee you are also the author of the Tibber component and in pyTibber the future energy price is implemented. As far as I understand future energy price is not implemented in HASS is due to this https://github.com/home-assistant/architecture/issues/15
Is there a way to get around this and perhaps make a custom component as a weather entity?

Thanks

You can modify my custom component for it: https://github.com/Danielhiversen/home-assistant_config/blob/master/custom_components/tibber_prices.py

Thanks for sharing!

@Danielhiversen

Thanks for doing the Mill code!
Do I understand correctly that the HA Mill component communicates with a Mill server for it to work.
Or are the panel heaters locally controlled?

If not locally controlled, any chance to make this work?

18

It connects to the Mill servers.
I am sure it is possible to control it locally

Thanks for replying.

Emailed Adax and some other producers and it looks like Mill is the only one, maybe publishing their API. Just a shame we can’t select to control the heaters locally. What happens if your WLAN goes down….

20

Yes, local access is preferable for many reasons: https://blog.roysolberg.com/2019/01/mill-heat.
I have been in contact with Adax, and they are working on an API. But I think it also will be cloud based.

21

I had a brief conversation with Mill via mail about 3. party integration, and they’re currently working on getting IFTTT up and running. I would hope that means local control?

22

How is this integration ment to be used? When setting the temperature with HA the programs in the app no longer work. Setting the temperature in HA seems very unreliable, for example my HA thermostat is always saying target temperature 23C - regardless what I set it to. If I change it the heater reflects this change but the target temperature in HA goes back to 23 soon after, preventing me from actually setting it back to 23C without calling the service manually.

The thermostat component shows “heating” constantly even when it’s not.

Also, curious why my heater has a “fan mode” displayed? It’s the AB-H1500WIFI so obviously no fan, but it does have 3 power modes that I can’t control from HA.

23

After some time I got access to the API that MILL made. But this is only for controlling their devices through their servers.
The same will be with all other intergrations. Going through their servers.

So since I did not want to be depending on internet and that their servers were working I opened the heater and started looking.

I found a chip that could be programmed, but having been down that road before without any success I chose not to do that.

I checked a bit more and found some headers that gave me 3.3VDC and one pin that I could control the relay.

So a small esp-01, changing the temperature sensors (since I don’t have a ADC on the esp-01) and some wires (no soldering). I now have full control over my heater. And if it breaks, I can just connect everything back and still have full waranty.

And with my knowledge it won’t be able to cause any more risk that the oven can start a fire. (There were no internal control in the chip telling the oven to turn off)
I also added in the firmware that if room temperature is hotter than 28degrees celcius it would turn off.

24

I would like to see if this works as well.
I have a Telenor 4G as WAN failover. Whenever the network switches to the 4G, Mill (even with the app) stops to work. I guess Telenor blocked some proxy/websocket that are used by Mill.

25

If you do what I did you have full control and can implement how you want with Home Assistant. No need to go online.

26

Do you have a sketch or code to share? Thanks

27

Will try to make something during the weekend. But it might depend on the model. I will post what I have.

I have created a guide on how I did it. Hope it can help. And please give feedback on improvements.

Is there a way to use the Mill component with another sensor? I have the heater below a window and it reports lower temperature than what’s in the rest of the room.

Hi, I have a sun room which is partly insulated (not fully insulated for winter time).
I want to install Mill infrared heaters.

I see that there is two types with remote, wifi and Bluetooth.

As I understand the @Danielhiversen 's custom component is based on the wifi type.
(I also assume that the wifi controller on the infrared heater is the same as on the panel heaters this thread is about).

I’m quite new to HA and this might be a stupid question: is it possible to control the bluetooth type of heater from HA or should I go for the wifi type?

31

Hi there.

Are there any news about local control with Mill heaters? Or, if I may ask, as you seem to be also the developer, with Adax heaters? I want to buy some new heaters shortly, and I’d prefer to have them controlled locally.

Many thanks and best regards, Luís

No news for local control with Mill. But should be possible to modify the hardware: [Guide]Millheat hardware modification, making it open source

Adax will release local control, but not sure when.
