Smart heating with Mill Power-up

Updated over a week ago

Connect your Mill devices to Tibber, get insights and control your devices smarter.
For general and basic information regarding radiators have a look at this article .

If you haven’t noticed we now have two Mill Power-ups available in the Tibber app. Which one to use should depend on a few things. Read on…

Mill 1.0

This is the “old” power-up. This one talks with their old API. This one should only be used by generation-1 devices from Mill, even if you’re running their latest app-version.
The only real change here, is the name of the Power-up.

By connecting your device to this power-up you’ll get access to insights regarding your individual heating devices from Mill. You’ll also be able to utilize our functionality for vacation mode, smart heating, and day- and night savings. More on that topic here.

Mill 2.0

This is our new power-up. We created this one to be able to talk with all the gen2 and gen3 devices that have been upgraded with the latest firmware from Mill.
You do this by updating their app to at least version for iOS and/or version for Android, and then follow the instructions in there. I.e. this Power-up can only be used with generation 2 and generation 3 devices that has gone through the above steps. But it has some neat functionality that our old integration doesn’t have.

If you're uncertain, you can check what generation your device is part of, by looking at the serial number. If it starts with SKAG, it’s a generation 1 device.

The new functionality:

In the new Mill app, you have the option of grouping your devices into different rooms. What is important to consider is how this will affect and look in the Tibber app.

  • If your radiators are not connected to a room or if they are connected to a room but are set to be controlled individually, each individual radiator will be added as a "thermostat bubble" in the Tibber app.

  • If they are connected to a room but not set to be controlled individually, the room will be represented as a "thermostat bubble" in the Tibber app instead. This applies to all radiators that are not set to be controlled individually.

When the target temperature is changed via Tibber, any preset "mode" will be changed in the Mill app, to "Comfort mode". It has to do with limited possibilities for us to control against other modes.

We now also support Mill Sense. It will appear as two "sensor bubbles" - one for humidity and one for temperature.

Depending on how it is set up, it will also affect the temperature displayed in the "thermostat bubble" for your rooms and/or individual devices.
The temperature displayed there, without a Mill Sense is always the average for the room (if grouped into rooms) or the actual measured temperature for the individual radiator. However, if you have a Mill Sense connected to the room, its temperature will be displayed there instead.

If you change something in the Mill app (e.g. move your radiatiors between rooms, etc) you need to do a "re-pairing" in the Tibber app for the update to take effect in the Tibber app. I.e. you need to go to the Power-ups tab and disconnect your Mill devices, and reconnect them again.

PS. As soon as smart heating, or holiday mode is activated in the Tibber app, a Tibber logo will appear in the Mill app to show that we are now in control of how the radiators run.

Get up and running with your new Mill device

You first need to install your radiator according to the instructions from Mill. Please refer to their manual and/or support if you need help.

Then you need to connect it to their app, this can be tricky sometimes so here are a few tips and tricks:

  • The devices should be connected directly to the router through 2.4Ghz Wifi, mode b/g/n.

  • Bluetooth is necessary to have activated on your phone.

  • Minimum OS version: iOS 8.0 or Android 5.0.

When done, make sure you’ve set up everything in the Mill app, and that it works from within that app.

Now you can move over to the Tibber app, find your power-up, press connect to Tibber and follow the instructions from there, and you’re good to go. You’ll find the related icons on your home screen in the Tibber app.
