power consumption not exact (but a mere reflection of the max ) #19

Using 3 Mill gen 3 heaters in the App, set to local only. Had to select 1500 or 2000w and then install finalized.

Next, have the Home Assistant integration import these local heaters, which went fine.

My question (or bug, not sure yet): the Home assistant integration creates an entity for current_power consumption. However, this is always showing either 1500 or 2000, but as it turns out, that is not the power usage of the heater at all. my 2000 watts devices use 1840 or so, when I measure that with my calibration plugs.

So, is this not a true power sensor, in the sense it actually measure its power, and as such not very useful. its either 0 when off, 2000 when on.

or, is it a bug, and should this be looked into.

if the former, we can bring that across to the Home assistant dev. if the latter please do ;-)

Strange! My sensor "Current power" for my Mill devices displays really detailed power consumption in Home Assistant.

Mariusthvdb commented 11 months ago

thx. are you using local only too? or maybe the cloud connection? tbh, its quite impossible to synchronize the app and the Ha integration with the device currently. it even makes the power sensor not respond at all when I fact heating..

wonder how your reading can be though, as the heater is either on or off, and doesn't modulate?

I am using the "local" connection in Home Assistant. I set this up this simple way:

Add the heater to the Mill app, but without adding the heater to a room.
Entering the IP address in Home Assistant, adding the heater(s) as local devices.

A couple of caveats:

The Mill integration in Home Assistant will probably not support the mode "Off" until version 2023.10.
Some of my heaters had operation mode set as "Independent device", and some were "Control individually". For some reason, only "Control individually" works correctly in Home Assistant (on "Independent device" the set temperature does not stick). I changed the operation mode using the REST API documented in this repo.

How odd. I have them setup exactly like that . Still don't understand your heaters modulate and not simply are on/off however.

About the control : currently it's really unpredictable which mode of operation works best. The app or Ha. If I control via the app I see the set temp not stick often.

And even when ( I just noticed they were set at 27 degrees C), they don't trigger the heater ... which was a bit of luck ;-)

We only get the control individually when you assign the device to room. I don't use rooms anymore ( only 3 heaters in their own room, so would be pointless) so don't see that anymore. Just the slider or the selector for a program.
