I had the same idea once. I would have to study the settings then.
But now I am curious. My heatpump does very seldom goes to max and I don’t now why. Right now it is only consuming 5.1 amps. It is norminated for 10 amps.
How are yours values?
I have a 11.5 kwh heater, never went above 2 since I started to use it beginning of this season.
I am fine with removing off as a state if I can continue to toggle on/off. (I am still on the test version, works fine.)

2 amps or 2 degrees?
Sorry for being unclear. Heater is up to 11.4 kW but the effect I see is up to about 2.2 kW max.
I am working that now, but this will make any flows that uses the old thermostat mode invalid.
I cannot convert those, so they will need to be updated manually.
By the way, I have found a bug in the current version. The frequency is not the frequency, it is the exhaust temperature.
In the next version this is fixed.
I am experimenting with this right now. I have found the setting for the inverter frequency when in silent mode. And the fan speed.
Also it may be possible to set the maximum frequency when in normal mode.
The values are there, but I have not yet tried changing them.
Hey,
That’s most likely 11.4 kW of thermal output. Most heat pumps have a COP (Coefficient of Performance) of around 5 giving 11.4 kW of thermal energy when only using 2.2 kW of electrical energy.
Every 1 kWh of electricity consumed, it delivers 5.2 kWh of heat energy.

A quick update. I have managed to manually set the frequency of the compressor directly from homey when in silent mode. I have changed it from 50 to 40 hertz and it worked.

Another update. I cannot change the fan speed in silent mode. I can change something that should be that, but it does not change anything. It seems to be stuck in 300 rpm.
Makes sense that you can’t set the fan speed to a lower number, as it must be able to give enough airflow for the compressor to do it’s job.
I wonder if the fan speed auto-adjusts if you set it to ‘auto’ and vhange the compressor to let’s say 40%. That’s a low number and it should bring the fan speed down.
Discovered a small error @Jesper_Rasmussen . Onve the heatpump reaches temperature and shuts down, the frequency stays at the last value instead of going to 0.

I wrote a couple of days ago, you may have missed it:

That is why. It is not at all the frequency it shows 
Yes, maybe.
If not in silent mode, but in normal mode, it can change the max and min fan speed. That works.
Next up I will experiment with changing min and max frequency of the compressor, when in normal heating mode.
Btw. I did not try to adjust the fan speed down but but up (in silent mode) But it did not react at all.
Just an update on my experiments.
I can now change the max frequency of the compressor, and it works.
Having the heatpump in normal heating mode, and the frequency is 75 hertz, and change it down to 50 works. It immediately turns down to 50 hertz. However it is very slow to ramp again. But that is a generel observation on my heatpump. It takes it 2 hours to go from start hertz (52) to 80 hertz.
I now have it implemented in the homey app, that you can go into device settings, and enable experimental features. After that you can change the max and min fan speed, and change the maximum frequency in heating mode.
Tomorrow I will try to implement flow actions, so that you can change the values from flows as well.
–
So now version 1.8.1 is ready for test.
With that you can enable experimental features, and when they are enabled, you can:
- Control the minimum fan speed in normal heating mode
- Control the maximum fan speed in normal heating mode
- Control the maximum frequency of the inverter / compressor in normal heating mode.
I have testet it allot on my own heatpump, and it works great, but there are no garanties.
While fan speed is working right away (you can hear it turning up or down when you change the slider in the homey app) the frequency is more slow. It will turn the frequency down immediately but ramping up seems to be a slow process. In my test I changed the maximum frequency to 50 hz, and then back up to 90 hz. It took 3 hours before it went up again.
I have a weird issue now. Every action i try to switch on the heatpump (flow or manually) is overridden after a few seconds by the app itself. So i can’t switch it on now
Hmm does it work from the official app?
Otherwise please send a diagnostics report so I can look at some log.
This is very similar to what I have reported earlier as strange behaviour. For me it happens rarely.
