Additional info

Could you share the device info from left top of device page?

[bramstroker]

What's the difference between these two states?

[rmalbrecht]

1. Switched off (standby)
2. switched on but not printing
3. switched on and printing

[rmalbrecht]

Sure:

1. Switched off (standby)
2. switched on but not printing
3. switched on and printing

Looking at the screenshot, currently the epson is unavailable.
Did you actually disconnected it or is this some sort of sleep mode where wifi is turned off making the printer unavailable to HA.

[rmalbrecht]

yes,

the printer stays in idle when not printing, after 60 minutes it goes to standby, after 4 hours it switches off. When switched of, the network interfaces, .mDNS, airport, .. is disabled and you need to manually switch on the device with a button on the printer.

[bramstroker]

What does it do with the consumption after this 60 seconds?
And after the 4 hours.
Can you measure that?

[rmalbrecht]

1. switched on & printing 14 watt
2. switched on & not printing: idle 7 watt
3. after 60 minutes of idle -> standby: 0,5 watt
4. after 4 hours of standby -> switch off -> unavailable, nothing that I can measure

What Epson says:
12 W (Kopieren ohne PC, ISO/IEC-Muster 24712), 1 W (Energiesparmodus), 5,4 W (Betriebsbereit), 0,2 W (ausgeschaltet), TEC 0,3 kWh/week

Epsons values are (unsurprisingly) a bit lower
0,2 Watt for off. That is nothing my devices can reliable measure.

[bramstroker]

• switched on & not printing: idle 7 watt

This is idle state in HA?

• after 60 minutes of idle -> standby: 0,5 watt

This is stopped state in HA right?
So it actually goes from idle -> stopped after 60 minutes, is that correct?

• after 4 hours of standby -> switch off -> unavailable, nothing that I can measure

We can use 0.2W for that.
Maybe we can utilize sleep power option for that.
But I must test that if it's working correctly when the printer entity gets unavailable.

Could you provide some state history, maybe the state history graph for one day, where also a printing job was done.
Maybe you can put the power sensor chart under it, when you still have the smart plug connected.
That will definitely help to see what state changes happens, and I will add a unit tests to simulate that behaviour, and to verify the profile we build will behave correctly.

[rmalbrecht]

Yes, this is also my understanding.
The IPP integration is mainly intended to monitor the ink levels; they don't change that fast. It seems to poll the printer state once an hour. Catching certain printer states needs some luck and tweaking:

Also, the IPP integration state entity is disabled by default. Unless the user manually enables it, it's not there.

In the usual household the printer will stay switched off 99% of the time and switched on when some printing is needed. Then it goes to idle after some (from the vendor) pre-configured and then finally switch off. The manual says, that this behavior also differs between countries.

You can see the smart plug for a short moment to display 15/16 watt while the printer is moving paper and the print heads:

HA is too slow to catch the 5 seconds the printer is doing something:

Or HA is averaging it out somehow.

[bramstroker]

@rmalbrecht Could you please add both the printer state and the power sensor in one graph?

You can do so by clicking history in the left menu in HA.
And than select both targets.

@rmalbrecht
Could you please follow up on my question from two weeks ago? The PR is currently blocked on that information, and once clarified we can proceed with merging.
