Additional info

combined with two measurment - during first one power measure script did exception (and in normal use it's very hard to empty battery)

@theundefined cool, thanks for the contribution.

Do you have some graphs from HA entities both the vacuum and power sensor?
Similar as shared here: #639

Interested in how the vacuum is behaving after fully charged. And if the profile correctly represents that.

Hello! I'ts more complicated here. There are two things missing in profile:

1. vacuum when goes to base every few dockings (not every time!) suck dust from robot to base. In that moment it increase own power for few seconds. It's directly after docking, and every 2-3 cleanings (depends on configuration):
   

next, after charging it look's like:

combination of battery level and power from shelly

hm. now when i look at it - it's more and more complicated:

• during cleanup phase - it take about 0.5-0.7W (robot it's not docked)
• when docking and sucking it takes ~700-800W (for about 10 seconds) - but only when suck. I don't see any changes in home assistant in that phase
• when docked and charging it takes ~20W
• After charging it slowly decrease taken power from 20W do ~3W for 40 minutes

Hmmm yes, it's complicated.

See my thoughts in the chart.
Sleep_power as referenced is used here: https://github.com/bramstroker/homeassistant-powercalc/blob/master/profile_library/harman%20kardon/HK%20Citation%20MultiBeam%20700/model.json#L27

It's not usable currently but might be a direction we can investigate.

For the sucking phase after dock I need to think about that, no obvious solution yet.
Might need to have a look at supporting composite strategy in model.json, that would provide much flexibility combining different strategies and conditions when a certain strategy applies.
Might also add some delay or duration stuff there, but that won't be an easy development.

Very interesting. Yesterday I took the measurements via the script for a Xiaomi X10+ vacuum robot and made the same observations.

I performed the suction of the base station manually at 80%. It is approx. 950 watts for 3 seconds during suction. I think you have to add this value at the end of the charge. (e.g. at 99%). If you add it at the beginning, e.g. at 5% charge, then it would never be added if the battery is not so far discharged.

In my model.json the value is calculated as 9.51 watt at 100%. The trickle charge calculation was performed for 1800 seconds.
In this phase, the consumption dropped from 20.9 to 5.3 watts and averaged 9.51 watts. The 5.3 watts were reached after approx. 11 minutes. The 5.3 watts also correspond to the standby consumption of the station when the robot is in the station or when it is vacuuming.
I would therefore say that you should not add the average value at 100%, but at 99%. Otherwise, the calculation for standby is too high when the robot is in the station and the battery is 100% charged.

What do you think?
