What are reporting consumed sensors?

[rzulian]

What are consumed sensors reporting? It's not really clear.
I though it was the daily consumed, but it doesn't look so. Moreover they are not changing at midnight, is this due to the time saving period?

[gekkekoe]

Previous daily consumed kWh (heating/cool/DHW).

it is reported around midnight. you probably have the time (summer time switch) set incorrectly.

btw, questions can be asked in the discussions section. will move this there eventually.

[rzulian]

Do you mean that is incorrect in the ecodan or in the component?
Do I need an utility meter to get it correctly, assuming the time is correct?

[gekkekoe]

setting in ecodan that has to be manually switched each season...

for meters please read #22

[rzulian]

I've tried to follow the instructions regarding the utility meters, but I think there is something wrong.
You are suggesting to use delta values = true, but the instructions are
Delta values Enable this if the source values are delta values since the last reading instead of absolute values. When this option is enabled, each new value received will be added as-is to the utility meter instead of adding the difference between the new value and previous value.
So the consumed sensors are already "daily utility meters", but the problem is that they are referring to the previous day. Is there a way to solve this? How are you getting these values in the energy dashboard?

[gekkekoe]

I have a homewizard energy meter, so I'm not using the reported numbers other than just an indication (they are far from accurate compared to the homewizard as explained in the other thread).

I haven't used the utility meters myself, but you should be able to read it daily. You might want to consult the home assistant forum, there's a melcloud integration thread, they are using the same reported values, and probably someone already did the work...

[rzulian]

How do you distinguish between DWH and cooling/heating using an external energy meter? Do you have a template enrgy meter based on the ecodan status?

Another question: is it available the total consumed energy from the beginning (always increasing) ? That would be perfect for the energy dashboard.

[gekkekoe]

I actually do not really care about the breakdown of the consumption. But you could make something based on the operation status via template sensors as you suggested. For me heating and cooling is the majority of the consumption, dhw is only small portion. I can look at the ecodan numbers to get an indication of the breakdown if I wanted.

For data that is available over cn105, please have a look at https://www.logicool-ac.com/wp-content/uploads/2018/08/MELCOBEMS-MINI-A1M-ATW-Modbus-Register-Tables.pdf and see whats available for FTC4, 5, 6. But given that it's not accurate, it's not really worthwhile to reverse engineer these. If you wire a pulse energy meter to the ecodan, then the number becomes accurate, but probably not a lot of ppl are doing this.

put this file in same folder as configuration.yaml
https://github.com/gekkekoe/esphome-ecodan-hp/blob/main/automations/energy.yaml
add entry in the config file:
utility_meter: !include energy.yaml
reboot, the values will accumulate on change, and will cycle monthly. You won't see anything until the first change.

[gekkekoe]

that seems a bit excessive, for me around 10-20%. Are you measuring the correct circuits? Also, the booster heater is not included on the main heatpump circuit.

But booster energy is also not included in consumption/delivery estimate

[gekkekoe]

no but he might be measuring it with Vue and compare it with the ecodan numbers.

[rzulian]

Yes, I'm measuring it using the Emporia Vue. I've installed the three CTs after the breaker for the Ecodan unit, so I should get all the energy.
Maybe I need a third system to check who is right?

[gekkekoe]

looks wrong probably, do you also have a total consumption meter? you can compare if the Vue is reporting more than the total consumption when using the heatpump.

[F1p]

@gekkekoe - I also had a 50W standby for the outdoor unit, but it's not accounted for in the estimated consumed figures - i think it only starts measuring when in an operation mode.

[gekkekoe]

you can check this in month that you do not use cooling/heating and the active mode is cooling/heating. If it reports 0 when you did not use it, then it does not account for it.
