Ok, it seems to be OK... ???

So.... it works?

Keep in mind that:

• The scrape interval is 300s, so you'll only have data available after 5 mins. (the ECU only updates this data every 5 mins: ¯_(ツ)_/¯ .
• These sensors will only be available after a restart of HA.

at this time, i've still not consumed energy, i'll tell you... thx

Everything is Ok !!! Thanks !

Hi ! Everythings seems to be OK but today i've lost one hour in my dashboard...do you know why ?

You're not giving me a lot to go on there buddy. That said, I don't think data is 'gone' but was just acquired at a later point in time. Probably Home Assistant was unable to reach the ECU for some reason. I would not worry about it too much tbh.

Indeed, they were grouped together later, after restarting the ECU-C.

I was forced to restart it because it stopped responding to ping and seemed unreachable. It happened again 3 days later... :|
Do you know why it crashes sometimes? and how can we ensure that this doesn’t happen?

Hello,

I have followed all the steps provided, however, I still see zero production despite another consumption tracking module indicating overproduction. I specifically need the status "sensor.solar_energy_produced". The version of the add-on "APSystems ECU-R" I am using is v1.4.1.

Could you please assist me with this?

Thank you in advance.

Edit : After uninstall / reinstall its work now

Thank you for this code @wildekek . It works perfectly :-)

Hey @wildekek, I would like to suggest one additional feature that will add the "Imported/Exported" sensor to Home Assistant replicating the values you get in the APSystems app. That would be the grey line in the screenshot below:

We can get these values from this URL: 'http:///index.php/meter/old_meter_power_graph'

To create this new sensor would only require adding the code below to the existing ecu.yaml

# Update the IP (192.168.0.6) to the address your ECU runs at
      - platform: rest
	name: "Import Export Power" # Grid Import is (+) / Export is (-)
	unique_id: import_export_power
	device_class: power
	state_class: measurement
	unit_of_measurement: W
	resource: http://192.168.0.6/index.php/meter/old_meter_power_graph
	scan_interval: 300
	value_template: >
		{% if value_json is defined %}
				{{ value_json.power2[-1].powerA }}
		{% else %}
				{{ "None" }}
		{% endif %}

Please, let me know what you think. And congratulations again for the great work.

Hello, as there is a clamp at the counter, which entity corresponds to consumption or instant injection? I need to recover this value. Thanks for the work

Bonjour,
Avant de commencer l'intégration je voudrais savoir si vous avez eu des coupures pour être obliger de redémarrer l'ECU_C ?
Merci

OK, peut-être un problème avec mon configuration.yaml...

Est-ce correct ? `#renvoi vers sensors sensor: !include sensors.yaml automation: !include automations.yaml script: !include scripts.yaml scene: !include scenes.yaml

#renvoi vers les paquets (ECU-C) homeassistant: packages: system: !include packages/ecu.yaml`

Je peux voir des capteurs dans les outils de développement mais je ne peux pas les sélectionner sur mon tableau de bord énergétique.

ca ne marche pas
pouvez vous refaire le yaml en entier
merci de votre retour

Hi, since yesterday, i can't get data anymore...Do you know if anything has changed ??
