OpenDTU Zero-Injection / Setpoint: Automatically limit inverters based on grid excess with Home Assistant and OpenDTU

README.md

Automatically limit inverters based on grid excess with Home Assistant and OpenDTU

Here is my Home Assistant OpenDTU dsashboard:

I sometimes need to be able to limit by production excess around a number to avoid retruning too much energy to the grid.

So I did a Home Assistant automation that is looking at the grid_power sensor to automatically adjutst the inverters' limit in order to keep the returned power at a specifed amount (setpoint).

The code supports also 3ERL API to limit the production when asked by 3ERL.

Zoom on the toolbar:

• Inverters: the number of inverters you have

• Nominal: the nominal power of the inverters (400W, 500W, 1000W, etc)

• Limit: this is an input where I can type (in manual mode) a limit to apply to all inverters. When in auto mode, this value is automatically computed by the algorithm depending on the excess.

• 3ERL Trend: 3ERL trend of the day as reported at https://3erl.fr/PREP_Profile.php

• 3ERL Zero-Inject: status activated (on) when 3ERL asks to limit the production (see their API at https://3erl.fr/api.json)

• Auto Limiter: status of the automation adjusting auomatically the inverters

• Setpoint: this is my desired level of excess to stick around. There are 2 setpoint: when the limiter is on, and when it is off. If set to 0, there will be a little excess and consumption. Setting it to -500W for example let me return little energy to the grid and also keep a buffer to start a VE charge for example. When limiter is off, I allow -2000W of excess, and when on, I allow -300W. But if my EV is plugged, I allow -600W to allow it to start a charge.

Installation

Putting that in place is super easy.

Make sure you have configured Home Assistant to support packages.

homeassistant:
  packages: !include_dir_named packages

Put the file opendtu.yaml in the packages folder:

Edit opendtu.yaml according to your needs and especially your sensor names, especially for:

• sensor.grid_power => your grid power
• sensor.inverter_1_power, sensor.inverter_2_power, sensor.inverter_3_power, etc: your inverters power. Note that I am only using that to compute a more accurate available number of active inverters. You could replace that by the number of inverters you have, the correction will take more minutes to apply.

Create a new dashboard view, edit its yaml and paste the content of view.yaml. It is possible that you'll need to install some missing UI components.

ok merci
j'avais déjà crée la ligne packages dans configuration.yaml
opendtu.yaml se charge je pense car j'ai les capteurs qui se sont crée dans l'aperçu général (non fonctionnel pour la plupart car je n'ai pas modifie leurs id dans votre script)
par contre view.yaml et opendtu_3erl.yaml ne se charge pas ou je ne sait pas par ou y accéder
j'ai la vérifié les .yaml dans outils de développement HA ne trouve pas d'erreur ...

je vois dans votre copie d'ecran que vous n'avez pas view.yaml dans le dossier package. Il doit se placer ailleurs ?

view.yaml c'est le yaml de la vue dashboard: quand on crée une section du dashboard, on peut aller voir son code yaml dans les options. C est ce yaml là.

ok j'ai crée un Dashboard supplémentaire view
mais quand je copie colle votre code dans l'editeur de configuration j'ai cette erreur a l'enregistrement ....
"Votre configuration n'est pas valide : r: At path: views -- Expected an array value, but received: undefined"....

I have updated the gist.
