Beem Energy Solar Power Configuration

Hi @mathuieu,

What additional information can you gather?

On my side, I use a Shelly 1 PM micromodule to verify the production. This is the only thing that matter.

Hi @Lennart-Live,

Can you post your configuration.yaml? We can’t help your otherwise.

Hi @malendure,
I connected my Homewizard energy socket to the solar panels powercord and from there i could see that the energy socket also measered solar panels production, so i created a new integration and added it to my energy dashboard. Also works great!

Hello,
Wellll, this also does not help me, because the energy socket shows negative power because it’s returning power from the Beem panels. HA does not understand this… :frowning: What to do next? I’ve tried the code again, but it gives me all these errors. It looks like there is a gap between versions of HA?
This is my version of HA:
Home Assistant 2023.9.1
Supervisor 2023.08.3
Operating System 10.5
Frontend-versie: 20230908.0 - latest

Thank you for all the work it’s been quite helpfull. I’ve had to change a line because it wasn’t working with the secret.

Dear Gurus, Thanks a lot for sharing your brilliant ideas - I learn a lot with this post - that I finally succeed to implement. Partially, in fact, since I have 2 Beem kits, and the text retrieved from the API holds 2 times the different variables:
`
[{
“boxId”:13435,
“name”:null,
“lastAlive”:“2024-03-27T09:18:24.489Z”,
“lastProduction”:“2024-03-27T09:17:00.000Z”,
“serialNumber”:“409151850C05”,
“totalMonth”:16405,
“wattHour”:0,
“totalDay”:0,
“weather”:null
}
,
{
“boxId”:12945,
“name”:“PignonEst”,
“lastAlive”:“2024-03-27T09:19:49.626Z”,
“lastProduction”:“2024-03-27T09:19:00.000Z”,
“serialNumber”:“58BF2539F03D”,
“totalMonth”:15104,
“wattHour”:0,
“totalDay”:0,
“weather”:null
}]

I guess an array is the solution but I have not enough experience in HA.
Should the format for the sensor be the following:
`sensor:
      - name: "beem"
        json_attributes_path: "$[0,1]"
`    
What will be the syntax for the state_attr, for example for wattHour:
`state: "{{ state_attr('sensor.beem','wattHour') | float/1000 }}"`
Best regards

Dear All,
Inspired from [RESTful - Home Assistant], I finally managed to read values from the 2 Beem Energy kits with the following configuration file using ‘beem1’ and ‘beem2’ sensors, instead of ‘beem’, as @malendure proposes:

# 'Beem Energy' Start

Thanks a lot again for sharing your knowledge.
