Beem Energy Solar Power Configuration

malendure · August 31, 2023, 10:20pm

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.

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… 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.

Authorization: Bearer {{ states.sensor.beem_token.state }}

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:

Hello Everyone,
I have a Beem Roof and would like show data of beem app on home assistant.
Beem Energy & Beem Energy looks not working … When I am going on, I only obtain beem logo.
Is it still working at your side ?

Best regards

Klau · September 3, 2024, 8:15pm

Hi Charly3944, I had the same with Google Chrome browser but not with Brave browser. Then, I deactivated the Chrome extension “uBlock Origin app” and it works.
Best,
K.

Hi @Klau
Thanks.
I checked and still unable to find bearer code via inspect from Chrome

So, I saved below code on packages/beem.yaml & token well appear in the secret.yaml
But still face to issue as sensor well created in home assistant & sensor doesn’t show any value.

Is it due to bearer code find is not correct ?
or because I have Solar Panel without beem box. (I am with a beem roof + battery)

template:
  - sensor:
      - name: post_data

I tried to use postman.co to obtain direct result
POST option on BEEM api website : https://api-x.beem.energy/beemapp/box/summary

Bearer Token set in the Authorization tab & below code on Body tab:

{
    "email": "[email protected]",
    "password": "change by password",
    "month": "9",
    "year": "2024",
    "sensor": [
        {
            "name": "beem",
            "json_attributes_path": "$[0]",
            "json_attributes": [
                "boxId",
                "totalMonth",
                "wattHour",
                "totalDay"
            ],
            "value_template": "OK"
        }
    ]
}

Result is empty : []
I tried to inspect website but didn’t find how to obtain data…
