On this page I will share my setup of Tibber intergations, Homevolt information and automation plus Sungrow automation and information. Most of it is from different sources on the Home Assistant community. It can absolutely be made much more good looking so this is just an example how you can solve getting the information in the first place.
This is an example of some of the data we will show here. In coming threads I will add the components needed for this.
First of all we need some data from Tibber. If you have not done that yet, go to Tibber Developer and create an account to get your access token. Once ryou have it copy the token and create this entry in the secrets.yaml file:
tibber_token: Your access token in clear text
On the Tibber developer site you can run all types of queries to find out your house data. As an example:
{viewer {homes {consumption(resolution: HOURLY, last: 1) {nodes {from to cost unitPrice unitPriceVAT consumption consumptionUnit}}}}}
The result of this Query can look like this:
{
"data": {
"viewer": {
"homes": [
{
"consumption": {
"nodes": [
{
"from": "2025-06-24T08:00:00.000+02:00",
"to": "2025-06-24T09:00:00.000+02:00",
"cost": null,
"unitPrice": 0.2597125,
"unitPriceVAT": 0.0519425,
"consumption": null,
"consumptionUnit": "kWh"
}
]
}
}
]
}
}
For some of the integrations you will need HACS ( Home Assistant Community Store)
Initial configuration - HACS This is very helpful for everything you do with your HA so a very good add on.

Until we get the promissed API we can use REST to get some more info from our batteries.
The code below is a standard query to get info about the batter like SOC etc. Place this in the configuration.yaml file. You need to change the IP under - Resource: section. For me that is ip 192.168.1.91. You can get this info from our own AP or you can go to the web server for the battery and then to the command section and type in network as command and run that. In my case the output will partially be like this:
sta.if: UP
sta.idx: 3
sta.ifname: st2
sta.state: CONNECTED
sta.enabled: true
sta.configured: true
sta.error_reason: 0

Line 8 from the bottom: (states(‘sensor.tibber_pulse_hornkamsgatan_29_accumulated_consumption’) | float * 0.79875) is the amount of Kwh I have bought from Tibber times the cost per kWh i pay to Göteborg energi. That is the fluctuating price only, no effect tariffs. In other places I do specify that in more details. You can remove those lines entirely if you do not like to have the calculations.
I will not update this any longer. It is a Tibber vs my self trust issue so I have given up.
