Hi all, something is wrong with my setup in my ENERGY-dashboard …
I have 3 PV-installations.
I created a helper for each installation.
When i add these to my energy-dashboard, i get a really crazy graph which is not correct …
Any idea what i am doing wrong here?

The screenshot which mentions “live” is showing values with kWh unit and that sounds a bit confusion to me. Is this the produced energy of today? Or the instantaneous power that is currently being generated as that should be in kW, not kWh.
Just mentioning this because a lot of people confuse kW and kWh, and messing those up can mess up these dashboards.
Hi Kenneth, live is the actual production, not the produced energy of that day. I just changed my ‘helpers’ from kWh to kW and get another graph now.But seems not correct yet …On the graph it says kWh …
Ok, so the live data (the template sensor) is now kW, great. I’d expect those values to go up and down as sun conditions change.
The energy dashboard needs kWhs however. This means you’ll either need another template sensor that processes another value from the inverter (e.g. some energy sensor in Wh that you would also divide by 1000), or a sensor where the instantaneous power from the first sensor is integrated into power-over-time / energy (kWh), see Integral - Home Assistant
I’d strongly suggest you read Understanding Home Energy Management - Home Assistant as this might clear out a lot of the questions that typically arise when setting up the energy dashboard.
I’m a little confused by the scale of the graph. 0.15kWh doesn’t seem right. If your instantaneous system power is 2.56kW (not kWh) in 1 hour it should produce 2.56kW of energy (note: power vs. energy).
The graph itself is not unusual. It could be an intermittent cloudy day. Here is my power for the last two days. The black is my grid connection, dark green roof solar, light green heat pump minus hill solar. Yesterday and the day before were cloudy noted by the jaggy lines, today is perfect sun, noted by the smooth changes.
I suspect that your graph is the energy (kWh) for one hour, thus kWh.
(I am not using HA but will be in the future. The technology I am using has been abandonded. 
and I will have to shift over to an open source technology, probably Open Energy or redesign my own design to accommodate more circuits, the former being vastly superior.)
Because you still have historical data that was recorded with the wrong unit. Go to your stats tab under the dev tools and check for any repair messages.
