As a former Home Assistant user, I am pleased with Hubitat. The easy-of-use, the documentation, and the support forum. I understand that Hubitat is really about automation, not that much about reporting, graphing, etc. This is a good decision. However, adding an energy app to collect the stats of solar panels, P1 meter, and energy-consuming information from smart plugs/strips makes sense to me. You can add them to a dashboard or export them to Graphana using InfluxDB.

@inktvis75 You might be better served with an HEM V5 and export that data to influx. I mean without an API specific to your system that hubitat can see, there really isn't any other way to do this. As to power metering devices already on hubitat you should be able to already run this into influx
btw: I was already able to connect to SolarEdge, and I love the available tiles.
The P1 meter (https://www.zuidwijk.com/product/slimmelezer-plus/) is a ESPHome device, maybe I can write a driver myself. Smart Powerstrips in my home are Tasmota devices, that have a small webserver on board. So the data is there, but I am searching for a more standarized way to collect the data, have a possibility to create a dashboard, or idd export them.
I don't know what a HEM V5 device is, I will look it up.

Aeotec HEM v5 clamps to a power line in your breaker box, It measures by inductions (very accurate). The driver can log everything and you can export the logs to influx (same as you would a power metering plug)
While I do use influx / Grafana myself, the possibilities of having an app to take in various devices from various sources and produce a common output being a dashboard tile or tiles is an attractive proposition, regardless of the alternatives.

It's maybe halfway to the functionality of HAs energy dashboard, but it's a start. I was hoping someone would pick development back up.

I agree, that would be nice 
I am not a developer, sometimes I play around with code, some scripting etc.
But if I look at some of the code, it is most of time perfectly readable. At the moment I have not a clear idea where to start, but I think the first thing I need to do is find/develop a driver for the P1 reader, so I have at least some data I can play with.
That would be correct, as long as there is not an existing driver already
Nope, there is not, so I am going to start with https://raw.githubusercontent.com/Fanman76/Hubitat/master/HomewizardP1/hwp1_driver.groovy and the ESPHome + Hubitat topic
Again, I am not a developer, so wish me luck
