I have a Solaredge 10kw Grid tied system. I have added a 6kw Hybrid Sungold Bluepower IP6048 connected to a 48v NiFe battery. I have a Tesla Gateway not a powerwall or inverter just the gateway as my disconnect to island my house if I were to lose grid power. I have been working with a Raspberry Pi 3 with Venos Os in an attempt to pull some of these disparate systems into one console. I can live with not controlling them but just seeing what they are all doing in 1 console screen. I have also added a Mopeka Propane tank sensor to my 100 Gallon propane tank. So far it is coming along.

I got the Solaredge to show up. Albeit not sure why it is a negative value. The sun is already set so only seeing 96 watts of production. I was able to get into "Setapp" and make the SunSpec changes mentioned in the linked forum. My inverter said Multiphase but is actually a single phase or US Split Phase and although I read that I was supposed to be able to change this I could not. I later found this repo and my solaredge info made it onto the screen. I was playing around with GUI Mods but need to turn some of that off. Picture of this at the bottom

I have an emporium vue monitoring 16 of my circuits. There is an unofficial API to pull the data. They have some really nice displays but would prefer it to just be brought in as an AC Load in the display below. I am confident I can get at the data just not sure how to bring it into Venus OS without breaking it. I will paste the links that Emporia support sent to me. Most are based on the Pyemvue github. just not sure how to bring it in and it play nice with all the other Venus OS stuff. I don't think this would be a heavy lift but some guidance would be greatly appreciated. I guess I can try and if it breaks I am pretty sure I can start over and get back to where I am.

I have a Victron Smart Shunt but need to get the VE direct cable to connect between it and the Rpi. Its about 40ft. I have my NiFe batteries in a shed away from the house as they can off gas hydrogen. I wish I could connect a wemos D1 mini to it and send that data wirelessly but will get it hard wired at some point. I have another Raspberry pi 3 but not sure if the data can be aggregated into one console. I will try the hard wired method.

I still need to figure how and if I can even get CAN bus talking. I did add the isolated Double CAN adapter to the rpi. The Tesla Gateway and the Sungold are supposed to have CAN interfaces but no idea if it will use a standard or proprietary flavor.

I am sure I have missed or forgotten something but this should be a good start for a conversation.
