April 14, 20224 yr As per the topic: Will I have to remove the Solar Assistant PI before I can start with Nodered? Some of the things I envision to do: Scripting - ability to distinguish between weekdays and weekends for geyser usage. The ability to see both my PV Power devices. a different dashboard... I was also wondering if I could not just make up a RJ45 "duplicator" (1-to-2 device), not a splitter, to read the information from the Inverter by 2 devices? regards Aubrey
April 14, 20224 yr Hi, to my knowledge yes if you are wanting to run nodered on the same pi that solar assitant is currently running on. Solar assistant is designed purely as an inverter monitor with some control. You can use a second pi to run your automation and control and read the solar assitant values via mqtt and not have to use a splitter? In any case adding another device to read your inverter depends on what protocol your inverter is communicating with. I don't have enough experience to comment on the specifics but sharing your hardware details will help those better qualified to comment.

I already have a working Home Assistant reading the MQTT values, so I presume that will be it? Will I be able to use other people's dashboards?

You can use Nodered or Home Assistant, these are the two most popular I am aware of and if you are already using Home Assistant that makes sense. I don't know of any limitations using other people's dashboards but I haven't done any work in Home Assistant, I use Nodered.

Will start looking at the Nodered environemt soon... ps - will I be able to run nodered in a VM or do I need to run is on a PI?

The ability to see both my PV Power devices. a different dashboard... I noticed in the latest solar assistant beta they have started adding the ability to change inverter settings: https://solar-assistant.io/help/home-assistant/adjust-settings I've started playing with the home assistant automations and it does cater for everything I wanted to do. To some extent it reduces the need for node red. With home assistant I can also build custom dashboards that combine solar assistant data with data from other devices. Seems like solar assistant features are available first to voltronic/axpert inverters then afterwards for deye/sunsynk.
