June 7, 20233 yr Put my latest video up, please let me know what you guys think. Sound, editing etc is hopefully getting better with some practice. @kellerza I have a video of installing your integration on my todo list 🙂 Interested to do a comparison between Solar Assistant & Home Assistant at some stage but think I am a bit biased so looking for a Solar Assistant guru to assist if anyone is interested. Edited June 7, 20233 yr by Sc00bs
June 7, 20233 yr Would it be a comparison of the Kellerza integration and Solar Assistant in HA and what data / functionality they provide?

The data is fresher with @kellerza 's integration due to it connecting directly to the inverter rather than via the dongle - slower (Solarman) or via cloud - slowest (Sunsynk) I haven't done a speed comparison between the ESP32 & KellerZA integration and almost think it might become a pointless exercise as I don't think that most people require a refresh rate of faster than every 15 seconds and you have to remember that the higher the refresh rate, the faster your database will increase in size. I am no expert on Solar Assistant but suspect that one of the main advantages may be the way it connects to the batteries and interfaces between incompatible battery BMS's and inverters. Have no idea regarding it's flexibility in interfacing with IOT devices etc.

June 20, 20232 yr Hi I just want to find out if there was a post or where can I start looking of getting a Microcare inverter with their web logger or Volta batteries to communicate with Home Assistant or getting a ESP32 to communicate with these units. I will appreciate your feedback
June 20, 20232 yr Author Hi @Preston Unfortunately I have no experience with the Microcare inverters and I am not sure what interfaces it has. I would start of there, if there is a Modbus interface you have a pretty good chance of being able to pull data from it. Either a ESP32/RS485 or USB-RS485 would be a good start and would speak to Microcare to see if they have a Modbus protocol document available. I suspect that you would be breaking some new ground though as I don't recall anyone else as having gone down that path as yet (could be wrong) although a lot of the manufacturers seem to have a pretty common way of communicating with their inverters.

June 20, 20232 yr Mail them and ask them for the document that describes their RS485 protocol. Post it on the forum. Surely there are more people looking to build this type of integration
May 17May 17 So is it better to use Solar Assistant with RPi or use the Kellerza Home Assistant intergration?
