Sc00bs Posted June 7, 2023 Share Posted June 7, 2023 (edited) 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, 2023 by Sc00bs mzezman, slipx and cbrunsdon 3 Quote Link to comment Share on other sites More sharing options...
mzezman Posted June 7, 2023 Share Posted June 7, 2023 Would it be a comparison of the Kellerza integration and Solar Assistant in HA and what data / functionality they provide? Quote Link to comment Share on other sites More sharing options...

Preston Posted June 20, 2023 Share Posted June 20, 2023 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 Quote Link to comment Share on other sites More sharing options...
Sc00bs Posted June 20, 2023 Author Share Posted June 20, 2023 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.

iiznh Posted June 20, 2023 Share Posted June 20, 2023 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 Quote Link to comment Share on other sites More sharing options...
Preston Posted June 28, 2023 Share Posted June 28, 2023 Great thanks I will see what they say and if I receive anything I will post it. Quote Link to comment Share on other sites More sharing options...
