After several weeks of real-world testing across a handful of Marstek installations, I’m happy to share the first community-ready release of the Marstek Local API integration for Home Assistant.
Try it out
Grab the integration, wire it up to your batteries, and let me know how it runs in your setup. Please report issues or requests on GitHub so we can track them properly.
Looking forward to hearing how you put the “Marstek System” in action!
Good evening, the Marstek local API integration is causing disconnections between the Marstek Venus E battery and the CT002. How can this problem be resolved? Thank you.
This is a known issue. I had this happen when i polled the batteries too often. But the default of 60s seem to work fine. My batteries no rarely loose their connection. If they do a reset of my CT003 usually solves it. Not perfect. Hope Marstek comes with a solution.
Hi
When I look at the BLE Monitor it seems that Local API was eabled by default on Port 28417. But when I run the command to Disable it or Enable it with another Port nothing is changing. Did a Update from stock V122 to V139 today and have the same behaviour. Do you know what I can try?
I have the Venus E V3
Greetings
Update: Contacted support yesterday and got a response today that they activated it. I have an option in the app now to activate it and set the port and it works.
Most of the sensors are Unknown or incorrect for me. Battery % is correct. It says charging while discharging. Remaining capacity is also incorrect. Really pleased with the development but something is going wrong for me. The FW of the Marstek V3 is V139
