At the moment I am trying to optimally control the Marstek Venus E3 for the supply of energy at the right moments. We have a lot of solar panels and this beautiful weather power over. At the moment, energy prices are skyrocketing and that is why I want to use the system optimally.
The Venus works well via the app, but the possibilities are limited. With the B2500d card in HA you get a nice picture of the data that is used from the Venus.
The control with HA is still not 100%. This is because the collaboration with the Marstek app does not work. I used the HA App Modbus Proxy for this and that works well, but you have to turn off the Marstek App on your phone completely.
The problem I am facing now is:
The Venus will now deliver back in the evening itself. This is not set anywhere and it will switch on as we call it “zero on the counter”. How can this be adjusted? Thanks for the support.
