I am doing some research on how to control my Webasto Live-Wallbox through Modbus as I want to charge my EV with regard to PV-production and overall consumption of my home.
With the register addresses for TQ-DM100 I am able to receive all necessary information and can control the maximum ampere for the current session at 5004 “charge current in A”. What I do not see is an address to switch charging on and off when the EV is connected.
Sadly Webasto Support is not able to assist me on that case.
Another google search led me to the nymea plugin for Webasto Wallbox by @bernhard.trinnes - after some closer looks at the source code on github I wonder if you are able to start and stop charging and how you do it.
I understand that you work with the register addresses 5000 and 5001 as writable addresses. The documentation for the TQ-DM100 implementation by Webasto states that both addresses “charge power in W”.
Maybe you see a chance to assist me on that case even with my challence not being related to your project.
Thank you very much.
