Cannot change max grid charge current command MUCHGC #79

Open Fabio72 opened 2 years ago

Fabio72 commented 2 years ago

Hi, I'm using a Pi0 with an AXPERT VMIII

Everything is working fine, except changing max grid charge current. If I send commands like MUCHGC030 nothing happens. Rarely I can get an ACK, but most of the times nothing. Read value sometimes jumps to strange values like 33 or 63 after a try, but eventually go back to the previous value. I can change values with WatchPower app and bluetooth.

Using mpp-solar command I can change the parameter without problems

$ mpp-solar -p /dev/hidraw0 -c MUCHGC002 Command: MUCHGC002 - Set Utility Max Charging Current

Parameter Value Unit muchgc ACK

SuperMaximus1984 commented 1 year ago

I'm having the same problem. MQTT doesn't set any MUCHGC parameter, only polls the data from inverter. Where did you find "mpp-solar" command? Cannot find it in the image/docker container.

SuperMaximus1984 commented 1 year ago

I decided to opt for shell_command via mpp-solar. Using this method I can control the desired parameter

with the fork of catalinbordan/docker-voltronic-homeassistant seem to work fine i used the mqtt :)
