For a tiny script, I would need to dynamically modify the grid set point. However, it seems that ESS is not accepting user-setting values on dbus, as long as it's running in ESS-Mode 2.
Switching to complete external control is something I would to avoid for this tiny script to make it as portable as possible.
Just to clearify, following value would be the "correct" one to alter?
/Settings/CGwacs/AcPowerSetPoint
