OpenEVSE Demand Shaper Settings

@glyn.hudson @Trystan.lea

From Resources/Forum it’s clear that divert mode can be controlled by MQTT:

Topic: /divertmode/set

Value: 1 = Normal and 2 = ECO-mode

I can find no similar MQTT facility for changing the Light Green Bar in Demand Shaper which sets the charge limit for cheap rate night charging. It seems this can only be changed by opening Demand Shaper and then mouse dragging the bar to the desired limit.

Is it possible to use MQTT instead?

Can this enhancement be added?
