ChargeVoltage set zero when MultiPlus II connected

@dognose

this could mean that your “external control loop” is responsible to maintain that value

I tried. I wrote /Hub/ChargeVoltage, but after about 1 sec it gets overwritten with 0 by ‘unknown’…

and see 19th - somehow some value nowhere to be found appeared (and disappeared…)

I still think that this is simply a bug… The manual is clear…
