With the scheduler, you can set up as many timed charge intervals as you want. Either keep switching the start and end times, or set the timed charge for 00:00 to 23:59 and use the scheduler to toggle timed charge on or off when required.

When you go away, I would turn off the heat pump (or turn it ...

This app doesn't work on an Ipad, and the message "no data received" is not from this app.

Maybe another app, such as Richard Russell's one?

Version 4.7.11 will be coming out in the next few days. There is nothing new, just fixing all the bugs I know about. The six issues fixed are:
1. Possible crash on systems with more than one inverter if a battery is broken.
2. Systems with multiple Inverters, second inverter battery data not toggled ...

With the premium version you can send commands to whichever ...

If you can find a way to change register 83 from 2610 to 2740, I think that should fix it.

Be careful, if you were to accidentally set it to 274 (which would be 27.4V) it may brick the inverter.

Version 4.7.9 wasn't quite perfect, so version 4.7.10 will be out soon, which just fixes one (hopefully last) bug. There are no new features in this update.
