UNSOLVED battery_voltage and STOP-command are missing

[GeorgeA]

My Hunter Douglas blinds (HmIP-HDM5) and remotes are currently all connected to my Homematic IP.
This has the advantage that also the native Homematic IP app can be used.

Via ioBroker and Node Red I can send and receive the the blind settings and status. But what I'm missing are:

• battery_voltage
• STOP-command

When connecting one of these blinds directly to RaspiMatic the battery_voltage can be retrieved and an action in progress can be stopped by sending a STOP-message to the corresponding channel/entry of the device in RaspiMatic. E.g.:

var stop = 1;
msg = { stop: stop }
return msg;

I couldn't find a solution or answer on the forum. Have I missed it or is this a feature request?
