vollevel not working?

[madcat-nl]

When i send:
{"cmd":"vollevel","value":25}

i receive an error:
fsm.connection.setVolumePercent is not a function"

volumeup or volumedown is working fine

[Prinsie]

same here. That is the only function I want to use ':)

I'm also hoping to use this Node Red node to control a Marantz control compatible device.

I read this in the Marantz documentation:

The PARAMETER (with COMMAND and RESPONSE, EVENT) of minimum level of MASTER VOLUME defines “99”.
D) If the MASTER VOLUME & CHANNEL VOLUME set with 0.5dB step, the PARAMETER (with COMMAND and RESPONSE, EVENT) defines three ASCII
characters as bellows.
Ex. MASTER VOLUME = +1.0dB : MV81 +0.5dB : MV805 0dB : MV80 -0.5dB :MV795
-1.0dB :MV79 ||
-79.5dB : -80.0dB :
-80.5dB :
MV005 MV00
MV995
--- : MV99 * At the **.0dB step, only uses two ASCII characters as PARAMETER, same as usual.
