Titel: Aeotec Multisensor 7 - reset
Beitrag von: Paul Guijt am 07 Oktober 2025, 12:10:35
To reset my sensor, I currently unplug the USB for a few seconds.

I see in the Engineering Specifications on page 2 that it knows a Command Class 'Device Reset Locally'. In Attr classes, DEVICE_RESET_LOCALLY is included.

Would it be possible to send the sensor a reset command?

Regards,
Paul

As far as I see, this cannot be done.

I found no hint of this class in the "Application-Command-Class-Specification".
zwave.js seems to lack a command, it just parses the message (which FHEM also does).
According to the zave.me documentation (https://z-wave.me/manual/z-way/Command_Class_Reference.html#SECTION0016610000000000000000) :
ZitatReports to the controller that device was resetted locally (using local button operation).
[...]This means the device is certainly not in our network anymore

IMHO this would be too much of a reset for your purpose.

FHEM has a meterReset command...

Because humidity, temperature and others stop updating. A reset gets him running again.
I don't know what meterReset does. The issue is in the Multisensor, not in Fhem.

I'm in parallel working with Aeotec support. If anything relevant comes up, I will share it.

Its a ZWave command.

https://fhem.de/commandref_modular.html#ZWave-set-meterReset
ZitatReset all accumulated meter values.
Note: see meterSupported command and its output to detect if resetting the value is supported by the device.
The command will reset ALL accumulated values, it is not possible to choose a single value.
