Hi all,
I see that there has just been an update to the detection
of the Carel pCo controllers, which has added a lot of new
sensor definitions for many people I expect (a good thing
would have been an awful lot of work for someone which is
appreciated of course!).
Unfortunately, as the pCo is a programmable unit (and we
are an OEM/unit programmer for Carel) we use the units for a
large number of custom applications across a number of our
facilities and customers. Previously we weren’t getting any
sensor-specific
information via Observium for these units (just network,
CPU, ram etc.) which is OK as we use other BMS systems to
get the environmental data.
Since the last update, we are getting a load of sensors
but unfortunately (since our units are programmed by us)
they are now showing alarms across most of the output, for
example:
The values being polled are also non-sensical because
whatever the OIDs which are being used are either not
aligned to anything we use or just totally irrelevant
values.
Humidity example below (obviously it’s not 3,4 and 16 %):
Interestingly, we do also have some ‘official’ Carel
chiller controllers (running genuine Airedale control pCO
units, not our own) – and these are also showing crazy
values as chillers (no matter where you get them from) do
not have ‘Delivery Air Temperature’
or ‘Humidification Proportional Bands’ as they don’t’ deal
with air directly - for example:
So it appears the detection logic is not just limited to
incorrectly identifying our own custom controllers but also
those of other manufacturers like Airedale, who also use
Carel OEM pCO hardware like us.
With all this in mind, can I ask what is the best way to
prevent these devices from being detected as “ Carel pCOWeb
(Chiller Unit) “. So that they go back to being simple
pCOWeb units with basic stats like Ethernet and CPU?
Example device data is:
So like I said at the start, I fully appreciate there was
a lot of effort by someone to get all these sensors setup
and that’s great for people using the software they were
configured to detect. I just need to ‘not’ detect our units
as being the same really.
Input welcome :)
Cheers!
