Device (alternator) temperature not showing up in list for Relay Temperature Controls

Q&A and troubleshooting

I have a Wakespeed WS500 attached to my Cerbo GX. When the engine is running, and it’s on, I’m able to see it in the device list with all its power stats (I have a shunt measuring it) as well as parameters such as Alternator Temperature, Speed, and Engine speed (on my system, the alternator, or in this case, the Wakespeed, controls the tachometer at my helm).

I’ve been having some temperature issues that can be easily resolved by pointing a 12V blower at the alternator, which I’d like to have controlled by the CerboGX Relay. However, the Alternator Temperature doesn’t appear in the list of options (even while things are running)–only my Exterior temp (a RuuviTag sensor) is shown in the list.

Am I missing something?

Somewhat related: though the Alternator Speed shows up as a value in SignalK through the Victron plugin, Engine Speed does not…

Temperatures from secondary sources do not show up as temperature sources for the relay function, so WS500 or Mopeka level sensors etc.

I am not sure if this appears in Node Red Alternator node or the Custom Input node. I know that the Mopeka level sensor temperature can be accessed this way. I am not on my boat at the moment so I can not get my WS500 running and Node Red can not find it with it off. You could look on Node Red and if so program the blower this way.
