I have a Sinope Water Valve hooked to a C-7 (latest firmware, updated today) with the displayed flow (notes as rate).
I want to pass that specific info to my C-5 (firmware 2.2.3.119) through node-red.
I can pass variables like temperatures from various devices (ecowitt) from C7 to C5 (maker api)
But I'm unable to pass that rate variable (even I can see the rate FROM the C7)
What will be the NR instructions to pass that value from C7 to C5 ?
As you can see, the C5 variable is noted as a virtual temperature sensor (there is no valve rate on my C5).
Anyway, if you must use NR, you’ll need a custom virtual driver that supports rate as an attribute, and has a command like setRate to set the value of that attribute.
The Hub Mesh route would be simpler, but will require that both hubs be on the same platform version.
I use NR because I already use it for various purposes (integration of hubitat units, industrial PLC (modbus) and serial devices (volt meters).
Because my C5 is running ok, I don't want to update the firmware (I had problems when I did it)
but I wonder why a virtual driver?
Isn't it "just" a message that needs to be translated under NR, converting one value to another?
I have lots of parameters that are "other" values that become temperatures, by simplification (and I can change the attribute and replace the unit in Hubitat with another.
will submit some example later
thank you
Update.
In fact, when I use some comversion between devices through NR, I convert in Hubitat (prior to NR) a value to a temperature (whatever parameter) into temperature. The NR gateway transmits this parameter (temperature) between devices and I use it in the new Hubitat.
I'll probably convert the Sinope rate (C7) to a temperature (virtual sensor), send it through NR and use it as "temperature" in my C5 (with a label as L/min instead of C)
Found my solution !
C7: Sinope.rate => virtual temp sensor
C7: Rule : virtual temp sensor = Sinope.rate if changed
NR: exchange temperature sensor (C7) to temperature sensor (C5)
C5: display and use virtual temp sensor (and display L/min unit
