My use case is the following.
I have an really high quality but ‘dumb’ air purifier.
I’ve figured out a way how I could make it look “smart”.
It would have the following sensors:
- controlling the on/off (using a zigbee based IR remote)
- controlling fan speed (using a zigbee based IR remote)
- getting particle count (PM) using a small smart counter sitting right on top of it
- get temp and humidity similarly to above
This will replicate 100% the sensors that I have a newer smart air purifier I have other than an indicator when the filters are done (ALTHOUGH I could actually keep track of that using knowledge of the speed it’s been running at provided no one controls it directly from its remote which I’ll hide :P)
At this point, you could ask, why not just buy a new air purifier? This one is from IQAir, is quite expensive and very effective and I’ve had it for a while and it’s still rock solid (these things last over 10yrs in hospitals running 24/7).
So it is still vastly cheaper (and more fun!) for me to ‘smarten’ this using some cheap relatively cheap sensors.
Is it possible to define a template device? Or the best I can do is define a bunch of “unrelate” template sensors and just name them appropriately. And maybe actually there will be little value in having a template device other than if I need to somehow bind all these template sensors together if I want to target them as a whole in an automation…
