I have just become the owner of my first pool, so please be gentle
The pool and all the equipment is quite old, the SWC is about 8 years old by the stamps on it.
Basically it all works but as I replace failed parts I would like to do so with automation in mind, when I say automation I am talking about open-source linux monitoring specifically with things like the ninja block, so the sensors and actuators shouldn't use proprietary interfaces or overly complex encoding of the data.
So the things that spring to mind:
I was thinking it would be cool to be able to measure the flow speed of the water, this would perhaps tell me when the skimmer was full, or the sand filter needed a backwash, maybe even if the pump was broken, is there a way to add this, maybe plumb in a flow sensor that talks to an arduino and then back to the HA using a 433MHz radio, anyone done this, is it worthwhile?
The circuit looks interesting: http://atlas-scientific.com/product_pag ... lo-30.html but the meters they have (rotoflow) don't look suitable.
Measuring the efficiency of the SWC and maybe being able to adjust it?
Temperature sensors would be good, what would be the optimal placement for those, is anyone aware of suitable 433Mhz probes?
Switching the pump on/off is probably the easy one as I can get a 433Mhz power point that can be controlled by the HA controller.
I don't have lights, heating or any valves, so I can't see anything to do there.
It would be cool to have the sand filter automated, right now its just a bid black tub with a huge manual selector dial
Thanks for your time.
