Silly question, but why don't people install temperature sensors on the water line going to the pump? (or do they?) That water is coming from the skimmers and main drain and is probably a good representative sample of the temperature.
I ask b/c i've been trying to rig up a system with a floating sensor, but a) it reads too close to the surface, b) it leaks and needs draining, drying, and re-sealing every couple of months, c) it needs batteries.
An electronic temperature probe in a pump line would only have good data while the pump was running, but other than that, can anyone think of downsides? (the pump itself heats the water a little, so you'd probably want the sensor before it.)
As for the mechanical details of what i'm imagining, i'd add a threaded tap to the side of the pipe and construct a modified plug with the sensor to screw into it, making replacement/modification easy.
