    Thanks for the info and link to the PDF, I'd found other docs but nothing as detailed as that one. I hadn't realised there was an internal T sensor as well as the external one, so now I understand.

      I intend to use something like this when I upgrade our hot water to have secondary return - i.e. continuous circulation. The idea here is that it doesn't need to be on all the time - once there's hot water in the pipe, the pump can turn off until the water in the pipe cools down again at which time the pump can come back on to get the pipe hot again.

        If you can route a phone or cat5 cable to the points of interest, would second smar's mysensors suggestion.
        I don't have pipes to monitor but room temperatures, currently 12 locations with DS18B20s on phone plugs, all connected via a single cat5e cable routed through the loft space, connected to a single pro mini with rfm69 banging only changes back to Domoticz every 5 minutes. Been running reliably since last December, but is USB powered with a battery standby. No idea of power usage on battery alone, but no reason you couldn't set up multiple nodes.
