Hi all,

I am looking to data log or at least view multiple temperature sensors throughout the property. I have a solar thermal system from Navitron which is controlled via an Ethernet enabled solar controller. However this controller only allows network access from within the LAN and must be run on a PC with the manufacturers software. I want to be able to display and log temperatures throughout my system including the hot water flow and return on the DHW tank and UFH system along with external temperature and the solar temperatures. I have a networked Heatmiser system which allows multiple sensor input but you have to use their digital sensors which is not ideal as I would like to utilise the current sensors in the system.

Has anyone any recommendations for a fully networked system for monitoring and logging multiple temperature inputs from both hot water and air temperature?

Excellent thank you.

Is the solar controller a TDC4? I believe the protocol in this device has been worked out so it's not hard to monitor it with other software than that provided by the manufacturer (which means you don't need a power-hungry PC to do the monititoring). IIRC our own djh wrote a little perl program to parse data from it. I don't know about the heatmiser stuff. In my experience 1-wire is by far the best way of having a lot of temp sensors round a building. (I've got 14 in this house). There are lots of ways of doing the actual monitoring of varying degrees of DIY.
