[QUOTE="TritonT, post: 163324, member: 26020"] 4. Yep that's what I mean - I think my logic is correct! For most linear sensors the offset +/- number would not be required, but I think some people may require it, for example pressure sensors that read high by a certain amount. As a simple example, a AA battery tester connected to a Netiom xAP: The Netiom reads voltage on a 0 to 5v scale and reports this as on a scale of 0 to 1023 so we multiply by 0.00489 to get it back to a 0-5 scale. We don't need an offset cause 0 really is 0 (no sensor calibration required here, its only a battery). But when we display the range we want 1.5v to be the max, cause its only ever going to see 1.5v batteries. Obviously this is minority interest as most people will use the plugin for X10 control, so if you don't have time or you think it complicates the tab in the configuration too much don't give it another thought. 5.

Over the next couple of weeks, I'm going to have a go at some 1-wire and iButton stuff using Michael McSharry's xapmcs1Wire node, I'll report back. [/QUOTE]
