Runs when you save preferences.
Thanks @thebearmay , I wasn't sure if it also ran on device handler update. So @stueyhughes you definitely will need to press save preferences after updating DTH.
This is fabulous and mega appreciated @cjcharles. Just one observation if you can help. The thermostat can only be adjusted in whole degrees. I've been using the HE+ dashboard which allows 0.5 degree adjustment. Can you alter this with your code or is it a HE function?
Ah yes, I added support for it, but basically rounded the number as the Heatmiser API only accepted integers. From a quick google their API does now seem to support 0.5 increments so will do some testing of that.
Yeah heatmiser have supported 0.5 increments for a good year now. 
Hi all,
Having the same issue with the 'Generic Z-Wave Plus Thermostat' driver.
What now ?
