Thanks, Gareth 0 Gareth Roberts 03 September 2016 12:46 To follow up - I have 3 sensors. The 2 that I have done the Firmware Upgrade to New Version: 2.7 Build 1070 show the 'NaN', but the 1 I have not upgraded still shows the numeric value I entered for the standing charge and rate per day. Is this a bug with the upgrade maybe? Or something else? Thanks, Gareth Please sign in to leave a comment.
