I read recently in an early group that dashing out could be caused by a baby alarm. Can't comment on that but it did lead me to check what I was using. I measure usage of electricity using a type of Smart Meter which works wirelessly. It is an Efergy Elete. I used to download the info from the device and leave near the Vantage Pro 2, but not every day. Since reading the earlier correspondance I no longer take it any were near the vantage Console and all the intermitant problems have gone. Food for thought and hoping it will not come back!!!
