So Drayton wasn't really interested in helping - despite this being my fifth failure. I fully expect all my 2017 stats to fail at some point in the future. Drayton support asked questions like have I tried moving it closer to the hub or resetting it. This despite me telling them in the initial ticket it was dead, no LEDs with new batteries!

Amazon was helpful though. I bought my last stat from them in June last year so they replaced "that" foc. Got it the next day and Hermes picked up the dead one the day after. I keep one spare stat now in anticipation of these failures.
