So, living in the Tri-Cities where I do, one event I watch for in April is the irrigation water coming on. That is available at the hydrant (don’t think fire hydrant ok) and I checked it this AM and seeing that it was on left it on so at 10AM or so I’d see that sprinklers were messed up etc.  Well, when I left this am to get the morning coffee, there was water EVERYWHERE out front. Â
The timer must have forgot to come on at 10AM, and so came on early in what I call Zone 1 (out front) there were issues, I then called Ray the handyman and showed him a video, so the summary don’t expect the battery powered timer to be all that smart.
