I have 7 older timers from last year and the year before. I don’t dare touch them now because they are still working based off what I had setup last year. Two new I bought are blinking flashing with this firmware update issue. Amazon will send two more so I am not worried about that.
Last year I had 1 of my 7 stop working. Simply would not open the valve even when the device worked. Warranty worked pretty well, they just give you a code and you order a new one from their site for free with free shipping. So they replace it without issue.
Hopefully they will push a fix. I chatted with support and they said Saturday they would push the fix. But who knows, I won’t try to setup the new ones or return old ones until we get a fix.
Good luck everyone!
