I think I have the same issue (I created a new thread then found this one). Sprinkler falls off the network and does not reconnect. I don’t know if it says ‘reconnecting’, next time I will check. The time I did check I was able to see the IP address on the Sprinkler. Where do you see it say reconnecting?
To fix the issue, I don’t reboot the Sprinkler, I disable the re-enable the WIFI on my router (I don’t reboot the router, just turn of the WIFI then back on). It then reliably reconnects .
App: 1.8.2, Firmware: 2.1.8(2), Hardware version: 3.0 DC
I have a second router I will try soon.
