Very happy with product so far (day 1), tested all my scenarios and works as expected.
Something I am very happy about and is good to know for anyone buying is that all commands and settings are stored and executed on the tap timer, which means the timer never needs to rely on WIFI or mains power to turn off.
Even manual watering, it sends the command to turn on along with the duration to stay on for (eg. manual water for 15mins), in other words you can turn it on manually for 15mins with your phone, turn off your WIFI (unplug hub) and it will still turn off no worries (coz everything is stored/sent to the tap timer).
If anything changes (happiness level), I will be sure to post again.
p.s. watch the water proof rating IP54 (which is low), rang support and they said it's designed for taps up against houses (they claim sees less rain), I have mine under complete cover for this reason.
