Hi Simon, 

For the smart watering ,we checked for your zone "Raised Bed" and you selected dripper/emitter for your zones, this is why the zones have longer watering duration than other zones as dripping/emitter system is really slow in moving watering to the ground. 

EPA standard encourage longer water time and less water frequency, which will help growth of the roots. It will also break long water time to several small slots to prevent water runoff. If you think the smart schedules water too much , you can change to different smart zone mode (ECO). 

When Sprite finishes running a watering schedule, it will send a confirmation to the cloud server. In this way, the could server knows whether the schedules are correctly executed or not. The exclamation mark means the cloud server did not receive the confirmation from the device. There are two possible causes: 

1. the device is not powered up when it was supposed to be powered up to run that schedule. Therefore, the corresponding zone is not watered (what is why we use the exclamation to alert users) 

2. the schedule run fine but it was during a temporary network outage or exception so that the confirmation cannot be delivered to the server. Wireless connection can be unstable for a short peroid time so it is not uncommon to have a glitch in the communication. 

If the schedules afterwards are all correctly run, it could just be a temporary network issues. But if that happens a lot please check the WiFi signal strength.

If you use a WiFi extender, please make sure it is connected to the main router stably. 

Netro will send notification when the system is offline more than 24 hours. But you need to enable Netro App notification in your smart phone settings. 

Thanks, 

Wency
