1. Currently the minimum watering duration for manual program is 1 minute. If you want to water less than 1 min, you will have to go to the Home page, select your zones to water manually by tapping the blue button to do an instant manual run. I have talked to our R&D and we will support 30s' watering duration in future release of the app.
2. For the Smart Zone level basic. In this level, no smart schedule will be generated. It only depends on weather restriction(large amount of rain) or watering regulations. For more information about Netro smart watering, here is an article about Netro three watering modes which might be helpful. https://netrohome.com/forum/posts/111
3. If you select Add watering set for 50% to 1m in sensor's watering adjustment, it means Netro will start 1 minute watering when the moisture drops to 50%. However, there's not an exact date or time when the moisture drops to 50%. For example, if today the moisture drops to 50%, Netro will start watering for 1 min. However, if after a few hours today the moisture drops to 50% again, then Netro will water again because 1 min watering will not increase the moisture a lot.
We understand you need a shorter watering duration to avoid dripping onto your neighbour's balcony and I have forwarded your issue to our R&D. If you have any questions, you can reply to us or send us email to firstname.lastname@example.org.
I'll be looking forward to this 30 sec waterings.
Furthermore, you helped me to understand the algorithms better.
Thanks a lot,
You are very welcome and please let us know if you have any further questions,
One more thing that occured to me, while working my optimal settings out.
In the sensors menu for watering adjustment I can select "Moisture to Add Watering", but I can only select up to 50%. (iOS)
I observed my soil a little bit and decided that it might be already nice to water for one minute, once it reached 70%.
I assume the reason is, that the SW devs didn't want to implement a check to add reflective constraints to both the "Skip" and "Add" moisture. However, I think it would be nice to set the Skip to 85% and Add to e.g. 70%.
Right now, the threshold between add and skip is hardcoded to 50%.
Would be nice, if you could add this feature in a future version. :-)
Thanks for your suggestion and I will forward it to our R&D.
