    Hi, I had some issues with my smart watering as I started irrigating this spring. It was watering way to frequently despite having mild temperatures. It was also not updating irrigation events properly. I.e., showing 0% water content in a sector immediately after irrigation. A chat with b.hive support resulted in them updating my system in the background and sending me back to observe if things fixed themselves. It seems that it is now updating the water content, however it seems to still be ‘drying up’ too fast, and watering too frequently. I am using the default smart watering parameters. So, that sent me into the rabbit hole of trying to figure out and adjust the advanced parameters. However, the help file is not very helpful for the Plant Factor (Kp). It indicates that Kp is a fraction, and provides examples of numbers from 0.3 to 0.9 depending on the plant type. Yet, the actual Kp number that appears in the Advanced Settings is not a fraction like that. It is in units of evapotranspiration. For example, my default value is 1.78 cm/day. So, what really goes in the Plant Factor field?

    I am kind of disappointed that no one has answered my question. So feel like re-writing my question, in case it was not clear. When I say that its ‘drying up’ too fast. I mean the smart watering soil moisture graph is going down in one day. One day I set it to 100% (because the soil is nice and moist), and by the next day it is reading near 0%, and running the water again. This despite 70F weather… granted, with some wind, but still, soil is visibly moist because it has been watering every 2-3 days for the past few weeks of me trying to fix this. The reference evapotranspiration (ET0) shown in the advanced parameters seems reasonable (yesterday it was about 0.25cm/day, I think). It matches what I get at CIMIS. This means that, all things being equal and average, it would take 4 days to get down to 1cm depth. So, why does it run out of available water overnight?? I thought that maybe the plant factor maybe too high; e.i., it is thinking that the plants are drinking that up really fast. Maybe I have a more sparse planting that the default value assumes. According to the help file, the plant factor should be a fraction of ET0. 1.0 would be the same as the ET0 (plus whatever other parameters). But the plant factor in the Advanced parameters says 1.78cm per day. That is not a faction. Is it saying that its thinking that it dries up 1.78 cm/day?

    @taniabrenes I apologize about the delayed response, it appears yours system has started to level out, are you still experiencing these issues? Please email me at [email protected] for better and faster communication. Just put attn Stephen in the subject line.
