😧 Emil or Émile in french, sorry about my long message.....
It's very strange, because mostly small and medium cities in the province of Quebec in Canada , have water restriction of 2 days only allowed to irrigate landscaping since many years, so I figure out It's base on a logic !. Also what mean Kcp ETo and ETc (I'm french speaking) to have a better understanding of your graph.
One more thing,
Base on my stats, I cut by 50% of water usage and had 35 skips schedule, so I was happy to told that to my wife and neighbour to justify my investment in Rachio last spring, but my wive told me two days ago, she observed infront the house there are zones that the grass seams dead and just beside those zones, the grass look good. So this morning I took a look and notice the same thing and sound familiar, Black Turfgrass again ! I won't say the word I said in french.
So I went to the landscaping store to confirmed that and do once again a treatement as I used to kill europeans crafer in last may and kill too black turfgrass (srud control product from Bayer's, I don't like this product because of the impact on bees decline, They decided to replace the bio stuff we use since 5 years by chemical stuff, you know ... big chemical industry have big incentive on the market. So no more bio alternative.
She knows that I have an irrigation system and don't understand why I have this problem. Well I told her, you know the .... Two day restriction and I skipped many schedule base on the weather. She told me, why ?
As she said, did you remember, black turfgrass hate water, so irrigate your grass. Oups, Now I point out my problem, the skipped schedule that I wrote this week on your blog that could be a real problem depending of the weather cases and water restirction So this morning, my dream blow out ! And very confused , should I turn it off.
May be, last week I should think when I asked to my two neighbour on the other side of the street, what's going on their grass and we were thinking it's could be black turgrass invasion because within a week, their grass changed radicatly.
Finally, this morning my wife told me a killing sentence, you know your famous system can do decision on weather broadcast but it's not adapted to water restriction and insect invasion like black turfgrass. Well, may be !
I would say since 3-4 weeks we had a lot of alarm on severe rain and wind in my area and since one week, same alert messages but almost no rain in my area but other had a lot of rain. And presently, big alert message on very strong rain in area about 100km from my house and it's coming in my direction. Also, it's very humid and humidex factor is very high, yesterday is was 39c, so around 102f and don't forget we reach -32f in winter time, so very big variation.
So, what should I do. Till then, I will turn off taking care the weather cases. I think, the algorithme may be change when there is water restriction and probability of insect invation, like black turgrass. I don't know if you heard that kind of need. I know , may be I should use flexible shedule but I can't and I don't want to pay infringement fees.
Thank's for your help
