I returned from a week vacation on Sunday to find that Flex didn’t water even though two zones were at 0%. I had a 1-day Rain Delay set for Saturday (Jul 22nd), based on an IFTTT trigger. I’ve had that IFTTT applet setup for at least a year and it’s always worked flawlessly. Both shrubs and grass should have watered on Saturday, and as expected they were skipped due to the forced delay. However, they should have fired on Sunday! On Sunday my scheduled updates indicated that both zones were scheduled, but neither ran!
Please advise on what the hiccup might be. I was able to recover since it happened at the tail end of my trip, but with these temps if it had happened a week ago I would have likely had some dead plants. Thanks.
