I know my old ESP-SMT weather sensor will not communicate the ambient weather info it gathers to the Gen3 controller. However I’m wondering if I can use it as JUST a rain sensor. Anyone have luck with this? I’ve had my Gen3 installed for a month now with a Flex Daily schedule and it has been doing it’s job with regards to weather adjustments up until today.
I had an issue this morning with a early morning rainstorm (0.26in between 0230-0400 this morning). I had thought the weather plus settings (skip watering with 0.125in of rain) would skip this morning’s watering. The schedule shows that watering was going to start at 0214AM, forecasts (weather underground) showed expected rainfall overnight (~0.3in). The storm was loud enough to wake me up, so I checked the system and it was in the middle of a watering cycle that I had to stop manually. Had I not woken up the system would have run through it’s scheduled watering cycle regardless of the on-going storm.
Based on this, I was hoping to use the old ESP-SMT as only a rain sensor to cover this use case. I’m assuming that the logic adjustments for weather happened in a small window where it did not adjust based on my rain skip settings in weather plus? An attached rain sensor would have stopped the watering cycle autonomously in this case correct?
Is my understanding of Rain Skip flawed? Does Flex Daily not take that setting into account? Moisture balance for the Zones running in the cycle show about 25% moisture balance prior to running, so I understand why the system would water those zones, but the forecast showing rain should have rescheduled/skipped this cycle correct?
