Thanks for double checking this.
I just re-ran two tests with the following results:
Ran a station for 20 seconds and manually shorted the sensor 25 times for each firmware:
2.1.9(0) – recorded 25 pulses
2.1.9(3) – recorded 21 pulses
Ran a station for 1 minute and manually shorted the sensor 101 times for each firmware:
2.1.9(0) – recorded 101 pulses
2.1.9(3) – recorded 19 pulses
See attachment for OpenSprinkler log results for each test.
Also, I am using stock firmwares for both versions.
