Thanks for the clue- I now have it fixed. In this version- the firmware has rainsense configured for pin a1 and it seems the rain sense connector was just wired to a stub out hole in the Pcb. Once I added a jumper from that hole to a1 everything works great.

Thanks – That is the way I assumed it would work.

If the unit is set to “normally closed” – it is on constant rain delay. Changing the state of the terminals has no impact. Similarly, Having it set to “normally open” the controller thinks it is always sunny.

To summarize, it seems as the controller is not detecting a closed circuit across the terminals.

Any ideas on where to look?

Thanks!

I used your GUI firmware updater. Everything seemed to go smoothly. Any suggestions on the hardware issue? Am I correct in assuming that a jumper wire across the rain sensor terminals should emulate a normally closed sensor?

One more odd thing. When I first added the rain sensor and had issues – I was on firmware version 1.8.2. I thought I would upgrade to the latest before asking for help. I just noticed, however, on version 1.8.3, if I try to add an interval program, the sprinkler basically locks up.

The only solution which seemed to work was to go back to 1.8.2 (which I did) at which time everything worked as expected (with the exception of the rain sensor).

Not sure any of this is related to my rain sensor problem, but thought I would add it as additional information. I am now back on software version 1.8.2

Yes – I did refresh the browser. I was also looking at the LCD display.

Now I understand – Thanks for the quick response!
