Success!…Re-programmed it, then I use the Run Once running the station for 2 secs and works fine…The only drawback is that the phone app do not have a sensor status indication, so I have to use the webapp. For now this works, my next update will be analyzing the circuitry to see how can a separate sensor be added/programmed.
Just chequed via PC web, version 2.04. hmmmm, I just bought this unit 2-3 wks ago, I expected the newer SW installed. This will be my 1st on how to update firmware on this unit. I will report the outcome. Thanks!
I am using the exact same transformer and I did not connect the green-gnd wire. The importance of the ground is for safety reasons and specifically when plugging/unplugging near wet/damp areas, but it will not damage the unit. It is a fail-safe, ie, if there is an open on the neutral wire, the gnd provides a path for the current to go to gnd vs through you.
Well, hardware wise it works, ie when the door is open the rain sensor indicates is on, when the door is close no rain. With the door close, ie no rain, going to run program once and setting the station for 2-3 seconds closes the relay. Here is now the problem: if rain has been detected, ie garage door is open, this inhibits the “run once program” to turn on any station. This kind of doesn’t make sense, I should be able to run any program once/manually regardless of the rain sensor, ex: to check valves/sprinkler heads even after the rain has stopped, a firmware change will be required. 🙁 :-(.
I have a notional design to accomplish this, see attached. I am not planning to use for now the rain sensor, so I will be using it to detect if the garage is open or close. Running the once program for 2 secs for the specific station should activate the relay no different than pressing the close/open button. The only potential problem is if the door is left open and a sprinkler program is about to run, but in my case, I water at night so the likelihood of this coincidence is low.
Ray, sorry for the delayed response…Took unit out today and here are the picture of the contacts, they look good. Took card out, put it together and turned it on, now it works w/o the SD card… Wondering if this is an intermittent problem, contacts on the inside of the slot itself? If you have any continuity or voltage checks you can share if the problem re-appears, I will appreciate it (I am an electronics eng). For now I go back to my eng and tech basis: “if it ain’t broken, don’t fix it” 🙂
Ray, I went ahead and plugged the unit back in, now is working. I am assuming it had to do the first time with the sequence, ie I had not configure the unit for expansion, while connected changed the config, never unplugged it all this time. Unplugging it and plugging made have made the trick. Sorry for the mislead. Awesome product, I was going to buy irrigation caddy…
I have the OS 2.1u just delivered this wk and I am having this same problem. I got to pass from detecting uSD to network connections by inserting a uSD. I know in previous post of this forum it says it should not be required, so not sure if this is a result of a new firmware update. After it connects to the network, I took the SD out, but on power loss, it will look for the uSD again, so ended leaving it in there.
