Most rain sensors must collect a certain amount of precipitation before a switch is activated, which stops the irrigation process on the controller and shuts down the system. Until this point, the system continues to use water unnecessarily. This is particularly problematic for environmentally conscious municipal, commercial and private users. The Hunter Rain-Clik and the Wireless Rain-Clik with integrated quick-response technology can trigger a switching process immediately after precipitation begins. The Rain-Clik can be attached to an eaves or any smooth vertical surface such as a wall or fence.
Compatible with all OpenSprinkler products. Simply connect to Gnd and Sn1 or Sn2 on the OpenSprinkler 3.0 / 3.2. For OSPi to the Rain Sensor connection. Since this is an “opener” from an electrical point of view, not only “Rain Sensor” must be activated in the OpenSprinkler settings, but the “Normally Open” option must also be OFF.
When using with the A2D: Connect the Rain-Clik to Sn1/Sn2 and VIN (+5V) directly on the A2D output and set the pot to the middle position. If that doesn't work, then connect the Rain-Clik directly to the OpenSprinkler (together with the A2D) to GND+SN1 (or SN2) and bridge the GND+SN1 (or SN2) connections with a short cable on the A2D.
NEVER CONNECT TO COM! There is 24VAC alternating voltage at the COM, which can destroy the signal input!
To test on the OpenSprinkler there is the test button, press it for at least 30s as the display reacts slowly.
To test on the measuring device: So dry = contact connected, approx. 0.01 Ohm; Wet=contact open, infinite ohms. Pressing the button opens the contact.

Bonjour!
The power adapter has a function on the OSPi 1.52 version that is now available, and the A2D adapter is turned on to the LED rouge allumée, and consider qu’il y a toujours contact.
Pourtant, le capteur a été testé à l'ohmmètre, il indique bien un contact par défaut, et l'absence de contact quand on appuie sur le bouton de test.
The black cable is tested on SN1 and SN2 on the A2D, and the red cable on 5V, and the potentiometer is configured in all possible ways…
The 'A2D adapter works well, it is tested with two humidity sensors, without problems.

Techniquement, il existe deux versions du capteur de pluie, l'une ne fonctionne qu'avec l'astuce décrite ci-dessous.
Here's a new description of the page in the boutique:
In case of utilization with the A2D: connect the Rain-Clik to Sn1/Sn2 and VIN (+5V) directly to the range of the A2D and regulate the pot on the central position. If you move along, then connect the Rain-Clik directly to the OpenSprinkler (in the same time as the A2D) to GND+SN1 (or SN2) and connect the connections GND+SN1 (or SN2) with a cable court on the A2D.
