Hunter Mini-Clik Wired Rain Sensor

Irrigating a landscape during a rainstorm not only results in oversaturated plants and turf, it also wastes water. Hunter's Mini Clik rain sensor provides the simplest, most effective way to prevent sprinklers from running during or after any level of rainfall. It easily installs on any automatic irrigation system. The Mini-Clik stops scheduled irrigation when it detects a pre-set level of rain has fallen. This automatic process ensures landscapes aren't watered during a storm. Once the storm passes, the Mini-Clik allows the controller to resume normal irrigation. Mini-Clik is compatible with all Hunter controllers, and once plugged in, it ensures that a system doesn't water during the rain.

Works just like my old one.
In addressing another customer's question :-- The mounting bracket as pictured, will hinge straight out, giving you a distance of 6 3/4 inches end to end. Should you need additional reach; just splice another piece of metal to the bracket already included. When you splice, put a piece of plastic packaging tape between the two metal pieces to prevent corrosion. (Galvanic Action )

Works Great!
Needed to replace old one (probably 10-15 yrs old) that didn't seem to be working properly. The new one was easy to install and works perfectly! Shuts off the sprinkler system for about a day when rainfall setting is reached.

Very satisfied!!

Quick and easy too install
The only sensor you need to the job right. Quick and easy to install.

Working Perfect!
My old Mini-Clik was at least 10 years old and it worked great until this spring. Did a little troubleshooting from the instructions on your website and determined it needed replaced. Bought one, it is identical to the old one, and wired it up and I'm back in business!

Works like a charm
My son bought one of these for his system and told me how it was as simple as could be. I bought one and installed it the next day. It has worked flawlessly for a year now.

Needed one for a long time
It was an easy installation and it seems to be well made . I have been telling myself that I needed one for ten years and finally installed it and it has not rained since it is in . Hope it works well .

Do you sell the repair kits for this sensor? Kit consists of the plastic cap and cork.
Vince A on May 17, 2012
I have excessively long overhang on the house eves. How long is the extension bracket?
james b on Jul 7, 2014
BEST ANSWER: The straight bracket from the 90 degree to the sensor itself is about 5" long. The ninety degree bracket is about 3" long. You can extend the whole assy out to about 8". Since the straight bracket is held on by a bolt and nut, you could probably attach another piece of metal to the straight bracket and extend out as far as you would need. I think it would be possible.
I have a mini click that is not working. Is there a repair kit? Also wiring is already done. Can I cut and splice and the device will still work? Do I need to just change out the guts?
Scott Heacox on Sep 7, 2013
BEST ANSWER: I didn't find a repair kit online. The item is so basic, it is hard to understand what a kit would contain. It is likely that the moisture sensor is what is bad, but it would be too hard to just replace that. They are meant to wear out over time anyway.

I just cut my old unit out with wire clippers and then attached the new unit. I used water-proof splice caps.
Do you need to do anything to the sensor for winter freezing conditions?
A shopper on Oct 10, 2016
BEST ANSWER: That's a great question. I never even thought about it but I have never done anything and have never had an issue. The device has even survived a few ice storms.
can you adjust the unit to turn off system at a certain amount of rain -eg 1/4 inch 1/2 inch?
Alice C on Sep 29, 2014
BEST ANSWER: Yes, the cap on the sensor is marked at 1/8", 1/4", 1/2", & 3/4". You simply twist the cap and set it to the slot you prefer.
Proper way to Disconnect, Can you just cut wires ?
A shopper on Apr 3, 2014
BEST ANSWER: If yours is a standard installation without a booster pump, the Mini-Clik is wired in series with the common (ground) terminal of the controller and completes the circuit to the sprinkler valves. Under normal conditions, the Mini-Clik switch is closed to complete the circuit and opens (breaking the circuit) when rain is detected. To remove the Mini-Clik, a simple way to do this is to cut the wires and use a wire nut to splice the cut wires together on the controller side, completing the circuit. Hope this helps.
Will this work with a Node 100 controller?
DennisM on Sep 11, 2013
BEST ANSWER: No clue, Dennis. I bought the Hunter Mini-Clik after researching its compatibility with my Rain Bird Controller. Both work fine.

I'd suggest you call the Customer Service folks at Sprinkler Warehouse and have them field your question.
The red alarm sensor light on my Rain-bird controller is on constantly. I can bypass the sensor using the bypass switch, but this defeats the purpose of the sensor. The sensor on the system now is a Hunter 7F19 which I believe is your mini-clik. I suspect the old sensor is bad-does this sound like the answer? Thanks for any help!
gordon L on Apr 10, 2013
BEST ANSWER: Yes, it sounds like your sensor may be bad. To check, disconnect the sensor wires from the terminal and, if the sensor is dry, do a continuity check. The normal position for a sensor should be closed so you should get a continuity reading of 0 or a beep indicating that the switch is functioning. Any other reading means replace the switch.
Why doesn't This unit shut off when its raining?
Richard K on Sep 10, 2012
BEST ANSWER: Mine shuts off only after there has been 1/4" of rainfall. I believe that is the default setting. There is a little adjustment arm on the side if you want it to cut off sooner. I left mine at 1/4" because that is about average for how much water would be delivered by that day's cycle of my sprinkler system. If only 1/16" of an inch of rainfall comes right at the time for the sprinklers to kick on, then my sprinklers still come on and I don't end up in a water deficit from minor morning showers. If you set it on the other end of the spectrum then you're that person who has their sprinklers running during a downpour.
Does this sensor have a normally open contact?
dragonSranch on Mar 6, 2012
BEST ANSWER: Its normally closed when dry. When the absorbent discs in the sensor get wet and expand, the contact opens and prevents a circuit from being completed to the valves.
When connected to rain sensor terminals provided in the controller the controller recognizes an open and stops watering.
sensor appears to have stopped working. Does not shut system off when raining?
Tom M on Oct 13, 2019
BEST ANSWER: Check inside your control box to make sure the rain sensor switch is in the on position. Check the wires from the rain sensor to make sure they are connected to the correct terminals in the control box. Check the wire connections at the rain sensor to make sure they're not corroded or disconnected. Check the rain sensor to see if it is dirty or damaged. Check continuity on the wires to the rain sensor and check that you have power to the rain sensor..
Will this work with a Hunter ACC controller?
Steve S on Apr 18, 2016
BEST ANSWER: I have a Hunter SRC residential/light commercial irrigation controller and I had to replace the rain clip sensor and the new one works fine. It can be adjusted to different rain amounts. Not sure about an ACC controller. I wouldn't think there would be much difference.
Is this sensor the same as the Mini-Clik II sensor which I am replacing?
Tony S on Sep 21, 2013
I'm adding an after market rain sensor to a hunter system installed approx 8 to 9 years ago. I'd like the wireless system can you add more than one sensor?
A shopper on May 21, 2013
BEST ANSWER: Just disconnect the aftermarket rain sensor and install the Hunter wireless....I would put the sensor in a place where you could reach it from the ground as opposed to installing on a rain gutter. They are adjustable so you should adjust them throughout the season.
will this sensor work with my x core controller 6?
A shopper on Nov 26, 2011
BEST ANSWER: The answer is yes, it will work with your x core controller. Page 11 of the manual explains how to wire the device.

If you do not have the manual, it can be downloaded from the Hunter site.
I have the Hunter Mini rain sensor hooked up to my Rain Bird Sprinkler system by professional people. My sprinkler system stopped working for 5 days after the first rain ) although I've already bypassed the rain sensor. Is there something wrong with my rain sensor?
Michelle N on May 21, 2016
BEST ANSWER: It's hard to say...the sensor has an adjustment on it for the amount of before it shuts off. I would start with that and then see what the settings on the receiver are set for. Good luck.
I opened my min-clik and the water absorbing discs fell out in the lawn, I found 8 of them but would like to know how many are supposed to be in the unit?
A shopper on Dec 16, 2012
BEST ANSWER: Have you contacted Hunter? They should be able to easily answer your question.
Can I control two Hunter SVC controllers with just one rain sensor or do I need a rain sensor for each controller? Thanks, Ryan
Ryan M on Jun 24, 2012
BEST ANSWER: I have a problem with this answering yes. I've replaced a Hunter EC Controller with an X-Core controller. After installing the Mini-Click which did not operate, I realized that the common wire on the controllers were wired differently to the Mini-Click in the manuals. The X-Core used the Two terminals for the rain Sensor, the EC cotroller was attached to the common that was connected to the the Valve common. It made a difference. The documentation in the manual mentioned this so you have to be alert on how they are wired currently. If I was doing this I would install an individual rain sensor to each controller. If I wanted to experiment with it, it's easy to test to see if it works correctly. Hope this helps.
How is this installed?
A shopper on Dec 30, 2011
BEST ANSWER: Attached the Mini-Click to the gutter 15 feet or more away from chimney and tree branches. It is approximately 8 feet from the controller. The unit works great. If I have a heavy rain it will block the application. I have overridden the system when I wanted to fertilize using my irrigation system.
Highly recommend the uint and it has been trouble free.
I need to replace the wireless sensor only. Will this sensor work wirelessly with the receiver that I already have?
A shopper on Jul 15, 2011
BEST ANSWER: Sorry, but I bought a wired sensor, not a wire-less. Good luck.

how to hook up for toro timer?
Vince B on Jul 23, 2016
BEST ANSWER: I have a Hunter control and I just mounted the sensor on my garage and ran the wire to the controller and connected the wires (red to R and black to C)
Can I use a rain sensor with a booster pump attached to my system. I guess what I'm really asking is will it also shut of the pump? I don't want the pump running when the valves aren't opening.
Otty W on Apr 24, 2012
BEST ANSWER: In a properly designed irrigation or domestic pump system the switch that controls the operation of the pump responds to pressure. The opening of the valves in a sprinkler system, by relieving pressure in the mainline, ultimately results in the pump switch closing and supplying current to the pump. If your booster pump is activated directly by a relay from the irrigation controller you must ensure that the 24 volt common wire from the irrigation controller to the relay is interrupted by the rain sensor.
My sprinkler service company told me my rain sensor ( a Hunter mini-clik) needed replacing. Instead of paying high service call costs, I decided to replace the sensor myself. Upon looking at my controller (Hunter SRC Plus), the wires from the existing, broken rain sensor have been disconnected by the service company. I do not know which terminals to use to connect the wires. Available open terminals are labled as R and RS. I suspect these are for the rain sensor, but this amateur is asking for advice. The installation sheet that came with the new rain sensor gives diagrams of various controllers, but none have the labels R and RS.
Can anyone offer some advice?

will the mini click II stop the test cycle from running?
A shopper on Jul 17, 2013
I reviewed this item a few days ago online; noted its listed price of $16.94 plus shipping of $8.90.

Checked with local, nearby landscape company that sells Hunter items for price.

Today (now), on your website seeing price is $17.54.

Why is price changing from a few days ago?
