It would be brilliant for Sonoff to release a zigbee rains sensor to be used along with the zigbee **SWV** Sonoff Water Valve, currently using an altered zigbee rain sensor **SNZB-05P** - on the Ewelink app , it would be great to add a weather forecast into a set Trigger - so if rain is predicted etc. ---

So I used a standard **SNZB-05P** connected with its cable directly to a Rain Drop Module - connected to **Ewelink** - and automated it to disable my scenes controlling my **SWV** and it works 100% - the rain drop module stands at an angle - [@Staff-of-SONOFF](https://forum.ewelink.cc/groups/staff-of-sonoff) @eWeLink ![WhatsApp Image 2025-02-24 at 15.34.32_ec054d2b](https://europe1.discourse-cdn.com/flex005/uploads/ewelinkforum/original/2X/1/1e3a5060075292ac77e662494912d6629253da32.jpeg) ---

Lovely work! I would add some hot glue on the screws for water resistance. ---

Its very simple , **SNZB-05P** Water Leak Sensor connected with a **WLDC200** Water Leak Sensor Cable - cut the end of the cable off - solder to the Rain Drop Module - preferable one with pins so that you can solder the cable inside the housing and keep the water leak sensor cable form getting wet - put in a water tight housing - angle it so that drops run of the front of the module and setup in Ewelink ---

The screws and spacers of the rain drop module are sealed with glue and the screws of the box does not penetrate the housing + the lid has a rubber seal ---

Maybe it is possible to solder the wires from the RainDrop module directly to the SNZB-05P without the WLDC200? ---

it should be possible , I just went with the cable - it was the least invasive way of doing some tests - I believe the connectors on the **SNZB-05P** are gold plated to make sure it does not rust - so take that into consideration ---

Although personally I would rather not destroy the cable permanently, but make a USB end, but that’s a detail. However, generally using 05P is rather a slightly more expensive option compared to the regular DW2. I use both DW2RF and DW2WIFI, where I desoldered the contact and soldered the cable terminated for my needs with a water level sensor. But the principle of operation is the same, provided that the water/humidity sensor is a reed relay type with an open/closed state. Of course, it doesn’t look so nice in ewelink when it writes “door” next to the sensor and no zigbee. 🙂 [![](https://europe1.discourse-cdn.com/flex005/uploads/ewelinkforum/original/2X/d/dedb7fc8e90c19b738edcd3df4a94d85c10649c2.jpeg) ](https://europe1.discourse-cdn.com/flex005/uploads/ewelinkforum/original/2X/d/dedb7fc8e90c19b738edcd3df4a94d85c10649c2.jpeg) > [@DIY Single-level single-function water sensor](https://forum.ewelink.cc/t/diy-single-level-single-function-water-sensor/39612): > > A simple floating magnet and contactor($3.14) module connected via a two-wire 0.5mm cable to Sonoff DW2-RF (open version only).

In DW2-RF, a hole is cut for the cable. The whole thing works on the principle that when the water level drops below a certain point, the sensor is opened and the DW2-RF sends a signal… ---

Also a good idea , went purely for the **SNZB-05P** Leak Sensor - because of the water animation in the eWelink app + how it looks inside eWelink Web - only down side is the action comes through as leaking/Leak detected etc. - but its ok - ![image](https://europe1.discourse-cdn.com/flex005/uploads/ewelinkforum/original/2X/b/b82cb5c4a75193d0277dea369ff62dda863033d2.png) (upload://7PDcYwYkvUL8JCGDuEROr8E4gcF.jpeg) ![WhatsApp Image 2025-02-27 at 12.56.55_2779afbb](https://europe1.discourse-cdn.com/flex005/uploads/ewelinkforum/original/2X/3/36e55f1206a4337f946b205080345f17d737e371.jpeg) ---

I used this sensor in a pair with a zgb door opening sensor to detect overheating of a solid fuel boiler. The boiler has a safety group, an air valve. When the temperature is too high, and therefore the pressure in the heating system is increased, then water splashes out through the air valve. I placed this sensor in such a way that water splashes would hit it. ---
