> 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 idea is most definitely ok. 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. 🙂

> 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, the contactor is desoldered… soldered wires, each wire in a separate thermoplastic sleeve with glue, the whole in an additional thermoplastic sleeve with glue. 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…
