Best Water Leak Sensors. I bought some Sonoff SNZB-05P water leak sensors that come with the braided cable and I tested one out before setting up all of them. Terrible experience as it would work to go from dry to wet but then it wouldn't go back to dry. After removing the device and adding it again the experience with the braided cable was even worse. I put one single drop onto a quarter-sized part of the cable. It worked going to wet status but after drying it out, blow drying it, and waiting 16 hours there were no activity status updates from the device. Needless to say I am returning them …

Once Home Assistant’s HomeKit Bridge shares it, this device reaches Apple Home as a HomeKit accessory behind your Home Assistant bridge, so ReReHome shows and controls it like any other.
