The Aeotec Water Sensor 6 has disappeared from the stores. You can only find the Aeotec Lasso Sensor and the Aeotec Water Sensor Dock. On the Aeotec website, this sensor is listed as Discontinued Product.
Does anyone know a sensor similar to the Aeotec Lasso Sensor? Not point-based, but one that guards a larger area?
I have been using an Aqara zigbee Leak Sensor with the Aeotec Lasso Sensor. I connected the lasso to the bottom screws, I had to lengthen the leads so they would reach. You could also use the Fibaro zwave leak sensor and connect the leads to the internal connector.
