Hi,
I really need some ideas to find a solution for my new renovated shower, I have replaced the tub with a walk in shower, however with this new setup the shower drainage is lower than the main drainage tube, so I need a pump to evacuate the water in the shower, I have bought the pump, but the issue now how to activate it when the water flows inside the drainage.
I have bought a water flow sensor but it didn’t work at all, I couldn’t find a good reliable brand to use.
I have smarthings hub controlling all my home security system and automation.
Is the shower powered or gravity fed - if powered maybe one of these (or similar) on the power line:
If shower > 0w pump on, = 0w pump off… Initial power report may not be immediate enough for you though - although no slower (probably quicker actually) than wet/dry report from a leak sessor
Thank you for your suggestion, unfortunately the shower is operating by the natural water pressurised network, no power at all to detect and used as trigger for the pump
You need to find something with your shower design that changes state when it’s in use. There’s other types of flow sensors, pressure sensor and water contact sensors that you could uss, but not knowing exactly how it’s designed makes it very hard to give you good advice. For example will the pump always have water in it? If not will it burn out the pump. What type of pump is it. Information like his is need to make the correct choice. You can always just put a smart button in the shower and press it when you see the drain filling up. Anything is possible.
Install a pressure switch between the shower control valve and the shower head. If there is pressure it means the shower is turned on. Connect the pressure switch to smart device with with external switch contacts. Could be a ZigBee or WiFi smart module or a Zooz Zen 16 or 17 (US Z-Wave).
@shady_mostafa The ZEN16 or ZEN17 are good choices & work very well. If you’re looking for a Z-Wave device that’s much, much smaller–and almost ideal for this use case–you might consider the recently released Zooz ZEN58 800LR (or maybe its cousin, the ZEN57 800LR). Both are about the size of a postage stamp (!) and differ mainly in the voltage needed to run the device.
