I am looking to make a simple float switch sensor that I can mount on an aquarium to send alerts if the water level is too high. I have a commercial automatic top-off system that won't trigger alerts.
I don't mind building it, but I would like the power and radio to be already built, and just allow me to hook up the float switch. I have the float switch already, i just need somthing to hook it up to that can talk to the hubitat.
Go Control used to have this contact sensor that lets you hook up your own switch. But is doesn't seem to be available anymore. https://www.gocontrol.com/manuals/WADWAZ-1-Install.pdf
Does anyone know of anything simliar?
An option that should work would be to setup a water leak sensor that has external leads at the level that you want to be warned. The sensor could be kept above the water level and the leads could be fastened at the level you are looking for a warning.
I have something similar setup under my sink where I have a bucket in place to catch leaks from a filter. When it does leak, it starts filling the bucket, and above a certain level, I get a warning and I can empty it.
I am using Aquara Water leak sensors for this, but they are non-standard Zigbee so I have them setup on a separate hub with dedicated repeaters. There are likely other options available.
THanks @Sebastien it's a good idea. The problem is the aquarium is susceptible to splashes as I do maintenance so the external leads tend to trigger false alarms as water splashes around. I have something similar setup in my ejector pit in the basement, and I ofter get false alarms as the washer empties itself. I have to keep it up pretty high and by that point, it's kinds late.
I have the same gocontrol contact and use it for detecting if my aquarium water holding tank level is low. It turns on a switch attached to a solenoid valve to start filling the tank in 2 minutes on, 15 minutes off interval so I don't use up all the RO water in the under sink tank.
I do have a manual float valve installed as backup in case the contact sensor gets stuck on fill mode.
And, for completeness, here’s a leak sensor with easily accessed terminals that can be used in the exact same way:
Aqara Water Leak Sensor, Requires AQARA HUB, Wireless Water Leak Detector, Wireless Mini Flood Detector for Alarm System and Smart Home Automation, for Kitchen Bathroom Basement, Works with IFTTT
After I posted this I went and looked at a water sensor I had purchased for my ejector pit opend it up and there are two dry sensors available as well. I bet this would work too.
I use a Third Reality water leak sensor with leads connected to the external screw contacts to a micro switch with a jar hung from it to alert low level in my water softener salt tank. A nice plus is that it also has an audible alarm. I actually have ten of them scattered about performing traditional water leak sensing. ZigBee, very long battery life. Have never had connection issues. https://www.amazon.com/THIRDREALITY-Detection-Notifications-Compatible-SmartThings/dp/B09GYFN8VL?th=1
