The only reason I can see for why the OP would like to retain existing water detectors and add smart capability would be if the original sensors are costly/ultra reliable.
Otherwise then yeah, why not rip out and replace with an all-in-one smart sensor for a couple of quid.
I'll probably run dc power to mine though. Not a fan of battery powered devices.
yes, I didn't follow you that the water sensor you are discussing can contact the Hubitat directly.
That could work, however I am looking to replace my Sensaphone. Currently there are 4 inputs wired to a central location. Two NO motion sensors, and 2 NO water sensors. Changing out the Sensaphone for another device that can contact the Hubitat would be the best solution for my setup. Thanks for all your responses.
If you want to retain everything, just use four leak sensors as dry contact sensors, they will report their state to Hubitat in place of the Sensaphone. So in Hubitat, you would label two of them as leak sensors, and two of them as motion sensors.
As I already mentioned above your best option is/will be a low voltage version of Shelly I4 device. As of now (quick check) Amazon has only Line Voltage version WiFi version:

This also could be used but will need either set of 4 Relays (or if you are OK with DIY electronics, high voltage fat transistors or optocouplers.
There is definitely low voltage version and even with one with ZWave radio.
Of course, there is a custom driver for the WiFi Shelly I4 device:

Just in case here is a link for Shelly I4 DC Device WiFi:

There are an overwhelming number of water sensors. Could you recommend a couple?
Definitely check out the Konnected Pro, I installed one at my daughters house 2 years ago, its working flawlessly without touching it since installation.
Do you have an automated shut off valve for your water main?
No, not needed for my current setup.
You think that is better solution than just using four $5 dry contact leak sensors?
Yes.
To begin with, this is ONE device instead of 4.
Second - this one is powered from low voltage PS, not a battery.
Third - Leak Sensor input is very high impedance input. It easily could be triggered by noise on the attached wires. If anything, I would recommend a Contact Sensor instead. Electrically this will be much better.
Also from the OP message it is not clear if output(s) from the existing sensors are true dry contacts or there is some voltage on a wires. If outputs are true dry contacts they could be directly connected to the inputs. However if there is some voltage present a direct connection to the Contact/Leak sensors could be distractive. I4 device could be OK if powered by the same voltage. But it could be wise to use some sort of voltage translators such as Opto-couplers, Transistors or just a Relays.
This device is either configured as dry contacts or temp sensors. It can we replaced with another device with dry contacts.
This is the device
The diagrams make it clear it just trips a relay with NO or NC.
OK. This true dry contact output. It could be connected directly to the input of whatever IO device of choice. If I4 will be used it could be powered from the same power supply.
I am not a fan of batteries if that can be avoided. My Sensaphone is almost 30 years old. I opted not to use any battery backups, becuse of our solid power grid. I could count on one hand the number of times a power outage has lasted more than 2 hours in the past 40 years. It has been a solid setup, but circumstances have cause me to upgrade.
If you can solder, you can get a 3v DC transformer and power the sensors that way by soldering wires onto the battery terminals. I would also just solder wires onto the dry contact probes to attach them to the relays, instead of cutting the probe off.
A 3V 1Amp transformer is only $6 on Amazon, which should power all four of them.
Mine has just arrived, thanks for that.
A fiver? Absolutely perfect!
Hi, is this still working well. What's the verdict. Also which driver are you using?
Yes, perfection.
Built in driver. paired in seconds.
The shelly wave i4 DC is working for me, Thanks to everyone for their suggestions!
