[DRIVER] Zooz ZAC36 Titan Water Valve Actuator

I have a rule that runs ~3am every night that refreshes a bunch of devices (incl my Titans), resets some Private Booleans, etc -- it just does some housekeeping to make sure everything's set for the next day.

If you consider doing something similar, just make sure it's time deconflicted with any automatic hub backups that typically run around that same time.

If you use DAC to monitor last activity you can set it to refresh the device for you if needed. [RELEASE] Device Activity Check - Get notifications for "inactive" devices

Otherwise you could just set up a daily rule to run the Refresh command.

Thanks. I went with DAC and it is working great.

Question about leak detection reporting. Recently had to remove the Titan and reinstall it - shutoff valve got too rusty and replaced it - but after reconnecting the Titan, it's constantly in an alarm state and won't stop beeping and flashing a red light. Also thinks that a leak was detected based because my hands were wet when handling it. I set parameter 48 to 0, 49 to 0, 50 to 0, and 51 to 0, and still showing as "leak detected yes" in Apple Home. Any advice on how to clear whatever setting is reporting the leak? Much appreciated.

Oh and param 84 is set to 0 as well

Are you wanting to remove the leak sensor and stop using it?

I would enable the leak sensor again and run a refresh, it should update it to dry. Make sure it is clicked into the power fully, on the newer models you have to push harder than you would think to get it in all the way.

Could also trigger it again with a wet paper towel, then dry it and it should report dry back.

Worst case you could also change the driver to "Virtual Leak Sensor" and then manually change it to "dry". That should push the dry state back over to homekit.

Thanks jtp. I'll try that when I get back home later today. Also, do you know how to manually check the value to see whether the leak detector (from the Titan) is active? I'm solely basing this off of Apple Home and maybe that's the issue and not the actual titan leak detector itself).

What do you mean by active? I dont think there is any status messages it sends to indicate if the leak sensor is connected or not, if unplugged I think it just sends Dry as a response when refreshed.

Thanks - by active, I mean which parameter would be signaling whether the titan is wet or dry?

Parameters are the settings, so none. The Attribute (Current State) of water is what gets the values of wet or dry.

Thanks again, jtp. What ended up working was enabling the leak sensor report (param 84) and a refresh. Thanks!

I have the valve fed into homekit but when in the open state it shows as "Waiting...". It does work to open and close the valve. When in closed state it appears to look normal.

It seems someone else had the same issue with another water valve and fixed but unsure of what needed to be changed in the driver. (Cant post links) Sonoff Zigbee Smart Water Valve thread on the forum.

I found the post I think you are talking about. I do not see there was any other follow up on that "Waiting..." message. The follow up afterwards was about an issue where when the valve was opened the state did not update unless they did a refresh.

I have mine shared to HK via Homebridge and mine looks the same with the Waiting... message in the toggle. No idea what it means.

Thanks for the info, as long as it works I'm happy. I previously has a leaksmart valve set up the same way and it never showed as waiting. I couldn't find any documentation on what homekit expects to receive to clear the waiting message.
