I have been working on a dedicated SmartThings Edge driver for the SONOFF Hydro ONE, SONOFF Hydro ONE Lite and, experimentally, the SONOFF Hydro DUO Zigbee smart water valves. I don’t have these devices, so @Chris74 did the real-world tests for the full Hydro ONE models and provided a massive amount…

[image] Andreas_Roedl: Please test again by setting Manual watering duration to 20 minutes, refresh, and then checking whether the valve stays open beyond 10 minutes. Will test a little later this morning, thanks for your work on this driver, much appreciated!

Hi @Andreas_Roedl , Unfortunately I have to report that it’s still 10 minutes. Requested 14 minutes, but closed after 10: [Screenshot_20260703_142028_SmartThings] Settings: [Screenshot_20260703_142322_SmartThings]

Well … I think it’s time for some logs. I had a guy who was providing me logs, but he’s on vacation or something. Anyway. New version: 2026-07-03T19:54 Added a keepalive to override the firmware timeout. Make sure that the latest version is installed. Keep Timed watering mode = driver timer. Set…

No worries, I can provide logs for you too, but I just left for a short holiday until Tuesday. This isn’t urgent by any means, but I’ll let you know how my additional testing goes. Hope you have a good weekend and your temperatures are cooler.

Hi @Andreas_Roedl Ermmmm… Since the driver updated to …07-03… it has failed to operate my valve at all, just not responsive :man_shrugging:t3: Re-added device but no joy, I’ve had to resort to ST stock :frowning:

Sorry about that. That version introduced an regression while trying to work around the 10-minute timeout, and that could make the valve stop responding. I’ve pulled that build and replaced it with a newer one (2026-07-04T19:41), which rolls back the risky changes and is meant to restore reliable ba…

To keep the logs useful, please capture only the driver log around one clean test. Before testing (important): Make sure that the latest version is installed: 2026-07-05T00:56 Open the device settings in SmartThings. Enable Debug logging. Set Manual watering duration to 60. Make sure Timed wateri…

Thanks @Andreas_Roedl , 2026-07-05T00:56 installed and back to running with it now :+1: Not using duration specifically at present but watching the discussion with interest… Thanks again

Hi @Andreas_Roedl , I’m still waiting for SmartThings to update the driver on my end. I’m still on 2026-07-04T20:14:16. I noticed that on this version that if I selected any value with timed watering that the presentation showed the valve open and on, but it actually didn’t open. Even though I’m …
