Are you looking for a new device? Which is Z wave? If so, we need to know which country you are in because the frequencies do vary.
Are you looking for an edge Driver for an existing orbit 27087? I know @johnconstantelo used to have some of these devices, he may be able to share what he’s doing with them if he still has them running.
For what it’s worth, which may not be much, I’ve been quite pleased with the Orbit bhyve device. It’s WiFi and you get partial integration through Alexa routines (not smartthings routines), but we’ve had ours for two years and it’s been reliable and works well. I do understand that may not be what you’re looking for, though.
I used to have a DTH for that device, but the timer portion of the valve never had zigbee clusters exposed (that I could see). I ended up using a setting to “spoof” the 10 minute auto timer.
I did eventually rejoin this to the hub as a Zigbee Switch driver, and then changed it to a Zigbee Valve. I’d don’t know if the mobile app will allow you do that anymore, but the new SmartThings Advanced Web App will let you change the driver to a Zigbee valve if you have the driver installed on your hub:
There are no timer capabilities obviously, so you’d need to develop a Routine or use SharpTools, depending upon your use case.
My valve finally broke and I replaced it with a WOOX Irrigation Valve I got shipped over from the UK (not bad pricing either). It’s been working great, and all I had to do was get a little creative with the connectors to convert to US specs.
