I also recently purchased some of the EcoLink Flood and Freeze sensors. Got them included, setup HSM alerts and almost gave myself a heart attack last night. I placed one of these sensors in my hot water heater pan (In the attic) and around midnight last night while sound asleep, HSM did exactly what I asked it to do... Siren going off, lights flashing, phone buzzing, except there was no water leak (Except possibly in my pants =).
I think the generic driver is treating freeze events as "wet", because last night it got pretty cold outside, which is unusual for the area I live in. Is there any way to handle freeze and wet events separately or is there a different driver I should be using?
Sorry for my ignorance, I am very new to Hubitat.
Ever get anywhere with controlling the 2 SPST switches in the Intermatic CA3750? (I want to use it to control spa equipment but need both switches controlled independently. )
This is an old zwave device that does not report its status back automatically to the controller.
The driver to use is Generic Zwave Dimmer. And then, use the built in Zwave Poller app to poll this switch so the hub keeps track of the current status of the dimmer.
Also, without polling, the dimmer will not be controlled well by voice assistants like Alexa. Three final things:
- Click Configure each time you change drivers.
- The “Smart” drivers are for zwave+ devices.
- Consider replacing it with a zwave+ device like a Zooz or iNovelli dimmer.
Ok, we're going to get this working. Let's try this instead:
- Create a virtual dimmer and expose that to the Amazon Echo Skill on Hubitat.
- Setup the built-in Mirror app, so that the real Intermatic dimmer mirrors the virtual dimmer.
- Turn on debug logging for both the virtual and Intermatic dimmer.
- Keep a log page open.
Use Alexa to control the virtual dimmer. The real dimmer should change as well. In either event, post a screenshot of the logs page.
Glad it's working!
Please continue using z-wave poller for that dimmer. It is necessary for this setup to work .....
No need to feel a bit silly or embarrassed about it. This is something I had to discover the hard way, as well. Any time you're moving to a new platform, there's a little bit of a learning curve.
I've had to rely on the awesome Hubitat Community to help me figure out a good few simple little things I had overlooked. I don't think anyone here is going to shame you at all for having to figure something out. 
I have one device that is actually on the list of compatible devices but the built in driver does not work properly. Its the ZXT-600 by Remotec. The driver works for control but you are unable to program it from the built in driver. I actually emailed support about this not too long ago, but no response just yet. Here is the workaround from myself and others. Remotec ZXT-600 Issues with Built-In Driver - #16 by chad.andrews
Separate question, is there a Zigbee thread for missing or incomplete drivers? Like to have something for my StelPro Orleans Heaters (Zigbee Ki).
