Any recommendations for low voltage relay?

Hello,
wondering if anyone can recommend a low voltage relay for me.
my use case: doorbell cam is powered by the doorbell relay. relay is in the basement. cam is getting old (I think) and I have to reboot it once a week. cannot reboot from the app, and I have to walk down to the basement, grab a screwdriver and disconnect the bell relay and reconnect.
looking for a hubitat compatible relay so I can do this from the dashboard.
I don't really want to replace this cam, it is compatible with blue iris and these seem hard to find. I'll run with it until its last blip.
I'm looking at devices like this but I can't figure out if they'll work with hubitat:

Thanks

Most of the Zooz stuff will work with Hubitat, either natively with default drivers or through custom ones on certain devices.

That being said, what if you cycled power going to your doorbell transformer instead? In other words, put the doorbell transformer on a 120VAC relay or smart switch.

good suggestion, would be easier, I'll have to look at how it's powered. it's just on the side of the furnace I didn't think about that.
thanks

Zooz Zen16 or Zen17 can be powered by 12-24VAC. That may allow the transformer output to power the relay. Just another option.

Optionally, you can upgrade the transformer if you decide you to go with a smart plug.

Thank you all. I didn't even know they made plugin trasnformers like that :slight_smile: i'm old school

Just flip the breaker for the circuit.

does the camera have a webpage? maybe a post URL can get the camera to reboot. I'll assume the camera is running Linux?

It's a LaView ONE Halo HD
they have a website but no mention of this one. I don't remember ever using an api with it. I'm actually surprised it's lasted this long

I use several of those Zigbee relays like the MHCOZY you posted. They are available under many names, but they are all the same. Thy work great with the built-in Generic Zigbee Multi-Endpoint Switch driver. I highly recommend them. I have never had one drop from the network or fail to respond to a command.

I have a 4 gang that runs my heating zones, by sending power to the zone valves. Runs off of the 24V AC furnace power supply using the input terminal.

I have a 4 gang that runs my fan hood three speed fan over my stove (made it smart). It runs from a 12V DC power supply, using the input terminals.

I have a 4 gang that I used to convert a dumb tower fan to Zigbee. I runs off of a 5V DC usb power brick, using the usb input.

The input power options are what make these really flexible. They all have an RF remote receiver built in as well, some you can buy with the keychain remotes. The remote works even when connected with Zigbee, as another control option. You can buy one without the remote, then buy the remote on Ali Express for like a $1.50.

Edit: I don't have any one channel, but I imagine that will work fine with just the Generic Zigbee Switch driver. The multi-endpoint driver would probably create a parent device and a single child device for the one relay.

This is the RF antenna:

And Remote (there are instructions with the relay how to pair the remote):

While all this is true, and they can work “great”, be aware that the cheap Songle relays in these things are known to go bad.

I had one that started chattering after about a year of use. And would open/close my GDO unexpectedly.

Here’s that thread:

The ZEN58 works on Hubitat: How to Add Your ZEN58 Low Voltage XS Relay to Hubitat - Zooz Support Center

You could power it from the doorbell transformer AND run the + side of the wire going to the doorbell through the in/out on the ZEN58 to be able to cut power and reboot it.

Seems like a perfectly easy solution to me.

I've had a bunch of those boards now for years, I even have additional boards for irrigation I didn't mention.

Only one has "failed", in that the AC/DC input died, however the 5V usb input still works so I am still using that board. I really have seen no issues with the Songle relays, even one that is kept constantly engaged for months at a time.
