Hey,
I have one of these ENERWAVE Z-Wave Plus Relay RSM1. It was working reliably since 2019 with my smartthings. In May I switched over to hubitat C8 pro and after issues with setup - see here - ENERWAVE Z-Wave Plus Relay RSM1
However after 3 months or so, the unit began working only intermittently and now I cannot control it at all. Z-wave repair doesn't work for this device. I am running the latest firmware and a reboot of the hub does not help anymore. Range is not an issue.
Unless there is a simple solution I would like to replace it. Is there a comparable relay that is known to work well with hubitat? I will add that this is installed in a porch light, that is a real pain to remove so I would prefer to replace it with something reliable.
Thanks everyone
I've been using the Qubino Flush Relay 2 for at least as long but it's a Dual Relay version. For many applications it's similar enough. The major difference is that it's not a dry contact relay. It shares Line. (Line is hard wired to one side of the pair of relays. A load is connected between the Qubino and Neutral.)
If that works for you, then it's a decent little device, same physical size.
They do make a Flush 1 Relay, but it also shares Line. A third product from then is the Flush 1D (D for Dry) but I haven't seen availability for either in a while.
Shelly makes a WiFi version and Hubitat has built-in drivers for yet another option 
I also have a RSM2 working for a long time.
Still going strong.
Another replacement is the zwave Zooz Zen51. (I have a few of these)
It has a few more features that the Enerwave doesn't have, and it's around the same size.
Thanks everyone. Went with a Shelly 1pm Zwave Plus. Working great so far.
