I’m thinking about just getting 2 x 14295’s Z-Wave Plus to replace both the 12729’s in my 3 way circuits and just use the them on a single circuit as my other 12729’s on single circuits have been working ok. Hopefully that trend will continue.
Depending upon your use of other devices, like zigbee sensors, consider GE’s Zigbee version of the dimmer to build up your zigbee mesh. I’ve slowly replaced my Iris wall plugs with GE zigbee switches, and I’m very, very happy with reliability and performance. Not a single problem in years, and they report power consumption (watts) too. Personally I think they’re faster than the zwave plus version (I have those too).
Models are 45857GE (dimmer) and 45856GE (switch)
Some of the reporting issues were related to a patent at the time held by Lutron/Leviton (I can’t remember which one), which now apparently isn’t an issue (again, just from some quick reading). There are a few discussions about that from a couple years back, but ST did something on the back end (as other companies did) to work around it.
I was told at one time that the old switches that were experiencing problems actually had an issue with heat dissipation. GE’s newer switches (past the 4xxxx series) started to come with slots/vents at the top and bottom of the case. I had an older 4xxxx series switch laying around, so I cut my own to see if that actually did anything. That switch is still running great in my garage almost 2 years later.
I actually don’t recommend anyone doing that though, at least while the device is on live power
So I swapped out both my 12727’s in each of my 3 way circuits for 14295’s using the Z Wave Replace option and now ST updates just as expected. No matter which switch is used to turn the light on or off, ST updates in about 2 seconds. I left the add-on 12728’s as is.
