I know from painful experience the "suddenly" word is often anything but (i.e., usually given enough thought one can trace something that DID change) but I find myself "suddenly" having awful problems with z-wave and I'm at wits end, and looking for advice please.
Basically, a couple weeks ago the OPII z-wave performance became very erratic. No code changes or anything new or different - just that z-wave no longer works reliably. It went from 99% accurate to maybe 75% accurate: events and inputs trigger just fine from what I can see in the "Status/Control" pane of PCAccess - flags and timers get set, inputs are received, etc. but z-wave is just not getting out.
When I do a refresh download ("Write to Controller...") of the whole shebang, things work again for a day or two... and then z-wave fails again.
Interestingly enough, when I send z-wave commands directly from the Vizia RF+ stick using the Leviton Vizia RF + Installer Tool utility, everything is received and works fine.
I have had lousy experience with the Leviton Vizia RF+ serial interface module and I've replaced this critical component three times already... but at $135 a pop, plus a few hours relearning all of my nodes (I have 61 z-wave devices), this gets old. All of my z-wave devices are the Leviton VRM10/VRI06 - in other words a few years old and do not have NWI or the more "reliable" feature-set of the current z-wave code. But just as I don't want to keep replacing the Vizia RF+ serial module, I also don't want to run around replacing every dimmer in the house.
So far, because commands wok fine from the Leviton RF stick, that I keep replacing RF+ serial interface modules, and that things "work" fine for a day or two when I do a refresh download of the OPII configuration from PCA, I'm suspecting that something is going bad with the OPII serial port perhaps? Just an uninformed hunch.
I've been looking at the Homeseer Z-NET Remote Z-Wave Interface and wondering if this is more reliable than the Leviton Vizia RF+ serial interface??
I do have Homeseer running behind the OPII, but to-date I am using it only for things the OPII cannot do natively, such as play .wav files on events, and manage e-mail actions. I'm thinking (especially since Leviton bailed on HAI) that I start to move all of my event code to Homeseer and just use the OPII as an I/O board and touchscreen controller.
If anyone has thoughts based on what I've shared, I would be very grateful.
