I just installed my first Red series 2-1 dimmer, VZW31, and I’m seeing some odd behavior. When multiple taps are queued up (like an impatient human pushing a button repeatedly) the switch “crashes” and reboots itself. This happens on up or down presses of the main paddle. Is newer firmware available? Do I have a defective switch? Overall the switch works well and this is a relatively minor quibble.
More details…
Hubitat C7
Neutral present
Configured as dimmer
Load is five LED bulbs in a chandelier
Hubitat shows the firmware version of the switch to be 1.2
I will be installing a second Red 2-1 as a “remote control” for this switch (no load, smart switch only) soon.
That is not normal behavior and is not a firmware bug. I would recommend re-checking your wiring to ensure you have line and neutral properly connected to the switch line and neutral terminals.
1,02 (displayed by some hubs as 1.2) is the current firmware.
Agree w/ @PJF that this isn’t likely a firmware issue. I tested on a Red on ST by pressing the up paddle about 50x as fast as I could, and the switch did not reboot. Theoretically, that could be a driver issue, but AFAIK, no one else has reported this as an issue here.
I am adjusting your title to more accurately describe your issue.
Problem has been resolved - the neutral wire (and possibly the line and load) was a little too far into the hole and the jacket on the wire was causing a weak connection. I reseated all three wires (neutral, line, load) and the problem disappeared. All wires were in the correct places, BTW.
The fault conditions changed slightly after my post. I tested it the next day and it would no longer re-boot on multiple taps. Odd, but I wasn’t unhappy. Then I discovered that every time I changed the “on” brightness of the LED to 100% the switch would reboot every time the load was turned on. Correcting the wires fixed that problem. It is now 100% reliable and I’m very happy with it.
