I don't think the LR version changed anything functionality-wise according to their changelog. This is still the driver I'm using, though I don't remember if I have any of the new ones...
No reason to update something that works as intended.
I have a ZEN34 that operates a gate.
I also use several ZEN73 toggle switches to operate the gate.
The driver for the ZEN73 that @jtp10181 wrote has the capability to SetParameters in Custom Command.
I have the toggle's led turn on when the gate is open-it's proved helpful.
Apparently, the ZEN34's multi-color led can also be similarly manipulated through parameters.
Now, I have no idea how much of a drain having the led would have on the 2 CR2032 batteries in the ZEN34, but this would be an exception rather than a rule, since the gate shouldn't be open for too long because of the deer's propensity to wander in and eat all the decorative vegetation, lol.
I also use parameter manipulation for other purposes on ZEN73's and have also done it on GE/Jasco's. I believe others have as well.
What do you think? Practical or Not? If so, would you consider making the driver changes?
