I’ve bought a TKB double dimmer switch (TZ55D) that doesn’t seem to want to play ball with Smartthings (its left paddle works as expected to activate the load, but the right paddle, which I supposedly can use to control something else via association group 2, is not accessible), and so am looking at writing my own DTH for it, and was planning on using your tool to help.
I tested the tweaker with some other devices (Fibaro dimmer etc) and it worked as expected. Thanks for your hard work.
When I tried it on the double dimmer, I get the following from the log for any of the “scan” buttons, and nothing at all for any of the “print” buttons:
java.lang.NullPointerException: Cannot invoke method startsWith() on null object @ line 1618
The synced tile has a green tick.
I assume it’s a problem with the device’s interaction with Smartthings, but wonder if there’s anything you can advise I do to fix this?
Thanks in advance.
