I've been using Philips brand dimmable led bulbs for many years and never had any flickering at low light intensity . ( with 2477d dimmers switches) .

5.0.16C rc1 overboard limits ! 12 minutes and 999 seconds ? Somewhere this could, in my opinion, cause a glitch. bug or no bug reported?

@MrBill Manual explaining jumper and other functions involved.Advanced External Sensor Use, multi scenes https://www.insteon.com.au/manuals/2843-222.pdf More recent modules may be different

Module 2843-222 I would suggest this because it seems to work for me Make sure the device in not paired. remove battery, place magnet close module ( in the correct position) remove jumper ... don't forget the put it back when done replace battery ( only after 10-15 sec) After the battery is in you should get one flash ( led) fast press for one more flash.... then...... press sw until you get led steady flash enter ID # to pair....... you should have the 3 nodes. if not.....and if you have the led still flashing, short press sw...... you should see led double fast flash now delete the device. restart pairing. Only delete the device in the double flash node unpair. If I don't do this on my module I get 2 nodes. Maybe it will work for you.?

@Craigb These modules (none dual-band) may not communicate directly with the PLM if they are set on a different “ phase ” of the electrical system. They would rely on the mesh or cascading network provided by the other modules. You can set the PLM in => Phase Detection Mode to do a test. You might have to move the modules to an other ac receptacle for the test. Otherwise a bad mesh component might be corrupted or electrical interference power bars filtering ...etc.

@Craigb I have two of the ApplianceLinc 2456S3 - v.42 working with 5.0.16C .Don't see any communication errors and they respond to the commands, can read the link table etc.. No errors after a restart Those modules are not dual band. I would suggest a module factory reset and move them to a different location for a test ( closer to the plm) and try again. If they work after this, than you can redo the scenes etc...
