f it works from web interface it should work from orbiter too.
Try to regen orbiter(s) screen, and quick reload the router.
Also you can try to place those devices on your house plan, regen orbiter,
click on "lightning" from orbiter's screen, select the lamp you want to control
and you should be able to turn them on and off and also dim the lamp.
If it still doesn't work, please activate remote assistance and PM me with installation number and remote access password.
