Connected one HS210 to a 4 way circuit... one to a 3 way... both with one Dimmer on the other end. Both have the same issue:
Everything works fine with the dimmer set to medium or high. If I set the dimmer to low (my preferred setting), the HS210 looses connectivity (and light goes out).
Making sure the HS210 is the first light in the circuit is not possible for the 4 way, in that there is no neutral wire in that box, nor in box 2. Box 1 has the dimmer, box 2 the 4 way switch, box 3 the HS210 (the only box with neutral). Any recommendations?
Change to symptoms: when dimmer is set to low (on either circuit) the 3 way or 4 way function fails manually.
