I have a black wire, red wire, white wire, and copper wire, but there's no second black wire. The previous switch was on a three way circuit, but I'm thinking now that one of the switches wasn't a 3 way switch because power would only be there if all of the switches were on. So, we only use one switch, the switch I'm replacing with a HS 210. I deleted the other two switches. It was working fine with the old switch. I get power with the new switch, and I can connect to it through the phone. The lights just won't turn on and off. Any ideas?
