Question from Ken in Puerto Rico
I purchased a smart switch, KS-602F to replace a three way switch. Do I also have to replace the other 3 way switch that this circuit is tied to with another smart switch?
If you have two pcs of KS-602F Tuya 3 way switch, you could replace both two.
If you only have one pc of the KS-602F, it's also ok to change your old 3-way switch by replacing one switch. Please kindly note that only the light switch connected to the load wire or lights should be replaced KS-602F. The load wire is not through electricity. The other 3-way wireless light switch doesn't need to be replaced. If replacing the wrong switch, it will not work well.
3-way smart switch wiring as below,
KS-602F belongs to the KS-602 series, it has KS-602, KS-602S, KS-602H/K for wholesale option. Please see Kesen light switch to see more.
