Review on ECOELER 3-Way Motion Sensor Light Switch, Neutral Wire Required | UL Listed & FCC Approved Indoor Activated Switch | 1 Pack by Tiarik Gonzalez

If you understand how to wire a 3way switch, you should be able to wire this.A note of caution: when using it with a second switch, the second switch is not a 3way switch but a regular 2 poles switch.Instructions claim to wire only the two travelers and leave the common unconnected. It cannot work as the travelers will never be connected with each other as it's either traveler connected to the common. so the black and blue wires go to a regular switch or to the common and one of the travellers. It makes more sense to use a 3 way switch and not wire one of its travelers so the switch does not have a ON- OFF writing on it.After I understood that installation was fine. Just make sure your box is large enough as the device is fairly deep and there will be 5 connections to fit in the box too.Bonus point for including the decora white cover (could have included multiple colors to be even better)
