Sorry.. when they were connected they had voltage (both of them). When disconnected both were not hot

Yes.. i removed the wire from the siwthc to test it... capped it and everything. Made 100% sure that it was the right one and no interference was disturbing the reading.

Voltage is on both travellers for the HS210... My last conclusion is that the light is hooked up wrong... I'm defeated ahah... I'll be calling an electrician once lockdown ends in Ontario.

What was the solution to this?? Im using the 3way switches but the switches aren't getting turned on...my neutrals have power but there is still some light leakage.

I've reset both switches, I'm confident the wiring is hooked up right. My neutrals are getting power. How do I know if the switch is defective??
