Wiring assistance needed hs210
Hello, I wired up my new hs210 three way switch. Following the app instructions I only installed 1 as the other switch location did not have a neutral bundle, rather just three cables directly attached to the switch (white, red, black).
For the other switch, I replaced all three cables (two travelers and the line/load) then connected the neutral from switch to bundle. It appeared to work... The dumb switch turned the lights on and off, and I was able to connect the hs210 to my Kassa app successfully. But toggling the hs210 switch manually or through the app had no affect on the lights.
I am attaching photos of the previous switch that was replaced and it's wires.
