Just follow the steps you mentioned, no luck....
1. Long press e-control TC2-2 and then select Share Configuration
2. Switch to IHC and then add device
3. Select smart switch & pick TC2-2, fill in device name & switch 1&2 name, then new switch created
4. DURING pairing process,I long press physical TC2-2 button until my light flickering, at IHC press Green button configuration.
5. Light auto stop flickering and IHC asked me did light stop flickering.... This is the time I think no matter what I tried all unsuccessful to pair....
6. If I press Yes, switch button in IHC not working.... IF I press No, repeat step 4 & 5 infinite tries...
Any ideas for me to get this over?
That's struggle me quite long already
