I installed a Maestro MS-OpS5M in the bathroom bc my toddler can’t reach the light switch. It controls both the light and fan. I used the 3 way wiring configuration as that’s how the original switch was wired. I initially had to switch the travelers as was directed in the manual. Worked fine. The next day, my husband installed a single pole switch in the garage. The 2 locations are on the same breaker. Now, the bathroom switch won’t work, and 2 other outlets in the living room that are on the same breaker aren’t working. The garage switch still works fine. We bought a new 3 way switch thinking maybe there was a malfunction, but no such luck. I uninstalled the garage switch, but still no success getting the bathroom or other outlets to work. Any ideas on how to fix this, other than needing to bring in an electrician?
