In this video I'm atoning for a past home automation sin... removing existing functionality from a three-way switch. I'll restore the three-way switching using two smart devices and Tasmota. This process can also be used to create new three-way switching where it didn't exist before, without running any new wiring using Tasmota Device Groups. And it can be extended to include control of multiple lights or devices.
