Has anyone been able to make a TP Link dimmer switch work on a 4way system? Here is my current set up on the main switch. Line and Load are wired into the same box.

Your post says 4-way, but the diagram is 3-way.
The TP-Link Kasa series is capable of 3-way installation. $-way installation is not supported by the Kasa.
Thanks! The second satellite switch is fed from the first satellite with the same configuration. Since a smart switch would not go there I didn’t draw it in the diagram. Good to know about Kasa not supporting this set up.
Inovelli reds can do 4 way. The satellites just need power and neutral. However, if you plan on wiring up a new switch at a new location, wire it for a physical dumb switch first because if for any reason you take out the smart switches, your house should be wired for old school as well.
