It would extremely useful to have teleporters linking homes in multiplayer. bc not everyone is always on or at the right place, /tp isn't as useful as it could be - and by building teleporters, it feels...less cheaty, since you have to grind for the resources.
There's this one that was created recently (Aug 2019), but it seems like it's up to 1.12. Not sure if it could still work for 1.14: https://www.curseforge.com/minecraft/mc-mods/vanilla-teleporters/files
Or, alternatively, there is this mod - which is up to date, but not as complex as the previous mod: http://www.9minecraft.net/simple-teleporters-mod/
