With this datapack, you can easily set up wireless redstone transmission/reception.
Redstone lamps are linked to a channel by placing one or more ender eyes on their face (in an item frame), before using the /trigger command on "WRLink" to activate the eye.
Lamps on the same channel will activate one another. When one turns on, the others become redstone blocks until the first turns off again.
You can also check what channel an eye is on, or which eyes are on a given channel, by triggering "WRGetChannel" or "WRTestChannel", respectively.
The /trigger command is automatically enabled by the pack for all players for these objectives.
To install the datapack, just place the downloaded .zip file into your world save's "datapacks" directory. Do not unzip the file beforehand.
