I was trying to use entangled blocks to do wireless redstone control, but to my surprise this did not work.

I think this feature would be very nice to have in future versions of the mod.

Expected result:

Actual result:

By that logic should an entangled block that can be controlled with a redstone signal, e.g. on/off, not respond to a lever on the entangled block itself? Because that also does not seem to work... E.g I entangle a any machine that can be turned off with a redstone signal and then I put a lever on the entangled block, however, this does not seem to do anything.

Am I understanding your response incorrectly?

No, the problem is that in order to give a block a redstone signal, it needs to have a block outputting that redstone signal on one of its six sides. The entangled block has no controll over what's around the bound block, hence that is not possible.

What is possible, is that if you bind the entangled block to a block which emits a redstone signal, like a lever or a redstone block, then the entangled block can emit the same signal to blocks around itself.

This is not possible with the way Minecraft works, only a block itself can emit a redstone signal.
It does work the other way around though. If you bind the entangled block to something which emits a redstone signal or which gives a comparator output, the entangled block will match it
