MySensors Newbie Questions

[CrankyCoder]

I normally don't post multiple questions in 1 post. But most of these are of the type "can mysensors ______" so yes and now will lead me to creating other posts :)

So here we go!!

1. can mysensors acknowledge receipt of a command?
2. is it possible to have multiple gateway devices setup for fault tolerance?
3. can mysensors "sensor/buttons" speak directly to another node without going through the gateway?

Thanks!!!
Very excited to have come across mysensors!

Welcome @Jason-Brunk

1. Yes
2. No
3. Depends on you topology. A sensor always sends to its parent node. If a route to the other node exists in the parent it will direct it without deliver the message further back in the hierarchy.

Gateway -> Repeater -> Node A
                 \-> Node B

A sending to B will will only pass Repeater.

Second argument to send() enables end-to-end ack.
