Clearly you are running the setup with no ill effects, so can you possibly please explain how to do this? I’ve heard about having to run a wire or something the length of the hose? Or into the wall? Or is it just a matter or buying the right hoses? Any tips would be greatly appreciated. My Midi currently has the hose that comes with it by default.
The static issues with the Festool stacking Oneida is ancient data. The version 1 Oneida was the problem. They’ve been shipping version 2 for almost 2 years now. I have version 2. It does not suffer from what you’ve read about:
A) Festool now lists the version 2 Oneida itself.
B) Oneida has published several independent evaluations that show the problem is fixed.
C) Oneida provides a simple test procedure to prove for yourself that the problem is fixed.
The stacking Oneida, version 2, is made of conductive plastic. Just stack it on the Festool.
Be sure to build the Oneida according the instructions such that the top is connected to the bottom via the provided wires.
One must use conductive tubing with conductive connectors. All Festool official tubing meets this requirement. The Festool tubing tends to be a bit pricey but it is of the highest quality and is designed to resist abrasion. There are alternate sources for quality conductive tubing… if people find they want to use these, let me know and I’ll dig them up.
The Oneida comes with conductive 50mm tubing to run from the Festool to the Oneida. So one would want to use 50 mm conductive tubing to go from the Oneida to the Nomad enclosure. If you’re pinched for budget, use you existing tubing - with an adapter (conductive).
One needs wires only when bridging non conductive tubing connectors. Just use conductive connectors - if you need them as all.
Be sure to check you wall sockets for proper ground and neutral. Is that is wrong, everything else doesn’t matter.

P.S.
A few vacuum tubing rules:
A) Use the largest diameter tubing one can use.
This reduces vacuum resistance due to “friction” with the tubing walls (departure from laminar (non-turbulent flow).
B) Never reduce the tubing diameter and then increase again.
This creates significant turbulence and drastically reduces the effectiveness of the vacuum.
C) It’s OK to have the tubing diameter to constantly increase - from the perspective of pick up to the dust collector.
The smallest diameter segment should be as large as practical (usually on the pick up end).
D) Use the largest diameter tubing - from the perspective of dust collector to pick up - for as long as you can.
Let the air flow as unimpeded as possible for as long as possible.
E) Minimize the number of turns, adapters and tubing segments.
Any turns/bends should use the smallest angle possible.
F) Transitions - from one diameter to another - should have smooth internal surfaces whenever possible.
Avoid abrupt transitions.
H) Keep the total length of tubing - from pick up to dust collector - as short as possible.
Less tubing, less resistance, better air flow.
