I was really pleased to see this and expected the UK model to be the same (at least the 240V I'm interested in) so why does Festool UK list the "Max. appliance socket connected load" as 1610 W, when Festool DE shows 2200 W  [sad]

This comes up all the time and I'm sure that Festool UK say you can use any Festool tool with any Festool vac (that's what I was always told anyway), the max load is a guide for if you use other makes of tool with your Festool vac.

This isn't UK but kind of explains it.

Why not contact Festool UK to get a definitive answer for us, I would be interested to know what their current view is  [smile]

Hey Festita…just curious what a W top is.

.. Soft-top, Hard-top, Sun-top, Bimini-top, T-top ..I figured Wood-top..  [big grin]
(Maybe it’s because I’m all into boats these days.. refurbishing, rigging outboard and so on  [smile] - I’ll make a new seat with waterproof plywood as a base before transferring the teak from the old battered base, that’ll be fun. Nothing I’ve done before anyway, at least some woodworking  [smile])
“The Stig” Yes, it is true, at least some part of it..

Re: Common Festool/Makita/etc Bluetooth protocols

…it would be great to see powertool manufacturers adopt a common Bluetooth protocol for tools to switch dust extraction on/off — even just the German manufacturers…

Yes, definitely.  The good news is that the Festool kit (BT Battery/Remote/CT Receiver) have DFU support for updating firmware.  The Makita Bluetooth modules (WUT01) appear to have this too—so there is some hope for patching to support a common standard.

…Such a Bluetooth BLE protocol could be extremely simple: a hypothetical "VAC: Vacuums are Connected" protocol could be done by BLE advertisements (beaconing), a single registered 16-bit UUID and a single byte for tool run-status; (total = +5 bytes) which should fit in with the BLE packet size, along with the existing manufacturer data.  Light traffic lights, needs four states: PRERUN/RUN/PRESTOP/STOP corresponding to actions: 1. LED on, 2. Motor on, 3. Motor off (but clear hose), 4. Remote MAN = immediate off.

However, the mean-time, a workable solution is a mobile phone (with Bluetooth), or a Linux-based Raspberry Pi Zero W (with Bluetooth), acting as a hub and translating the vendor specific on/off protocols.  So far have Makita AWS documented, and Festool/Tooltech partially reverse-engineered ... waiting on access to more hardware.  Can also receive/decode the DeWalt WTC 433.92 MHz on/off signal, but only have one tool obtained as an example.

(PS. If there is anyone near Frankfurt/Heidelberg, with multiple pieces of Bluetooth-capable powertools [including Festool], please let me know!).

It hasn't stolen my heart, that's for sure. Suddenly it has this little computer on-board, that all the time, for no reason says: "Suck it up yourself". My old Mini just worked, all the time.

Ha, yeah.

But at least it 'filter clean handle' actually does something. If you suck up drywall / concrete dust, the 26 will just loose suction gradually while the new Midi allows it to be restored for 90%+.

However, when sucking up larger debris, it does not fill the bag. It launches everything forward, up to clogging the hose while there is a ton of free space directly below where the filter sits on top of the bag.

So if the firmware is updatable. And it seems someone else reverse engineered the serial protocol, why not just write some custom firmware from scratch. Festool uses Nordic chips, so it shouldn’t be too difficult. From what I’ve seen from the remotes, they send advertisements whether paired or not. I bet the batteries work similar. So you could do what I did to make the relay adapter and just capture the advertisements.

As you’ve said elsewhere reversing the festool protocol is a little more difficult because it is encrypted. It’s too bad I just saw this, as I just got back from Frankfurt. Although I think I’ll be back in a couple of weeks (2nd week of Feb). I would have loved to meet up and swap knowledge
