Also the wahoo device are coming from qz, they allow you to use Wi-Fi instead of bluetooth!
I’m going to bed now, Italy here

Will check out the qz control tomorrow (UK here!). And then log on GitHub if it doesn’t work!
Matt,
Try connecting using the Wahoo Tread that appears. It’s much more stable. Might need to change a setting in experimental options to get it working but i think the fact you can see means it’s probably as it should be.
OK, will give that a go. But I think I may need to go through some more treadmill specific settings first of all as I tried the Horizon specific app (atZone) and that failed to connect properly too this morning when I tried it.
I tried QZ standalone too and that couldn’t / didn’t control the treadmill inclination by clicking the plus / minus buttons. So it felt like QZ was receiving info fine, but the treadmill wasn’t responding to commands received either via QZ or via the atZone app. Which makes me wonder if there is a treadmill firmware thing I need to resolve first of all. So I’ll head off down that rabbit hole first of all.
Looks like I need to install a bluetooth update Firmware Q20_V10.21.13 at the very least having tracked down a support page. That’s tonights fun and games then!
Ok, remember that some Horizon firmware have the inclination/speed control by bluetooth blocked, so that’s why I asked in the first place to test the inclination tile.
Let me know!
Fingers crossed that the device accepts it ultimately! Found the guide on the FB group for precisely my device that Jana Bouc had produced so I’ve got a reasonable level of confidence that it will all work in the end, even though that guide is Peloton specific.
Firmware and Bluetooth updates to the Horizon 7.0AT-02 was the final piece in the jigsaw. All working perfectly now within zwift. Just need to work out how to stop the treadmill auto starting at a low speed as soon as zwift is connected now. Thanks for the help so far!

Slightly odd behaviour that but at least you know it does it so can plan around it.
I.e. Don’t connect it whilst stood on it.

So now I’ve got the tech working (and I am a complete noob when it comes to treadmill running) the next few things I need to explore are:-
- can I create a meetup which is really short so that when it ends I can “free run” around the zwift world, choosing different road junctions etc and still have the autoincline working. Looks like the shortest meetup in time is 30mins on zwift, so perhaps would have to programme this as a short distance and then maybe see what happens
- can the QZ app control the speed of the treadmill so that I can programme a specific intervals workout and pace and have it change the treadmill pace as required (obviously taking care not to set things too fast!); and how this would work wrt using a meetup / using the “first choose bike, then switch to run meetup” approach.
- if QZ can control speed as well as inclination, is there a way to dynamically change pace so that when running uphill the pace of the treadmill slows by an appropriate amount to keep effort similar, as you would when running outdoors? Or am I overthinking things, and in really just knocking down the pace a little manually is the right approach.
Plenty to play and experiment with.
Hi Matt, are you on PC with zwift? As I said above with PC you can have auto inclination and auto speed with workout or free run without the meetup if you want!
I’m working also on the same thing on android!
About your point, you can load the ZWO file from Zwift to have auto incline and auto speed right now, so you can follow the zwift workout automatically!
QZ can control speed, but by default is disabled, you need to enable in the treadmill settings, enable force speed.
Also QZ has a PID Heart rate function that simulates what you’re saying. So for example set the PID function to 3 (zone 3), while zwift increase the inclination (so qz does on your treadmill), your HR will go high and so QZ will keep the speed aligned to your HR zone (slowing the speed)! Give it a try! It’s how I usually use zwift and my treadmill
Not yet on PC, but hope to be soon. Need to convince my work that I can get admin rights to install Zwift!!
So for the moment I am on Android on two phones.
What does “load the zwo” file mean in practice? Do I need to get Zwift to save / output a file which I then load into QZ? Sorry for all of the questions, I’m sure there are documents already setting out how to do this!!
I like the PID idea (I use one on my espresso machine to control the boiler temperature!) so will look into that too!
On zwift (I don’t know where it stores on android) you can save the workout file as ZWO file.
Put them in the qz directory, under training programs subfolder.
Then on QZ you can load them on the left side bar, open train program, select it, press start together with zwift and you will have auto speed and auto inclination on zwift!

How does the Wahoo Tread option differ from selecting my phone? (To be fair, the phone worked fine!) Does it bring any additional benefits?
the mains are:
- you can run zwift and qz on the same android device (you need to enable the android notification first in the experimental settings and restart qz)
- wifi is more stable than bluetooth
But how does “wifi” work if my treadmill is bluetooth only? And if I’m running zwift and qz on the same phone, where does “wifi” come into play? Sorry for the persistent questions!!!
Yes, it will work even if your treadmill is bluetooth. The wifi comes into play from qz to zwift, not from qz to the treadmill
The “wifi” concept comes into play even if you are using both on the same device because you’re using a TCP/IP socket. So the wifi things, is more a network thing rather than wireless signal

Tried out the Wahoo Tread option last night running on the same Android phone as Zwift. First time it worked for about 30s and then the avatar stopped running for no obvious reason. Second attempt it did work for a longer period but as I was only demo-ing it for myself didn’t leave it running longer than about 10 minutes in total. Will give it a proper go “in anger” tonight maybe with an hour’s run.
Set the Zwift event to be on the track for 0.2 miles only which meant that I could free-run after that which was what I was mainly experimenting with which I think is a good option to avoid just having to run the set routes.
I’ve got a hilly marathon to run later in the year, so maybe I’ll try Road to Sky some day 
wahoo tread on the same device? be sure that your phone is capable to run 2 big apps on the same time
Pixel 7a. Seemed to cope ok but maybe I got the wrong impression, I thought you’d suggested that using on the same device was the purpose of the WiFi wahoo tread option?
Happily I should have a Windows device to use mostly from now on though!
