hi @carozoynarizota the mod is branch has a static dictionary for a modbus device. if you need a specific modbus dictionary share the specs of your device let me know |

Hi Roberto! I tried late at night last changes. They work perfect, de 5kmh default speed and the top setting for the frequency not to put the VFD under error message. I also found how to change the step from 0.5 to 0.1, and even the predefined speeds...thats awsome. Still didn´t get where to change from speed to pace. I thinks its almost done. What´s next? What about the fixed com4 on window? What does it take to pick the right port in Linux? |

Amazing!
Super!
You have to enable the pace tile in the settings. Did you?
I can add a new setting for the comport. The Linux port should be already work, just need to change the com4 label :) |

Hi Roberto.
Yes it is enabled, but the +/- are just on the speed tile. I don't know if it supports to place changes directly from the pace tile. I also having a lot of problems with the tiles. Tried to arrange them but I only move one and then it goes back to its position in line, I am also not being able to si if I can change its size. There's also a font problem being bigger than the tile.
The links you gave me have only the APK for android and the windows versions, not the linux one. I don't know how to install this demo version for linux. I installed again the actual release following the steps in the installation manual, under Ubuntu for windows. It runs OK, but as it doesn't find any TM I am not able to see if the tiles arrangement works there. I set the Fake Treadmill feature on, restart QZ but nothing changes (no dashboard). Moving to something different. On the final release I see you publish the android and ios version on each store. But it seems to be also a link for a windows version on google, but its seems to be unavailable:

you have to change the speed from the speed tile, but since pace and speed are linked you will see pace changes too
for the font issue you have to change the dpi for qz. you can do in the advanced settings of the executable on windows. for the order of the tiles you have to change the order index in the tiles settings.
i'm not building the linux version on the CI here on github. i can do it if you need.
no don't follow this, qz runs natively on linux.
i'm not updating the windows version on the microsoft store because of the microsoft policies. the windows version is only here on github |

Roberto I tried to run the linux file picked from the following link. That was on ubuntu desktop under VirtualBOX, change it properties as an executable and run it but nothing happens. Am I doing it right? https://github.com/cagnulein/qdomyos-zwift/actions/runs/8768731219 On the nighlty build there is no linux version built. Are all this features implemented there? I will be ordering two OTG adapters from aliexpress (for android and ipad). Ipad would be my first option, but I would also like to have the linux option. |

… Hi Roberto, my AC motor controller is a VFD-M model. Documentation can be
found by Delta or Danfoss as its brand, model 176F7300.
On the attached pdf, appendix D there is detailed information about modbus
communication.
Danfoss VLT Micro - 176F7330.pdf
<https://github.com/cagnulein/qdomyos-zwift/files/14782286/Danfoss.VLT.Micro.-.176F7330.pdf>
For modbus communications I been doing tests with this settings:
00: MODBUS ASCII mode, <7,N,2>
03: MODBUS RTU mode, <8,N,2>
With manufacturer specific software I was able to read all the registers
(and get the query also). Some of them are to control specific parameters,
like setting the AC motor frequency, and at specific addresses toggling
certain bits I remember you can for example start, stop or reverse the
motor.
With all this information I was able to run with an arduino a code that
start the treadmill and make it increase speed every certain time. Of
course code is not mine but copied from the internet, just with a few
modifications to match the documentation. For example no one uses on their
VFDs those parity settings, most of them has modes that are supported on
software serial library and for mine it has to be hardware serial.
Well thats all I can say now, I don't know if its usefull or if it
justifies the effort to get you involved.
As final examples I put here the output I get through reading all the
registers in ASCII or RTU. I also have examples setting frequency, or
running/stopping the treadmil.

… Roberto I've being doing some tests to get the right commands. I think we
only need Start, Stop and Send Frequency.
Frequency is from 0 to 60, with two decimals but is sent in HEXA. So ie to
set 24,44Hz, then you have to send 2444 as an integer. In HEXA 0988 will be
our value.
Then to set a new frequency 01 for device ID,06 write operation, 2001 the
expected address, an 0988 our value without CRC should be :010620010988
In the attached file you have the Start, Stop, and Freq commands from 0 to
20Hz. Both ASCII and RTU.
If it happens to be usefull to read frequency, then command is
:010321020001
If a communication error occurs, you won't receive an answer or maybe an
error response. The display will show you an error like "C-##", that error
is cleared by the reset command also in the table.
Let me know if you need further details or tests.

Hi, I installed the app on a Raspberry pi 3b+ just to see how it goes. All of what a read within the guides or youtube makes me think that the app act just as a bridge between zwift and bluetooth enabled devices. These can be FTMS treadmils or BLE sensors.
What I am trying to figure out if it will help me control my AC motor through the VFD using modbus. Despite being a modbus branch, I see no option to set for example how the Pi should connect to an external device through an RS485 adapter.
My setup is just this basic treadmill controlled by buttons that goes directly to the VFD. To know my pace I put a hall sensor and with an ESP32 over BT I have that on zwift. Setting different speeds or intervale training is a nightmare with the buttons, as every push is a 0.1Hz step in the AC motor.
