Electronic Speed Controller for Brushless DC Motor Ceiling Fan

I am looking to install a ceiling fan that uses a BLDC or brushless DC motor. The motor has 3 leads - I assume it is a sensorless version. It is 24v DC and comes with a power converter/remote control receiver to change speed and direction (ie clockwise, counterclockwise rotation).

I want to eliminate the remote control the fan came with and replace it with a electronic speed controller (ESC) and Shelly device so that I can control the fan on/off, speed, and rotation direction from within Home Assistant. I will use a standalone power converter to supply the ESC and DC Motor with 24VDC.

It appears the ESC would use PWM to set the speed of the fan. Could I use something like a 0-10v dimmer from Shelly as the input for the ESC? Some of the ESC devices I see online come with what looks like a potentiometer. I wonder if I couldn't just remove that and replace it with a Shelly of some sort.

I'm considering an ESC, something like what's below. I would want to replace the potentiometer (on/off and speed) and toggle switch (reverse-CW/CCW) with Shelly devices so that they could be changed remotely. It seems I would need 3 separate Shelly relays to control on/off, speed, and reverse.

So I figured out a solution. First, I learned that the potentiometer can be replaced with a 0-5v PLC. This was key.

I wired 24VDC in to the ESC board and also to a Shelly 1/Gen 3 device. I connected 120VAC to a Shelly 0-10v dimmer.

The control inputs on the ESC are labeled 5V, Sign, Z/F, VN, and GND. Referencing the diagram above and other postings I found online, I then connected the O terminal on the Shelly 1 to Z/F and the I terminal on the Shelly to GND. This dry contact controls the rotation of the BLDC motor - either clockwise or counterclockwise depending on whether the dry contact is open or closed.

Then I connected the + terminal on the Shelly 0-10v dimmer to VN and the - terminal on the Shelly to GND. In the Shelly software, I set the max "brightness" for the dimmer to 50 and restarted the Shelly, as is required after this setting change. The dimmer within the app now controls on/off for the fan motor as well as the speed.

Now I can use other devices, remotes, wall switches, and scenes to control my fan, which previously arrived with a single remote and no other means to control the fan. It was a huge PIA to figure this out, but I am glad I did and hopefully someone else finds this helpful.
