How to control from a smartphone using the 0-10V protocol?

Question

Electronics

It is necessary to apply a voltage of 0-10V to the input of the smart load by controlling the slider from the phone screen.
So far there is this:
1. For the project, I found a touch panel with a remote control that outputs 0-10V . Good degree of readiness, but bad that is not from a smartphone.
2. People are designing 0-10V with Arduino control . And arudin can be paired with a phone via bluetooth, and in the playmarket there are applications with an interface for controlling arudin , incl. with sliders. It’s good that it’s from a smartphone, but it’s bad that development is needed.
Is there any simple out-of-the-box solution?
upd: I think I found it - Amelech bluetooth led controller , now it would be easier to understand how it or analogues are easier to buy.
