I’m familiar with ebike electronics and have been using Regen successfully with the Phaserunner Controller and Direct Drive hub motors.
I’ve been looking for affordable alternatives and found this 250w controller from PSWPower which claims it has Regen. It has a brake input with positive negative and signal. The provided throttle works with the throttle input and spins the motor, but when I connect the throttle to the brake input, it functions, but the signal voltages don’t seem right. The positive reads 4.8v with no throttle connected and 5v between ground and signal. When I connect the throttle, the signal voltage drops to 2.2v and increases to 4.6v when twisting the throttle. This results in the controller not spinning the motor as it sees a high signal.
As per the instructions, I connect the grey wires to enable regen, but nothing happens when twisting the throttle connected to the brake line. The motor can be spun freely by hand.
This is the controller in question:

I bought three of these and they all behave the same way.
I also tried this controller with a 6.5-inch sensored direct drive scooter motor and it wouldn’t work. So far it works ok with a Xiongda YTW-06, a Bafang G01 (SWXH) and the ‘Edge’ 1500w direct drive motor.
I have some 15A square wave controllers that work with all of the motors mentioned, so it’s a big shame I can’t get it working with the scooter motor. Anyone have an idea of why it might not work with all motors, when a seemingly simpler controller is fine?
I’ve made some videos to show the regen setup not working, also a video showing the noise difference between sinewave vs squarewave controllers on all of these motors. The sinewave is quieter, but is also a bit slower I think.
I’ve noticed that the Sinewave controller has some functions that only work with a display connected, which is strange. For example, there is a -30% speed reduction jumper. With the display disconnected, it defaults to -30% regardless of the white cables being connected or not. I wondered if the regen might be the same, but it doesn’t work regardless of the display being connected or not, or with the grey wires being connected or not.

And here are the connections:
The one thing interesting about this in relation to the regen is that it suggests you can use regular 2-pin brake lever switch’s by shorting the signal to ground. I confirmed this works but only as a motor cutoff. There was no regen braking with either combination of display connected or not, or grey wires shorted or not.
I’m posting this here as the support I’ve been getting from PSWPower is not so good so far. Hope someone may be able to offer some suggestions on what to do!
I think I can return these, but I will be down by two lots of courier and the import duty I paid to get it here.
Thanks in advance Team ES
