Smartrise used to have a great tech-support, but its not good anymore. Ive heard many of their key tech support people have left the company and that's why it sucks now. I am glad people in this forum can still help.
Be careful about their brake control system specially their brake boards, they are not safe at all. My mechanic was on top of the car on construction mode and the brake board failed in an unsafe state and kept the brake open all the time, even the brake contactor didn't drop! He was lucky and could jump off the car.
All their tech support did was to send a new brake board but I don't feel safe to use it again. I don't know how they get safety certifications!
