How many risers do you have? Ensure that the riser board is properly connected to the master. Verify the setting of the hall network termination dipswitch. Make sure that only the last hall board's CAN-BUS termination dipswitch is turned on, and the rest are turned off. Use a meter to measure the resistance of the hall network. You should expect a reading of around 60 ohms.

I hope this isn't a software-related issue, my friend. Regrettably, Smartrise has outsourced all of their software development, bug tracking, and fixing to a company in Lebanon. Apparently, they don't have any software engineers here in the US to promptly address these problems.

Best of luck.
