Hi,
I've a new ReefAngel Star controller and an having a bit of difficulty with getting it to control my universal relay. I'm supplying power to the relay (and it shows power), and have the controller set with a few ports to "always on", but none of the ports on the relay are supplying power (even though the code deployed via the web wizard shows the ports as on). My laptop does pick up the relay as a USB device (but unknown device without appropriate driver), even though the miniUSB connection on the relay seems a little loose, so the USB-miniUSB cable seems fine.
Is there a particular position for the three dip switches on the relay (or a doc that describes how they should be set) or only one of the two USB ports on the controller that must be specifically used?
I did notice that I needed ferrite cores around the controller and the relay USB cables to prevent getting locked in a bus error each day (but I'm running both cables alongside each other through a small hole so that's not a big surprise).
Thanks for any advice.

The relay box is supposed to be connected to the RA* and not to your computer.
Leave the dip switches all on the up position. That is ID #1 and I'm assuming your code uses Box1_PortX, right?

Yes, indeed the RA* is connected to the relay via a USB-miniUSB cable (and there's a separate microUSB from the controller to its own power supply). I only connected the relay cable to a laptop temporarily to ensure the cable and relay miniUSB connector were not faulty. The web wizard produces code including this snippet:
// Ports that are always on
ReefAngel.Relay.On( Box1_Port5 );
ReefAngel.Relay.On( Box1_Port6 );
ReefAngel.Relay.On( Box1_Port7 );
ReefAngel.Relay.On( Box1_Port8 );
The GUI "Exp. Relay Box 1" shows those four ports in green. The relay is being supplied 240V and the power light on the relay shows power is on, but there's no power being supplied by any of the eight relay ports even when I put all three dipswitches in "on" (or instead all not in "on") - by "up" do you mean on or off?
The only thing I may have done differently was use a 2 meter USB-miniUSB cable (but I've tried another too) and connected ferrite cores to stop a frequent bus error.

You will need a serial monitor such as putty, tera term or Arduino IDE.
Open the serial monitor at 57600 baud.
Send the log.

Done, but I just get the message:
Code: Select all
2
I2C Mux not found

I also get the same log when I also have the salinity expansion connected, even though I know that does work (as I see its readings in the controller GUI whenever its connected).

Sorry for the delayed response, work does get in the way sometimes...

I believe things are getting sorted, the three dip switches are all set to "on", I've replaced the miniUSB cable again (as it seems it was faulty and later totally failed), and put the ferrite cores back on. Now my relay has power and I can toggle the power on/off using the controller GUI, so the controller now does communicate with the relay.

With the relay and the salinity expansion connected the code now gives the following output:
