Very well packed. Not tested yet
Now that I've tested it for a few days, I can say that it works flawlessly. Relays get a bit hot when in operation, but nothing to worry about. The only drawback I've found is that the manufacturer only implemented Modbus Function Codes 03 and 06, but not 16. This means that you can only open/close one relay per instruction (they also implemented a command to open/close all of them at once), but not a custom selection of them.
