MQTT gateway help!

[Multimax]

Hello, i have an serial node running via usb cable to an rpi with home assistent - it works fine, but trying to transport the data via rs485, or mqtt not working. i found an mqtt node, but wtih serveral relays and buttons - i run out of understanding... it only show one relay in homeassistant :-(. SO dos someone have an multi relay+button code as works under homeassistant - they will share, so i and find my mistake. (i use arduino mega+w5500)

@Multimax do you send initial states for all children for this multi relay node? HA won't show anything that hasn't sent initial data to show.
