@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.

I have encountered the same situation trying to use a switch to control some blinds.
Has there been any update on this issue from either Home Assistant or MySensors, or any workaround developed?
Hi, friend!
He also became interested in the Home Assistant system, but was upset by the lack of support OTA.
I use a system Majordomo for MySensors devices and my Ethernet-RS485 gateways are based on ENC28J60.
And I found such an idea for myself - to implement a proxy for the TCP protocol in order to implement a parallel connection to the gateway of two systems at the same time.
I tested this solution and it turned out to work - I was able to flash via OTA , while simultaneously receiving data in Home Assistant.
Perhaps this idea will be of interest to you.
