Hey @OldSurferDude
I think we have a missunderstanding here. I have my gateways running on ESP32. When I add the integration I can enter the IP in this dialog:
If you want to change the IP number of the gateway (or the MQTT topic or the serial port), there is no way to do this:

I had a similar situation. First you have to delete all the MySensors devices in HA. This is aggravated by HA wanting the devices to be on line before you delete them. You may have to delete the MySensors data in the HA config directory. You may even have to uninstall MySensors from HA. Then shutdown HA. Next, turn off your gateway. Are you using MQTT for messaging? You'll have delete the MySensors data from there, too. (MQTT Explorer is good for doing this)
Then start HA. Did your MySensors devices come back as zombies? That's the problem. Try deleting them again. Are they data still in MQTT?
OK, now start again.
I had documented how to do all this deleting in HA Forum, HA/Discord and here, but I can't find that documentation now. grrrr

What I did not try but might work: copy your persistence file, delete the old GW and create a new one with the persistence file you copied. Maybe the devices are preserved like this. Maybe you should create a full backup before...
