[mihome] Gateway goes offline after 5 minutes

bug

I have a Xiaomi gateway v2. I have been using it for my OH 2.5 instance without …any issues. I installed a OH 3.2 instance and started configuring it. I added the Xiaomi binding and adding a V2 gateway in. The Thing seems to be connected ok at first, showing all the connected devices etc, however after 5 minutes or so, it would go to disconnect state. Since I have both OH 2.5 and OH 3.2 instances, I can confirm that the gateway is working as expected with the OH 2.5. A quick search in the community forum shows that others have the same issue, and it can be fixed by adding serialNumber (MAC address of gateway without : or -) in the Thing configuration. ## Expected Behavior It seems like serialNumber is a required field, it should be added as a required field in the add Thing menu. ## Current Behavior When adding gateway, it does not ask for serialNumber. Without it the Thing would go offline after 5 minutes. ## Possible Solution Make serialNumber a required field ## Steps to Reproduce (for Bugs) 1. Add Xiaomi binding in OH 3.2 2. Add Thing -> Xiaomi -> Xiaomi Mi Smart Home Bridge 3. Enter in IP and developer key ## Context Thing don't work properly without entering the serial number ## Your Environment OH 3.2 on docker in Raspberry Pi 4/Zerio

to fix you have to go to Code section of your bridge and manually add serial number:

UID: mihome:bridge:XXXXXXXXXXX
label: Xiaomi Mi Smart Home Bridge
thingTypeUID: mihome:bridge
configuration:
  ipAddress: 192.168.X.XXX
  serialNumber: XXXXXXXXXXX
  port: 9898
  key: XXXXXXXXXXXXXXXX

serianNumber is the line you have to add
