Today I updated to firmware v1.1.2 mostly because I wanted MQTT username/password. The update was successful.
I noted after reboot that under Options/Advanced that the Host Name: field was not retained and was replaced with OG_XXXXXX where formerly I had it as simply og. I reset this to og and rebooted and it appears to take affect.
I noticed however that when the device connects to my MQTT server, it is still using the OG_XXXXXX as clientID rather than the Host Name I specified whereas before this update, the clientID was my previously specified Host Name. Bug?
