Quick Q - I upgraded from 2.5.11 to 2.5.12 a couple of days ago and it got complicated due to the bintray shutdown and had to download the openHAB2-addons.kar and set remote = false in my addons.cfg.
Everything except MQTT1 works once I did this.
However I’m still using MQTT1 exclusively and I have some reasonably complex transforms of MQTT data in my Items files which I think will be messy to replicate. So moving off V1 will be a fair bit of work.
I’ve ended up reverting to my backup (2.5.11) because I couldn’t see how to get MQTT1.x working and needed a working system
My 2 Qs
Is it possible to get MQTTV1 functioning on 2.5.12?
Do I have to upgrade to MQTT2 before moving to OH3?
