FYI - I have updated this to use the new Slack Python SDK and dockerised it - see https://hub.docker.com/repository/docker/sumnerboy12/slackhab.
Thank you, Ben. I’ve been running your dockerised version since you shared it and it’s as great as it ever was. It stops occasionally for some odd reason but restarts no problem. I also switched to the dockerised mqttwarn and aside from needing to add the slack library to the image, also working great. Cheers! John
Good to hear! I have also switched to dockerised mqttwarn. Thanks for the feedback.
