I utilize it as a core part of my self-hosted infrastructure, as an alternative to IFTTT or Zapier.
I do simple things with it, like monitor GitHub for releases of software I utilize, filter out release candidates and post the details to a Mattermost server. This assists me stay existing With tasks where I preserve a public Docker image for them.
Huginn also does more complicated things like act as the engine for an app running as a series of functions in OpenFaaS. That app pulls information from various sources, aggregates it, dedupes it according to numerous requirements, does a lot of subsequent lookups, stores results in Mongo and after that gathers the output once a day and sends it as an e-mail.
Huginn is an excellent tool.
