I couldn’t find any info on a shortage or anything but it’s been out of stock at every local store I’ve been to for the past month at least. I finally found some a few days ago at Costco (who were out last time I went) so hopefully the availability is getting better
You need to edit your configuration.yaml file to exclude certain sensors or values. I excluded some of the more chatty sensors that I didn’t need and my disk use went from around 40gb to 150mb
