    Hello,

    mongodb seems to be buggy

    Pulling egeoffrey-database-mongodb (egeoffrey/egeoffrey-database-mongodb:master-arm32v6)...
    ERROR: manifest for egeoffrey/egeoffrey-database-mongodb:master-arm32v6 not found: manifest unknown: manifest unknown

    Regards

    Hi, mongodb support is still experimental and available for amd64 architecture only at this time. Generally speaking this is intended for a scenario in which someone is willing to host dozens of houses and having everything in memory (like redis does) would not scale. For standard, on-prem installation the egeoffrey-database (based on redis) is and will always be the preferred choice (so to avoid stressing the raspberry SD card with too many reads).
    Thanks

    Just to let you know MongoDB support is now officially available and supported by egeoffrey-controller starting from v1.1. controller/db configuration file is automatically upgraded to allow choosing the database type.

    However, this is still intended for a complex ISP scenario when hosting multiple houses and redis approach to keep everything in memory would come with a high cost. For this reason the package egeoffrey-database-mongodb is available for amd64 architectures only but no customisations have been made in mongo so any local installation would do the job if for some reason required on a different architecture.

    For a standalone, raspberrypi-based installation, redis (e.g. egeoffrey-database) is and will be the way to go. Just to share a data point, in my local deployment with 180 sensors configured, the database size (and hence memory utilization) is still below 40 Megabytes and I'm retaining 3+ years of data.
