collectd is an open source monitoring system which can record to e.g. RRD flat files or SQLite and can forward collected metrics to SIEM-like monitoring and charting and anomaly detection apps like Grafana or InfluxDB.

Nagios has "state flaping detection" to prevent spurious notifications.

collectd-python-plugins includes Python scripts for monitoring humidity and temp with i2c sensors and Python: https://github.com/dbrgn/collectd-python-plugins

There are LoraWAN soil moisture sensors, but they require batteries or an in-field charging method

Thanks so much for sharing these resources—this is fantastic!

If you’re into LoRaWAN, you might be interested to hear that we’re also developing an industrial composting monitor that incorporates LoRaWAN tech. Here’s the promo video link if you’d like to check it out: https://www.youtube.com/watch?v=TZFiiwLhZh8&feature=youtu.be

    Can your sensor product feed data to open source software for hobbyist and professional agriculture?

    I set up FarmOS in a container once; the PWA approach to the offline mobile app was cool but I guess I wasn't that committed to manual data collection or hobbyist gardening.

    Are there open standards to support architectural sensor data?

    Where is the identifier on the sensor? How does the user scan the visually-confirmable sensor barcode or QR code or similar and associate that with a garden bed or a container?

    How does it notify of low battery status; is there a voltage reading to predict the out of battery condition?

    Is there a configurable polling interval?

    How do I find a sensor unit with a dead battery; is there a low-power chirp, or do I need a metal detector or very directional wireless sensors and triangulation or trilateration?

    Are there nooks and crannies in the casing?

    How to replace the battery?

    Can they be made out of compostable materials? E.g. carbon with existing nanofabrication capabilities

    After Single Walled Twisted Carbon Nanotube batteries which are unfortunately still only in the lab, and more practically Sodium Ion, which batteries can safely be discarded or recycled in the agricultural field?

    LoRaWAN may be more economical than multiple directional long range WiFi antenna like can be found on YouTube. https://news.ycombinator.com/item?id=22735933
