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.
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://youtu.be/GWq6L94ImX8
Thank you so much for these questions! For clarity, I’ll copy and paste the question for each response:
Q: Can your sensor product feed data to open-source software for hobbyist and professional agriculture?
A: Yes, our sensors can definitely feed data into open-source platforms, making them a great fit for both hobbyist and professional agriculture setups. The guide offers a helpful starting point for integration. Additionally, data collected by the sensors can be exported as a CSV through our consumer app. This makes it easy to process the information or import it into FarmOS or other open-source tools you might be using.
Q: 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?
A: Each sensor uses its unique MAC address as its name. To make setup even easier, each device features a visually confirmable barcode or QR code. Once connected, the sensor’s indicator lights confirm the connection status, so you’ll know right away when it’s properly associated.
Q: 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?
A: For low battery notifications, the device features a red indicator light that activates when the battery is running low. Additionally, you can poll the device over Bluetooth to get the current battery level.
Q: 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?
A: A low battery is signalled by the sensor’s lights turning orange, while a dead battery is indicated by the absence of flashing blue lights. If the sensor still has some power, you can poll it via Bluetooth to check its battery level.
Q: Are there nooks and crannies in the casing?
A: Yes, if you’re thinking of something specific for this — please let me know! I’m happy to chat further :)
Q: How to replace the battery?
A: Currently, the battery in our sensors is not replaceable. However, when the device reaches the end of its life, we’re committed to sustainability. We plan to offer users a significant replacement discount and take back the module and responsibly recycle it into new Montys. Interestingly, the original Monty design included a removable battery pack. Through testing, we discovered that most connectors weren’t durable enough to withstand the tough composting environment, so we shifted to a sealed design to ensure long-term reliability.
Q: Can they be made out of compostable materials? E.g. carbon with existing nanofabrication capabilities
A: We’ve trialed biodegradable plastics in the past, but we found that they degraded in the field. Instead, we’ve opted for a 100% recyclable plastic material to ensure that it is able top withstand harsh compost conditions.
Hopefully, I’ve covered everything here—if you have any further questions, just let me know!
