Measuring internal temp of oysters and mussel

[amotl (Andreas Motl)]

Dear Daniel,

thanks for sharing such detailed information about your project. Good luck with everything!

Referring to all topics would require a really extensive answer, so I would like to pick just two things out of the topics you are listing which might help you and your colleagues.

Power

@OysterLemur

I also thought about a solar power bank, but at least with my cheap eBay one, when the node goes to sleep, the power bank cuts power and as a result the node does not have power to wake up (or at least that is what I think is happening).

This is exactly what is happening.

@clemens

All “Powerbanks” have a switch-off mechanism that disconnects the LiPo when not in use. Unfortunately, the minimal power consumption in sleep mode of the FiPys or Arduinos is below the threshold and so the power bank turns off.

Data management

About

We might have conceived the backend system of your dreams already by building an accessible open source data historian within the Hiveeyes Project. While originally built for the purpose of beehive monitoring, the whole system has been designed to be operated in arbitrary environmental monitoring projects of its kind - mostly in the field of academics as we are currently doing within the Bee Observer Project.

The system cares about data acquisition from multiple measurement nodes with easy onboarding, stores measurement data in a timeseries database (InfluxDB) and yields rich visualizations by building upon Grafana.

LABS - Store and visualize data using InfluxDB and Grafana

Dear TTN community, thanks for this story! We want to take the chance to introduce you to Kotori, a full-stack FOSS data historian integrating InfluxDB, Grafana, Mosquitto, MongoDB, dygraphs, mqttwarn and more with each other. It offers multi-channel, multi-protocol and multi-tenant data acquisition and data export features and is super easy to install and operate. The system might be interesting to the whole TTN community for different tasks in the field of measurement data collection and …

Example

As data telemetry and acquisition is rather invisible, I would like to share some of our most recent efforts on the visualization side.

Enjoy visiting Hive overview & Bee weather @ ZK/U Statista. As you can see there, we are also funneling data from the national weather service into the system in order to be able to correlate observations with weather conditions.

Bottom line

Please let us know if some of the things we are working on will spark your interest.

@OysterLemur

I went to https://community.hiveeyes.org/ but had trouble finding what I was looking for given that most of the posts are in German. Any help with code or a point in the right direction would be great.

We recognize the forum is a jungle, so we are happy to help you navigate it or better pinpoint to specific software- and hardware-artefacts we are working on and which might be ready to apply them to your endeavor.

Also, I might translate content where appropriate. However, you are welcome to join the forum at https://community.hiveeyes.org/ which will enable you to use the online translation feature provided through Discourse Translator - plugin - Discourse Meta.

With kind regards,
Andreas.
