@Lars I’m curious about your VPN setup. Mostly depends if your home is physically near the field in question.
Would the wifi router in the field be extending your home network (assuming the field is close to your home)? If so, you might want to consider modifying the VPN so it’s only required when accessing from a WAN (outside your home network). Otherwise, I would configure the router to connect to the VPN - the major advantage is that anything else you connect to the router would already be connected to the VPN and require less configuration in the future (even your phone if you connect to that wifi router when you’re out in the field)
You also might be interested in using the LoRa protocol for your sensor… if the field isn’t too far away (within 1-2km) it might be easier and cheaper! You could power a LoRa gateway at your house or barn (wherever you have power) instead of via solar panel.
Also, re: node-red, I’m interested in creating a farmOS library for node-red. Adding support for sensors would be a great (and primary) use case. Check out my post: Node-RED farmOS library - I haven’t gotten to this yet, but definitely am interested in using more node-red!!
Oh also…
Is there a easy way without learning to use mathlab or javascript to use plotly.js?
Data from sensors are automatically graphed in an embedded plotly.js graph on the Sensor asset’s page. It works quite well! I just set up auto graphing of solar data and got these graphs “for free” ! Note that right now the graphs are limited to the last 100 data points. But this will likely be changed going forward…
I’m not familiar with Weewx data feeds, but looks like it would be a great thing to support
