As far as power consumption goes, they are stupid low. Without GPS, and with boosted gain turned off, I get over 3 days on a device with a 700 mAh battery and the NRF52840 chip. The ESP32 devices use quite a bit more power, but all of these nodes are easily chargeable with a 5W solar panel.

You can put up a node on a tower with like four 18650 batteries and a five watt solar panel and the damn thing will never die until its damaged by the elements like lightning.

This sounds really cool actually. I'd be interested I'm acquiring some cheap for simple device to device and low bandwidth communications. Weather stations, time keeping servers, intercoms and things like that.

It's text and data only, no voice. So, depending on what kind of intercom you mean, it might not work for that. But weather stations and other sensors like that, it's perfect for.
