YoLoPy

A LoPy device being polled by a Raspberry Pi, which in turn tweets the Lopy's Uptime every 8 hours

Architecure

Running on a noname PowerBank, nominal rating 2200 mAh
Connected to home wifi router via changed "boot.py"
Runs a simple script in "main.py" that increments a counter every 60 seconds and writes current value to local file "data.txt"

Kludge of Cron Jobs & Python scripts to:
FTP-pull latest "data.txt" from LoPy
Compare to previous version and check if there was a change
Crontab every 8 hours to run a Twitterbot to Tweet the latest If there was a change http://www.makeuseof.com/tag/how-to-build-a-raspberry-pi-twitter-bot/

Recommended to have serial UART working in case the WLAN connect in "boot.py" fails and leaves you without IP access. (with serial UART shell you can then just Factory reset the filesystem https://docs.pycom.io/lopy/lopy/tutorial/reset.html#factory-reset-the-filesystem - without you will have to fiddle with the firware reset pins)
FTP transfer "boot.py" to /flash folder (overwrite) = WLAN connect - I had to use filezilla and force passive/PASV mode
ONCE the WLAN to your home router works - FTP transfer "main.py" to /flash folder (overwrite) = loop to write the file every 60 seconds
Reboot

Test with "wget -t 1 --user=micro --password='python' ftp://192.168.2.140/flash/data.txt" TODO: use curl instead

Upload Python script TODO
Add Cron Job in CRONTAB TODO

First experiment with LoPy
See how long it lasts - assumption is that devices will get smaller, so a coin sized assembly in a few years should have uptimes in the same order of magnitude
DISCLAIMER: This project completely ignores the LoRa technology, could be done with any other 'duino or similar

The LoPy is a Wifi and LoRa enabled programmable device https://www.pycom.io/solutions/py-boards/lopy/
If you don't know what a Raspberry Pi is, you probably shouldn't be reading this.
