TLDR
zigbee based energy monitorying system.
A gateway deivce (ESBOX) gets sent data from each zigbee meter attached to the network.
The ESbox packages the data to a JSON message, and sends it to the listed web server.
The Listed web server waits for ES box to reach out, receves the JSON and closes the connection, ready for the next message.
hardware:
- zigbee energy meter
- zigbee-ethernet gateway (from here on known as 'ES box')
- VM running pyhton twisted web server
software
- zigbee-ethernet gateway runs software that packages the data and sends it on its way.
More indepth.
The ES box sends a "config" to the energy meter over zigbee with its reporting paramaters, (time, if change is X then report, etc etc).
The ES box then recives readings from the meter and stores it locally in a DB ready to be sent to the server.
The ES box reaches out to the server every 'X' time, and if everything is "ok" it sends the message(s) to the server.
If more then 1 energy meter is connected to the ESbox, the readings will be sent in a new message.
The example server "twisted_server" is a basic script using twsited internet to wait for an ES box to check in.
Once a connection request is receved, it will:
confirm that it receved it.
send any updated configeration files (if any).
request the latest readings.
Once readings are recived, it will close the connection, and wait for the next message.
The 'twisted_server.py' imports 'messages8344' as the instructions, these are needed to communicate with the ES box.
The end goal is to receve the JASON data, and put it in a time series DB,(influx),
Idealy, handle the data in such a way that mutiple ES boxes with mutiple meters can communicate with the server, and have the data stored correctly.
-Data to be entered to DB as follows.
-ESbox serial
-xyz
-Meter IEEE (mac address)
-abc
-Readings
-Volts
-Amps
-etc, etc
See file, raw Json for a output of the script, and a raw JSON message.
Twisted_server is original example from manuafacutre.
Test_server is what i am attemping to make work.
working script in writetodb.py
