Connect sensor

Example of work is in the video:

Requirements

Service is running on Raspberry Pi and contact the smart plug via zigbee protocol.

Zigbee stick

If you have JetHome USB JetStick Z2 it already has necessary firmware so you don't need to flash it. But if you have another adapter firstly you need to flash it with zigbee2MQTT software. You can find instructions for you device here.

Connect the adapter and verify the adapter address (it also may be /dev/ttyUSB1):

$ ls -l /dev/ttyUSB0
crw-rw---- 1 root dialout 166, 0 May 16 19:15 /dev/ttyUSB0

You might need to get access to the USB port first. Add your user to dialout group (it works for ubuntu, but the name of the group may be different on other OS). For ubuntu:

sudo usermod -a -G dialout $USER

For arch:

sudo usermod -a -G uucp $USER

Then logout and login or restart the computer.

Installation

Clone the repository:

git clone https://github.com/makyul/robonomics-carbon-footprint.git
cd robonomics-carbon-footprint

Configuration

Go to data/configuration.yaml and set permit_join: true:

# Home Assistant integration (MQTT discovery)
homeassistant: false

# allow new devices to join
permit_join: true

# MQTT settings
mqtt:
  # MQTT base topic for zigbee2mqtt MQTT messages
  base_topic: zigbee2mqtt
  # MQTT server URL
  server: 'mqtt://172.17.0.1'
  # MQTT server authentication, uncomment if required:
  # user: my_user
  # password: my_password

# Serial settings
serial:
  # Location of CC2531 USB sniffer
  port: /dev/ttyUSB0

Also you might want to fill fields server and port with corresponding information. In server field use the IP of the docker0 bridge to establish the connection: 

$ ip a                                                 127
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

...

5: docker0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default 
    link/ether 02:42:0d:ff:5f:a3 brd ff:ff:ff:ff:ff:ff
    inet 172.17.0.1/16 brd 172.17.255.255 scope global docker0
       valid_lft forever preferred_lft forever
    inet6 fe80::42:dff:feff:5fa3/64 scope link 
       valid_lft forever preferred_lft forever

Here your address is 172.17.0.1.

Then create file config/config.yaml with following information and set your location (you can look up to https://countrycode.org/ for 3-letters ISO-code):

location: RUS
service_address: 4GdHeLbmio2noKCQM5mfxswXfPoW2PcbpYKKkM4NQiqSqJMd
twin_id: 5
sending_timeout: 3600
broker_address: "172.17.0.1"
broker_port: 1883

Connect Plug

First run:

docker-compose up

To switch to the pairing mode on plug long press the power button for a few seconds until the light starts flashing blue rapidly.

In logs you should see now your plug started publishing to mqtt.

After pairing

If you don't wont to let other devices to pair with your stick, now you should go to data/configuration.yaml and set permit_join: false. Restart service (use 'Ctrl+C' and 

docker-compose up

once again to submit changes).

Running

At first start the account for the plug will be created.

If you already have an account you should add its seed to config.config.yaml file in device_seed section:

location: RUS
service_address: 4GdHeLbmio2noKCQM5mfxswXfPoW2PcbpYKKkM4NQiqSqJMd
twin_id: 5
sending_timeout: 3600
broker_address: "172.17.0.1"
broker_port: 1883
device_seed: <device_seed>

After creating account you will see the address in logs (seed will be added to config/config.yaml):

plug               | Generated account with address: 4GuP82BMAgrbtU8GhnKhgzP827sJEaBXeMX38pZZKPSpcWeT

You need to transfer some tokens to this account for transaction fees, you can do it on Robonomics Portal.

Service will see that you have enough tokens, in logs you will see:

plug               | Balance is OK

Service will see mqtt messages from the plug and safe power usage. Every hour (you can change timeout in config/config.yaml in sending_timeout section, timeout is on seconds) it will create datalog with the following information:

{'geo': 'RUS', 'power_usage': 1.021237391233444, 'timestamp': 1644494860.5860083}
