Hardware Link for COO

Energyweb link is a hardware oriented project to integrate energy assets to the Origin DAPP.

It is currently deployed on x86_64, arm64 and armv8 architecture devices using balena.io. The devices logs carbon emission and generated/consumed power data into certificate of origin smart-contracts.

Origin App

1. Read or Create PERSISTENCE path pointed at core\helper.py.
2. Open and parse the designated configuration file.
3. Instantiate classes by reflecting the objects in the config file.
4. In case of failure on steps above throws.
5. Log configuration.
6. Schedule measurements.
7. Wake up and try to read from input modules.
8. Log success or failure.
9. Create and sign a transaction to the designates smart contract.
10. Try to reach blockchain client and send the transaction.
11. Log success of failure.
12. Back to step 6.

Deploying on hardware

For a decentralized network infrastructure, it is fundamental that every power generating site runs and maintains its energyweb client, providing all participants the ability to be independent and part of the consensus regarding the state of the smart contracts it runs.

To facilitate the deployment and updating of these devices we use a continuous integration and fleet management platform.

Requesting access and burning the SDCard

1. Artik710 development kit board. Buy it on Mouser. Or Raspberrypi v3 with python 3 installed.
2. Ask EWF Ramp-up team for OS images.
3. Burn the image using dd or etcher.
4. Follow the official guide to update the MMC and boot from it.

Stepping stones

1. Blockchain client. For EWF Tobalaba test chain try one of the flavors below:
   1. Energyweb client installed and running.
   2. Parity v1.10.8 or later with parity --jsonrpc-apis all --reserved-peers /assets/tobalaba-peers --chain tobalaba.
   3. Docker version of Parity docker run parity/parity:latest --chain tobalaba --jsonrpc-apis all.
   4. More stable Docker version of Parity, change directory to ewf-client\ and run docker run -v $(pwd):/data parity/parity:v1.9.3 --jsonrpc-apis all --reserved-peers /data/tobalaba-peers --chain /data/chain.json.
2. COO contract deployed on the designated blockchain.
3. Check the transactions on the block explorer.

Using this repository:

• create a new project in resin.io
• select artik710, add a new device, download the image
• follow the instruction on screen to flash your device,
• after your device is available on the dashboard, open your terminal fo some cli fun.
• change to this repository folder and run git remote add resin <USERNAME>@git.resin.io:<USERNAME>/<APPNAME>.git with your resin.io credentials.
• run source ./sendToResin.sh. You should now see the resin.io unicorn on your terminal.
• your device should start updating with the code you deployed.
• on the dashboard open your device, then open the Service Variables tab.
• create a variable for origin-producer named producer with the configuration file written in one line.
• create a variable for origin-consumer named consumer with the configuration file written in one line.
