After both the #compteurconnect and the #blockfest hackathon, it is time for us to build stuff related to a local and concrete experimental context. That's how the DAISEECamp #1 was build: in order to define in which context and how the current DAISEE development can interact with the local relality of the ground.

As a result, we found a potential experimental ground with a local (near Lyon) group of households including Louis' father house. The documentation (in French for the moment we do are sorry about that) can be found HERE.

The experimental context ground

An picture is far more representing than a bunch of words...

Basically, the set of houses are located remotely from the town in the country side with some really interesting assets for experimentation :

• First Louis' father is already committed to experimentation int he field of energy, agriculture and a lot of things related to sustainable development

• Secondly, the house is well set for experimentation of the DAISEE program since it already gather : 3 independent sources of solar electric production, 3 independent sources of local consumption (which means : 3 production meters and 3 consumption meters).

Note: The UPS can be connected via Bluetooth. Unfortunately, the bluetooth module is not installed, and it is not possible to get back the date via bluetooth for the moment.

Moreover, there is a local project about building a distributed solar powerplant divided around 10 site of 9kW each.

What is energy and what do we want to do here with DAISEE

The aim of this session was to clarify what energy is, what are the interest of the contributors in the DAISEE program and what are the next steps.

What we've done during this Camp

• Test the Open Energy Monitor on site

It turns out that data from the EmonPi (OEM) does not seem relevant. Even if the EmonPi is not connected, is still mesure a 34W power. It can be the sensibility (noise) of the sensor. We have to check if an AC/DC adaptor can improve reliability.

• Take some time with Louis' father to discuss the needs and understand into details the photovoltaïc solar panel installation and use chain : from first contact with the contractor to the electric production and invoicing to the electricity buyer. We gathered a lot of data and sources that helped us to understand where DAISEE can add value for both the consumer and the contractor/buyer/distributor.

Discussion about the DAISEE's orientations

This camp was also the opportunity to discuss the relevance of the blockchain technologies for he DAISEE project.

It turns out that the blockchain technologies are part of the solution but have current limitation that make them not fully relevant for the energy sector. Some points are:

• Real time data management on a blockchain is really limited from both the validation time of a block, the size of the blockchain and the necessary fee for each transaction (that can add-up to really costly overall fee)
• Identity management and securing the viability and relevance of the energy data that are collected
• It's relevant for transaction and automation of the processes
• It will require to be hybridized with other technologies related to data storage (IPFS for instance) and database management (BigChainDB for instance)
