The past 2 weeks have been slow going, due to in part members having to focus on make-up exams.However we have partitioned our work somewhat, we’ve got the ESP32(wifi-enabled chips) up and running and able to transmit data which we’ll later fix up with a current sensor. 

Fixed an old wi-fi enabled raspberry pi 3b+ to work as our server after some issues with power supply and ssh, and we’re still figuring out the tech stack for database and visualization. 

We’ve done some tests with Flask, a python framework for the web: it has some issues with animated plotting, so we might look at some alternatives as animated plots would be nice for the real time current monitoring, but not as necessary for the comparison to spot prices as that updates once an hour. But it was easy to get up and running on a local server.

As of now this is quite a nothingburger when it comes to code, just using some default matplotlib code.

We expect to post weekly blogs from now on.
