Our Spanish partner Colaborativa organised an online workshop during the September 2020 CityEngage Week in Limerick for those interested to learn how to make and use open hardware home energy monitoring devices. The workshop focused on preparing the participants to start measuring energy usage in their own homes, sharing data within their community and experimenting with these devices. The event was also aimed at bringing together members of the public with an interest in potential shared uses of the data generated. The event brought together 25 participants.
