Hi All,
Several years we started the company www.watt-now.com, where we started with the idea to use meters based on OEM.
Later, we decided to produce our own pi shield with more advanced measurements using a dedicated energy measurement chip (ADE 7880) and all connectivity included; since we already used a pi for each Emon meter anyways.
In the end, our company switched to focus on energy planning software and we let this shield project for 95% unfinished. The hardware is designed and tested, we only have to make some final adjustments to a custom version of the EmonHub software running on the raspberry pi>
We do not have the time or people to continue with this, so we offer the whole package (designs plus test kits) for free for anyone who would like to finish this very nice product!
Let me know when you are interested! Then I can share some foto’s and the PCB designs with you.
Best regards,
Jim
