Production Has Begun

Hello everyone!

Just a quick update to note that production has begin on the energy meters ESP32 PCB’s, and solar monitor adapters at PCBWay. The PCBs are already complete, and assembling the parts onto the boards has started. The custom connectors that we ordered were all delivered last week.

From here, we expect to have the assembled board in hand in about 3-4 weeks time - I’m still terribly sorry that this could not be sooner! After delivery we will begin packaging the individual board orders, and assembling/testing the kits.

If you haven’t seen already, there have been some substantial improvements made to EmonESP. Both in functionality and stability. You can keep an eye out for more updates on the project Github page. and the occasional picture on our Instagram page.

Stay tuned for more updates!
