## Summary

Dave Jones and Chris Gammell discuss home energy systems, including Chris's Tesla Powerwall and Dave's battery rack issues, alongside the broader challenges of solar grid integration in Australia and the US. They analyze the design and manufacturing of a weird A&M 626 multimeter, speculating on its tooling origins. The conversation shifts to Dave's new timer project, debating microcontroller choices like the ESP32 versus ESP32-C3 and firmware platforms like Arduino versus ESP-IDF for low-power applications.
