Yup, it does. Seems I need write access to publish branch for pull request. Or am I doing it wrong? Anyway - here are the Libs in zip. [SOIC-BITE-Diptrace.zip](https://github.com/SimonMerrett/SOICbite/files/7597916/SOIC-BITE-Diptrace.zip)

Hi. Yup, that's what I thought, but I could not reproduce it. Perhaps you have P/N for the contactor that caused it? I could order it then, add hardware fix...

Hi. In case anyone wants to do so - feel free to optimize it and I can merge if your branch will work. As it works and I am not...

Cool, Thanks @rharrison. I'll verify that it still works on a devkit and update. Sorry for being so slow, much work backlogged.

> Can you also upgrade a v2 controller with the v3 software? Short: No. Long: v2 runs on Microchip PIC MCU, v3 uses Esperessif ESP32 - one is small 8...

I'll look into that. I've used voltage divider + Zener diode to ground connected to one of SSR pins configured as input with interrupt attached. Handler pretty much mimics same...

Here's an idea. Using one gate 74125 circuit powered from 3.3V, A tied to GND, Y goes to ESP CP pin and /OE goes to resistor divider + 3.0V Zenner...

So waht I just tested in hardware and what worked: * I've changed the series resistor for tank capacitor - now it's 30 times smaller and on the output of...

Oh, and also external devices (sensorbox, etc) should be powered before the diode, so they would not drain the tank cap...

One more thing - if you use the diode after the 220V PSU and power the RCD before it, RCD will fail immediately after power loss so if always used...
