We have recently made a new GitHub repo didicated for GGreg20_V3 + generic ESP32 with pulse counter GPIO debounce in microseconds up to SBM20 GM tube's deadtime (190us). And tested this yaml-config on an ESP32 Wroom (NodeMCU-like module) and used GPIO23 as a pulse counter input. Previously, we did not notice that the ESPHome Pulse Counter API has the ability to apply a low-pass filter. We hope that this example will help many users to counteract the bounce that can sometimes occur in GM-tubed and high voltage systems.
