And what do you think of such a vibration/velocity sensor I am curious to know? Energy factor set to a threshold of 50 (amplitudes from the accelerometer) below which values I treat as noise. Overall it's STM32, 2.9 inch e-paper, Zigbee2MQTT and Home Assistant integration. I'd add that it's about non-invasive monitoring of the behaviour of various appliances like a washing machine, fridge or fan but I don't think it's appropriate 😉
Anyway, the integration with HA is nothing difficult and the real-time "measurement" is already working while the signal processing itself will be a challenge. But most importantly it has taken off
