ESPHome Sensor Delay – How to Reduce Response Time?

Hi everyone,

I’ve set up an ESPHome configuration for a motion sensor, but I’ve noticed a slight delay in response time when triggering automations. It takes about 1-2 seconds before the action executes, which isn’t ideal for my setup.

I’ve tried:

  • Lowering the update interval in the YAML config
  • Testing different Wi-Fi signal strengths
  • Using a faster microcontroller (ESP32 instead of ESP8266)

Has anyone found a way to make ESPHome sensors react instantly?

Thanks!

You’ll need to work out where the latency is by looking at the logs a bit closer. Synchronise the ESP to an NTP and then compare it to the HA logs. I’d guess that it’s probably not in HA, it’s likely to be transport/WiFi latency due to the device connection time and maybe channel noise from other devices.

They usually do. On Esphome.
Do you mean in home assistant?

What sort of motion sensor?

Share your device configuration. Otherwise we’re just guessing.
