I need help with ESPHome sensor

ESPHome
1

Hello, I have a battery powered multisensor with ESP32 (PIR, sound, temp, humidity, battery, CO2).
What I want to do in the sensor yaml file is something like this :

  • Esp32 is in deep sleep for let’s say 30sec.
  • When is waking up from deep sleep to turn on the pir sensor power(this is already done for 5 seconds) and if the PIR sensor feels movement to go further with other tests(battery, temp, humidity,etc) and also to connect to WIFI and to send the values and deep sleep … if PIR doesn’t feel any movement (in that 5 seconds of being awake) to go to deep sleep again instantly (without turning on WIFI, scanning wifi networks and stuff) to save the battery.
    Can you help me to implement this “if - that - else” ?

This is my yaml file:

esphome:

  name: officesense1

  friendly_name: officesense1

  includes:

    - "cm1106.h"

  on_boot:

      priority: 250    

      then:

        - switch.turn_on: PIR_power        

        - delay: 5s

        - switch.turn_off: PIR_power

I’m not sure you can force those sensors to be manually update only.

If I was designing something like this I would use a 3.3V PIR to trigger the interrupt pin on an ESP32, to wake it out of long term deep sleep. Have a read about ESP32 Wakeup Pin Mode.

I have seen other suggestions for an ESP8266 where the PIR trips a transistor circuit to latch power on. A quick google found this discussion: PIR sensor only to be powered and it turns on another power supply and load.

I personally would go with the wakeup pin. That’s how my mailbox sensor works.
