Using a binary sensor to sleep and wake an ESP32 rather than time

[Mahko_Mahko]

Are you using a cheap esp clone by chance?

How are you powering it? Try the best supply and cables you have. Are you connections soldered? How long are your wires?

You could try adding a on_boot delay (and wire begin if using I2C).

I2C bus scan after deep sleep recovery

I found the working config: on_boot: priority: 600 then: - lambda: |- Wire.begin(); delay(100); It was important to set the priority at 600 (the power up of the enabling pins had a highest priority).

You could also try this.

Is there some way to delay setting up a sensor, is that setup_priority?

I was curious about this and searched the ESPHome Discord for it. It seems some people are using it like this: sensor: - platform: am2320 setup_priority: -100 address: 0x5C temperature: name: "temp02" humidity: name: "humi02" update_interval: 60s I couldn’t find anything on a quick docs check.
