This way, you can configure the device to wake up the second you hit the button: Instead of using a switch, let’s use a button connected between ground and pin #4. This requires you to use one of the pins that is wakeup-enabled, so I’m using pin 4 instead of pin 5. How about instead of a switch, since it’s going to always be a little bit weird, we use a button? While we’re at it, let’s use a feature of the ESP32 that lets you trigger the device to wake up. Once you disable sleep, it’s disabled until the device reboots, which means that the physical switch lies to you.ĭeep sleep method 2: Controlling deep-sleep by a button.It won’t prevent sleep until the device wakes up to process the message.This has a few quirks, which may or may not bother you: On_press : then : - logger.log : "Prevent deep sleep" - deep_sleep.prevent : deep_sleep_1Ĭaptive_portal : # Enable logging logger : # Enable Home Assistant API api : ota : Name : "Defeat" id : "defeat" pin : number : 5 mode : INPUT

} wifi : # Wifi details go here deep_sleep : run_duration : 30s On_boot : priority : -100 then : - logger.log : "Checking sleep" - lambda : |. Therefore, the on_state action doesn’t fire while the device is asleep and you need to use an on_boot event to check the button at startup. Remember, it costs resources to store the actual state of anything between resources.
Esp32 exit deepsleep how to#
The big thing that I discovered, other than butting my head against how to write actions, is that it’s a little tricky to have the state of your ESPHome device change while the device is sleeping. Thus, I took a SPDT switch, connected one side to ground and the other side to 3.3v, and then connected that to pin #5: If the switch is on, deep sleep is pervented. My first thought was that I’d like to just have a switch.
Esp32 exit deepsleep manual#
The manual describes how to use MQTT to accomplish this goal Deep sleep method 1: Controlling deep-sleep by a switch Deep sleep method 0: MQTT as per the docs If you want deep sleep on the ESP8266, you need to connect a cable from GPIO16 to the RST pin.

A quick note about deep sleep on ESP8266 and ESP32 devices I ended up grabbing a bunch of help from oskar & ssieb from the ESPHome discord to figure this out. The only documentation is for how to use MQTT to disable deep sleep, so I decided to explore how to make this work.
Esp32 exit deepsleep update#
You can’t trigger an OTA update while the device is in deep sleep. If you get your ESP into deep sleep, pretty much everything is shut down and stopped and so the power usage is dramatically reduced. It’s great to be sitting at my desktop pushing updates to the actual device without juggling cables and stuff. Less than a Pi, but still enough power to matter if you are using solar power.įurthermore, I think that ESPHome’s over-the-air software update system is amazing. Thing is, either of those devices eats up quite a bit of current. I’ve been wanting to do some stuff with solar power and low energy and ESPHome.
