The 470 Ohm (or 1K) resistor also works, but it depends on the neighboring component values. It is also possible to wake up from predefined sleep time esp.deepsleep(time). With this configuration it is possible to wake up the mcu from esp.deepsleep(0) by either pressing the tact button or by opening the magnetic switch. * SOLUTION: The trick is to add a (schottky) diode between the RST and GPIO16 (see updated circuit). Is it necessary for ESP8266-07 (or 12) to connect GPIO16 to RST (like we do for esp-01) in order to be able to use the deep sleep function for a predefined time period? Could someone propose how the ESP07 should be connected correctly? There is a lot of contradicting info on the Internet. Of course after disconnecting GPIO16 from RST, it is not possible any more to wake up from a predefined period deep sleep (in case that this is needed), e.g. I suppose that the GPIO LOW is not low enough to reset the mcu, because RST is pulled up to VCC. I realized that it is impossible to wake from ESP.deepSleep(0) using the magnetic reed switch, except if I disconnect GPIO16 from RST. GPIO16 connected to RST in order to wakeup from deep sleep.tact buttons in order to be able to flash the mcu with the same board.Powering the ESP from a separate 3.3V source connected to the 3.3V pin and GND will solve this issue. GPIO0 and GPIO2 pulled up with 4k6 or 10k resistors This may interfere with deep sleep on some devices and prevent the ESP from waking when it’s powered through its USB connector.VCC and CH_PD pulled up with 4k6 or 10k resistors.Based on my previous ESP8266-01 experience I have: Then the MCU wakes up, connects to the Internet and sends a message.Ībove you can see my circuit schematic. The concept idea is to have the MCU in deep sleep forever until it is reset by the reed switch. Long story short, I am building an ESP8266 based mailbox sensor, loosely following the post found here. However, since my goal is to adapt this sensor for uses with the MySensors library I thought I could try finding some support here also. This action makes the given deep sleep component enter deep sleep immediately.This is mostly an ESP8266 related question. Use observe the state changes of a pin using deep sleep and the ON/OFF values last longer. ![]() Then re-configure deep sleep to wake up on a LOW signal and vice versa. INVERT_WAKEUP: When deep sleep was set up to wake up on a HIGH signal, but the wakeup pin is already HIGH, Or in other words: defer theĪctivation of the deep sleep until the wakeup pin is no longer active. KEEP_AWAKE: Keep the ESP32 awake while the wakeup pin is still active. IGNORE (Default): Ignore the fact that we will immediately exit the deep sleep mode because the wakeup When the deep sleep should start? There are three ways of handling this using the wakeup_pin_mode option: To tell ESPHome how to handle: What if the wakeup pin is already in the state with which it would wake up However, there’s one scenario that you need On the ESP32, you have the option of waking up on any RTC pin. Only one deep sleep component may be configured. Must be one of ALL_LOW (wake up whenĪll pins go LOW) or ANY_HIGH (wake up when any pin goes HIGH). ![]() Mode ( Required): The mode to use for the wakeup source. Pins ( Required, list of pin numbers): The pins to wake up on. This cannot be used together with wakeup pin. Id ( Optional, ID): Manually specify the ID used for code generation.Įsp32_ext1_wakeup ( Optional): Use the EXT1 wakeup source of the ESP32 to wake from deep sleep to The wakeup pin is already in the state with which it would wake up when attempting to enter deep sleep. Specify how to handle waking up from a wakeup_pin if Wakeup_pin_mode ( Optional): Only on ESP32. Use the inverted property to wake up to LOW signals. Wakeup_pin ( Optional, Pin Schema): Only on ESP32. To wakeup from a touch event, Binary Sensor must be configured properly. ![]() Use a touch event to wakeup from deep sleep. Touch_wakeup ( Optional, boolean): Only on ESP32. Sleep_duration ( Optional, Time): The time duration to stay in deep sleep mode. Touch_wakeup_reason ( Optional, Time): run duration if woken up by touch. Gpio_wakeup_reason ( Optional, Time): run duration if woken up by GPIO. ![]() Only on ESP32, instead of time, it is possible to specify run duration according to the wakeup reason from deep-sleep:ĭefault ( Required, Time): default run duration for timer wakeup and any unspecified wakeup reason. Run_duration ( Optional, Time): The time duration the node should be active, i.e. In these cases, using a USB to TTL adapter will allow you to log ESP activity. This may interfere with deep sleep on some devices and prevent the ESP from waking when it’s powered through its USB connector. This enables the flasher to reboot the ESP when required. D1 mini) on the chips’ control line that is connected to the RST pin. Some ESP8266s have an onboard USB chip (e.g.
