Suggestion for deep sleep/firmware flash/long sleep #310
Description
In order to flash new firmware, the device needs to stay on. I have done this with a helper switch in Home Assistant and this code:
binary_sensor:
- platform: homeassistant
id: stay_awake_bool
name: Stay awake sensor
entity_id: switch.seeedstudio_stay_awake
on_state:
- logger.log:
format: "********** stay_awake bool turned ON/OFF ! ***** stay_awake=%s, prevent deep_sleep "
args: ['id(stay_awake_bool).state ? "true" : "false"']
- if:
condition:
binary_sensor.is_on: stay_awake_bool
then:
- logger.log: "Deep Sleep PREVENTED (Sensor)"
- deep_sleep.prevent: deep_sleep_control
else:
- logger.log: "Deep Sleep ALLOWED (Sensor)"
- if:
condition:
lambda: "return id(is_new_flash);"
then:
- logger.log: "Deep sleep still prevented because of first startup after flash"
else:
- deep_sleep.allow: deep_sleep_control
internal: false
entity_category: "diagnostic"
script:
- id: enter_deep_sleep
then:
- logger.log: "Entering deep sleep strategy..."
- if:
condition:
binary_sensor.is_off: stay_awake_bool
then:
- delay: 0.5s
- logger.log: "Slaap nu"
- deep_sleep.enter: deep_sleep_control
else:
- deep_sleep.prevent: deep_sleep_control
- logger.log: "Niet slapen!"
The first time a new firmware is flashed, the device needs to be on for more than 1 minute in order to prevent a revert to the previous software version. I have done this this way:
globals:
- id: firmware_fingerprint
type: uint32_t
restore_value: True
initial_value: '0'
- id: is_new_flash
type: bool
restore_value: False
initial_value: 'false'
script:
- id: enter_deep_sleep
then:
- logger.log: "Entering deep sleep strategy..."
- if:
condition:
binary_sensor.is_off: stay_awake_bool
then:
- delay: 0.5s
- logger.log: "Slaap nu"
- deep_sleep.enter: deep_sleep_control
else:
- deep_sleep.prevent: deep_sleep_control
- logger.log: "Niet slapen!"
- id: manage_run_and_sleep
mode: restart
then:
# Controleer of dit de eerste boot is na een flash
- lambda: |-
// We maken een uniek getal op basis van de compile-tijd string
std::string version_str = __DATE__ " " __TIME__;
uint32_t current_hash = 0;
for (char c : version_str) {
current_hash = ((current_hash << 5) + current_hash) + c;
}
if (id(firmware_fingerprint) != current_hash) {
ESP_LOGW("CUSTOM", "Nieuwe firmware gedetecteerd! Hash: %u", current_hash);
id(is_new_flash) = true;
id(firmware_fingerprint) = current_hash;
} else {
ESP_LOGI("CUSTOM", "Firmware is ongewijzigd.");
id(is_new_flash) = false;
}
- logger.log: "Waiting for sync..."
- wait_until:
condition:
- and:
- api.connected
- lambda: 'return id(ha_time).now().is_valid() && api_is_connected();'
timeout: 15s
- component.update: up_time
- wait_until:
condition:
lambda: |-
return id(sensor_temp_slaapkamer_temperature).has_state() &&
id(weather_cond_day0).has_state() &&
id(weather_cond_day4).has_state() &&
id(weather_high_day4).has_state() &&
id(stay_awake_bool).has_state();
timeout: 15s
- delay: 3s # allow sensors time to update
- component.update: epaper_display
# check of het een eerste opstart is na een flash
- if:
condition:
lambda: 'return id(is_new_flash);'
then:
- logger.log: "flash boot mode: ESP will stay on for 1.5 minutes for updates/logs."
- deep_sleep.prevent: deep_sleep_control
- delay: 90s
- logger.log: "flash boot mode done, deep sleep cyclus."
- deep_sleep.allow: deep_sleep_control
- lambda: 'id(is_new_flash) = false;'
else:
- logger.log: "NORMAL MODE: short wake display update."
And for the check if it is the middle of the night and longer sleep is wished for:
# Check of het nacht is (tussen 23:00 en 07:00)
- if:
condition:
lambda: |-
auto now = id(ha_time).now();
return ((now.hour >= 23 || now.hour < 7) && !id(stay_awake_bool).state);
then:
- logger.log: "Het is nacht. Scherm wordt niet geüpdate. Slaap tot 07:00."
- deep_sleep.enter:
id: deep_sleep_control
until: "07:00:00"
time_id: ha_time
else:
- logger.log: "Het is dag. Normale cyclus."
- script.execute: enter_deep_sleep
