#Mqtt enter deepsleep code
I then removed the millisecond timer code that repeated the loop and put all the loop code in Setup then added the deep sleep command at the end of setup.
#Mqtt enter deepsleep free
Defining the connection The MQTT broker we use for this example is shiftr.io, you can get a free account with them if things are starting to get serious. I implemented the tutorial as written on a esp8266 D1 mini board and it worked just fine. So, there seems to be a difference between entering sleep from rule command and doing it from config menu. In this post we will utilise the same mechanism, the ESP8266 will perform the deep sleep and only wake up every 2 minute to read the temperature and post the result to MQTT broker. But after 20 sec, when it's supposed to wake up again, current goes up to 13mA and device is never booted.! sleep when a MQTT message on the topic livingroom/otamode is received. I was trying to read about this but couldn't get a good answer. Once readings have been sent, the ESP8266 goes into Deep Sleep for 10mins. I have an ESP8266 connected to a BME280 that sends weather readings to my HomeAssistant via MQTT. Properly disconnecting from the MQTT Broker is nice, especially with out a Last Will and Testament and properly closing the network connection is an OK thing do. Apologies if this is a bit of a stupid question, however I have been struggling with it for a while now. I saw a lot of posts about sending mqtt messages from an esp32/esp8266 with deep sleep between the sending cycles. When deepsleep command is executed, current goes down to 0.2mA again. The deepsleep component can be used to automatically enter a deep sleep mode on. You should properly disconnect from the MQTT broker and WiFi before deep sleep. programming allows for quick and easy transmission of the data to an MQTT server. Also once you enter Deepsleep you switch of your WiFi connection, no chance of receiving data. I have a rule script that on MQTT#Connected, publish the temp on mqtt and then enter deepsleep, 20. send them to a central unit or to the cloud and enter deep sleep. Once you enter deepsleep the processor will not be woken up by anything but the reset pulse after the deepsleep time expired. I then tested another approach, disabled deepsleep in config menu and in stead entered deep sleep by command in rule set. Sleep/wakeup worked as expected though! I could see with multimeter that during normal operation, current is between 70-80mA and during deepsleep it's down to approx 0.2mA.
Played around with different awake/sleep times, but could not get a stable result. The goal is to boot up, publish temperature on mqtt and then sleep for a couple of minutes and repeat.Īt first, I enabled deepsleep from config menu.
