ESP Easy with disabled wifi (battery and deep sleep)

[tuxmartin]

Hi, I need to build WiFi thermometer for heating control with one DS18B20 temperature sensor.

I would like to use only ESP8266 ESP-12, 18650 battery and DS18B20 sensor.
I read about project with 3 Ikea AA alkaline batteries and DHT22. It use deep sleep and wake up every 1 minute and send data over wifi. It works 55 days!

I would like to improve it. Use deep sleep and wake up every one minute. After wake *not enable wifi and connect to ap*, only read data from ds18b20 sensor and compare it with previous value. If the last and current values difference is great than 0.25°C, connect to AP a send data. Otherwise sleep for next minute. And every 15 minutes send data.

Is it possible with ESP Easy (and how?) or I need to use plain Arduino?

55days is very nice... i made a plugin to use modemsleep function, it means that cpu remains active, but stops wifi. I think that after resuming the deep sleep the first command can be "modemsleep,1", and when you wan to connect "modemslep,0" but i have never used it combined with deep sleep.

55 days not with 1 minute interval, but 5 minute DeepSleep interval...

"hodnota 300000000 je právě zmíněnných 300s (5minut), po které bude ESP8266 v Dsleep módu."

I speak czech too )

So with your 15 min interval it will be theoretically cca 3x50 days

Than you for sharing this thread this is very helpful for everyone.

Any updates on this? Were you able to build this? I am looking to do the same.
