My 2 esp:

Did have a battery drain ...
I do have problems with my WiFi router...
Only 1 day and my new battery where gone..
1 do have 2 sensors and this settings:

And the second ESP does not have any sensor on board,
And the battery empty to.....

As far as I can see, you did not tick the Sleep Mode check box.

That is correct....
Only i am afraid to lose the ESp in my webgui.....
And because my setting are in concept....

[NietGiftig]

A Pir and batteries are not the best choice.
Unless they are in rooms where there is not much movement.
Otherwise they keep sending and using the WiFi.

Sleep-mode and PIR is not a good idea, unless you make the esp wake up (reset) on movement

ESP and batteries are no good solution.
Batteries and sensors is MYSENSORS option.

mm
I thought that i read this chip was very good with battery's..
Why not.....
Is there no one that the ESP on an battery systeem?

And why do they sell them with battery pak?

Please read the answers.
Have a nice day

Sometimes you can be fooled by what people offer for sale.
The battery packs are pure for debugging for beginners.............
Google for power consumption ESP 8266 and you see they are not the best solution for battery operated sensors.
MYSENSORS is using other RF chip which is less consuming power.

Thanks.
mmm

Pity...
But if I put it in sleep mode ? Will they or last longer ? Seeking to make the smallest alternative to a pir . [ And saw the combination with Domoticz , so 1 and 1 = ...

I assumed the Battery Body it could sustain, because feed all sensors ...

If I have to feed all , I can almost buy a better sensor ..

Of course, to my sensors ...

Anyone have experience with mysensors . ?
What is the range of the gateway?

And that gateway I can flash a esp8266 ?

My esp12 run 3 motnhs from single 700mah liion cell, 30min deepsleep mode, power led removed. Cell still has 3.7V - lot of energy remaining.

[Deennoo]

Got one nude ESP12E who run with a 5v solar panel to charge 3*1.2v battery (recycling a garden light)

I test it for a parrot flower clone, actually it run since September, sending 1/h temp, lux, hum, and got back to deepsleep.

Of course i'm a beginner, but it work, great

[Dylantje]

When i use the esp in the sleeping mode....
Is the battery draine then gone???


Or what is the time the esp can work in a sleeping mode?

would be very intered in your solar setup...
may you show a picture, components (links for aliexpress? ), cabling-diagram?

great thanks,

Nothing special on it :

Solar panel and batterie come from a lidl garden lamp
Just don't forget to wire the deepsleep pin to gnd.

some info here (french forum)

[tozett]

coool, thanx.

next to me is a lidl, the spring is coming and than the solar gardenlamp in the lidl.....
i will try this

[Deennoo]

got some news,

i 'll test this how to :
http://www.whatimade.today/do-i-have-ho ... hermistor/

Without thermistor part, but using the adc pin for a soil moisture sensors, parts order today, now waiting for them

here is a great piece on power saving tips for ESP8266 on github. https://github.com/z2amiller/sensorboar ... rSaving.md

I experienced that with a 1cell lipo and a low quintessence 3.3v regulator, my 1000mAh Lipo emptied within 24h. The solution to avoid the battery to empty in deep sleep mode for example is to add a 470uF Tantal capacity in parallel to the VCC-GND connections of the ESP8266. 470uF is a minimum. It did not work with 220uF. Best is to connect the capacitor as close as possible to the ESP. Tantal is necessary to have a low ISR and be able to compensate picks that are used from the ESP when connecting the WIFI network.

P.S. I used an AP2112K3.3v Regulator as on the Sparkfun board. Works great to get 3.3V from a 1 cell lipo !

You can find some more details about a proper power supply here https://www.youtube.com/watch?v=wf_msvWv1jk

I see that the cap helps to smooth supply for the active ESP but don't understand what it does for deep sleep where current draw is about 0.1mA. What is battery life now?

Hello,

in general the ESP can be used with batteries.
That needs some specialised software, i don't think ESPEasy is the choice for this.

The little battery packs do not have enough power, they are just for quick testing.
You may use a LiIon or LiPo battery, they are rechargeable and have much more power.

It needs a specific setup: You have to connect GPIO 16 with the RST and you have to tick the sleepmode box.
The problem with your home server is loosing connection - but this can't be avoided. Sending takes power so
all battery sensors i know switch off the transmitter to save battery.
Remember that the "sensor delay" setting wakes up the circuit so the shorter the period the shorter is the life of the battery.

Last but not least:
A PIR sensor on battery is definitely a bad choice. Those modules can take up to 5 mA of current - permanently.
Even more when motion is detected. How much exactly will differ from module to module but anyways it is too much
for battery use.

Even the DHT sensors take up much current compared to others.
DHT11 takes around 1,5 mA when working and about 0.3 ... 0.5 mA on standby.
Besides that DHT11 and DHT22 are somewhat inaccurate.
If you want a low power consumption use a SI7021 for your project.
Max current running 0,15 mA, on standby 0,06 mA, so a tenth of current and higher accuracy on top.

Watch out, you can only set up one SI7021 as the I²C address can't be changed!
As a secnod sensor you may for example ad a BME280 (temp/humidity/pressure).

Anyways, battery and PIR will not work well, and a permanently running WiFi will neither.

Let's calculate a bit:
Usual AAA batteries have a average capacitiy of 380 mAh, really good ones have about 550 mAh.
Lets calculate with 400 mAh.
Your sensors alone take up around 6 mA.
400 mAh / 6mA = 66,6 h runtime!
And this are only the sensors, the ESP is not included.
My complete sensor modules with TLS2561 luminosity, BME280 (temp/hum/pressure), a DS18B20 and an ESP 8266
take up around 65 mA with peaks up to 300 mA when transmitting.

Again: 400 mAh / 65 mA = 6,15 h !!!

Standard batteries will drain within 6 hours.

A good Li-Ion battery (format 18650, 3.7V)) may have up to 3000 mAh

3000 mAh / 65 ma = 46 h

After two days even such a fat battery is drained!

As you can see there is no way avoiding sleep mode.

To clearify: Even with sleep mode you will be far away from the "one year and more" lifetime
of circuits professionally designed to ultra low power.

Edit: added calculation of runtimes, removed wrong I2C address part.

Also make sure to use good voltage regulator fo mysensors
