Hello,

I'm trying to get the battery level percentage reported but only get battery voltage. Here is my sketch:

I'm probably doing something wrong. Any help will be much appreciated.

Thanks

@bbastos said in BME280/BMP280 high comsumption when sleeping:

7uA during sleep

Sounds pretty good to me!

You calling it done then?

Yes, it`s pretty good! But I'd like to use nodemanager on my nodes, it's so much easier I'll open an issue on nodemanager's github.

Thank you so much for the help!

Thanks!

Either way, using mysensors library directly with @rvendrame tips I was able to get 7uA during sleep.

@Memphis007 said in BME280/BMP280 high comsumption when sleeping:

Hi,
Looks like you're using the 5v version of the bme280, there's an extra 3.3v regulator on this board, this could be the culprit.

I really didn't paid too much attention when buying. I've taken better pictures of bme280 and bmp280, would you mind help me identifying?

Is there any way to modify the 5v version to works with 3.3v?

@TRS-80 said in BME280/BMP280 high comsumption when sleeping:

I am still one of the newer people around here, so I could be off base, but my first thought was "how are you measuring that?"

You need to put the digital multimeter in series with your circuit +- like this:

Please don't mind the bad quality pictures.

@rvendrame said in BME280/BMP280 high comsumption when sleeping:

@bbastos , welcome to mySensors. Try to add these lines before the sleep():

digitalWrite( A4 , LOW ); 
digitalWrite( A5 , LOW ); 

Stills unclear why, but it worked for me at least.

Reference: https://forum.mysensors.org/post/99876

Thank you @rvendrame! I'll surely try, the only problem is that I don't have control over sleep function, it's encapsulated in nodemager. I'll try to find the best place to put the code you've sugested.

Hello,

First, I'd like to thank you all for the hard working building mysensors and nodemanager. This's an incredible and motivanting way of learn and build DIY iot devices even by beginners like me. So my big thank you!

About my problem, I'm getting 0.50mA when sleeping using BME280/BMP280, just arduino(pro mini) and radio gives me 5uA. I've tried to power the sensor from digital pins using PowerManager power(5,6), but i'm still getting 0.50mA when sleeping.

It seems like the i2c bus is not being disabled when enter on sleep mode.

Any help would be appreciated.

@ghiglie said in BME280 node not sleeping:

That's not a bad test bed!

I'm having some "headaches" still. The PIR isn't sending the V_TRIPPED 0 , so I know when there's moving but not when it stops - I can manage it via HomeAssistant anyway.

I'm afraid I'll not be helpful now. Have you tried to update nodemanager library? I'm using the development branch from github.

Thank you! Ohh that's pretty complex for my super noob skills

I'm on the same vibe, using mysensors to start learning about electronics and automation. My first node is still on breadboard, but alive even after desoldering led and volt. reg. :

@ghiglie said in BME280 node not sleeping:

So, new message to get up a notification with my full working sketch. I'm so satisfied!
Putting a BME280 in a garage is an overkill, but I couldn't get a decent measure from the DHTs I have. I added a PIR to it, just for a minor convenience.
With next node I'll explore OTA features - flash and configuration.

Nice! Do you mind sharing a picture of your node? I've just assembled my first battery node using arduino pro mini and somehow it's working
I'm a beginner in electronics and would like to compare, see if I did mess up something.

Hi @ghiglie I'm still beginning in all this, but I think you need to call nodeManager.setSleepMinutes(minutes) otherwise the node will still awake.
