Need a bid of help...

Rene046

Hi there i'm working on my first project.
got some code working fine, but would like to try to add an BMP180 or 280 into the sketch.
I.m working with the latest version of my sensors. 2.1
.
It would be nice to include a forecast but that a bid to hard for me at this moment.
so far i found a sample of a weather station, ith forecast, but im not shure if i need more sensors like a dht then.
.
Maybe some could give a sample or advice.

i forget to tell i have an bmp180 and a bme280 available

Rene046

What are the read command for an bme280
float temperature = bme.readTemperature();
float humidity = bme.readHumidity();
float pressure= bme.readPressure()
?

Rene046

this is what i got s far...
mysensor.readTempC() and bmp.readTemperature(); both not working.
now i got it accepted but my working sketch peaces give problems.

Take a look at nodemanager, it will simplify your life ☺️

Rene046

@gohan

Hi Gohan.

Im still learning .. nodemanager ????

Features

Manage all the aspects of a sleeping cycle by leveraging smart sleep
Allow configuring the sleep mode and the sleep duration remotely
Allow waking up a sleeping node remotely at the end of a sleeping cycle
Allow powering on each connected sensor only while the node is awake to save battery
Report battery level periodically and automatically
Calculate battery level without requiring an additional pin and the resistors
Report battery voltage through a built-in sensor
Can report battery level on demand
Allow rebooting the board remotely
Provide out-of-the-box sensors personalities and automatically execute their main task at each cycle

it looks intresting but i just started...

gohan

For beginners it's easier, it cuts down code quite a lot

Rene046

@gohan

Do you have a sample or could you help me starting with the sketch i already have ?

@gohan

i installed nodemanager i think ...lol

Rene046

This post is deleted!

gohan

maybe you set the something wrong in the sleep settings, but without seeing your code it's hard to give you an answer :)

Rene046

Found it i connected the BME280 in the BH1750 line after removing i worked again....
the sketch could not work without Seeing the BH1750.

my code is in my first post on top of this topic.

gohan

Yes, but I wanted to see if you made the modifications to run the nodemanager

Rene046

nope i dont even know where to start....

alowhum

Try this code:
https://github.com/flatsiedatsie/MySensorsArduinoExamples/blob/5c84100098352bab6db4b9c86e76db79842131ec/examples/WeatherStationSensor/WeatherStationSensor.ino
