@user2684 Thanks for the advice. Now I got it running.

@zboblamont My question is related to:

This should be an easy way to get sensors running. It should be nice, if You have a battery- powered node as well.
But for me it is not clear what to to, if You want some extra information to be transmitted.
So I thought, that would be as easy as setting up a node.

Only playing a little with:
"NODEMANAGER_HOOKING OFF allow custom code to be hooked in the out of the box sensors"

As far as I understand, Your way is the conventional approach.
That will work for sure, but than power saving is an issue.
I want that stuff be powered by solar or battery. So it should be very power efficient. That is the reason to try the NodeManager.

@user2684 Thanks a lot

@user2684
Hello, it is me again. Going the next steps.
Now I want to operate another sensor (SensorVL53L0X).
this sensor should transmit the distance and the battery voltage every hour. in between it should sleep.
The normal reporting interval of the battery is once every hour
I set setReportIntervalHours(1); to report the sensor value.
But how do I set the node to sleep in between?
setSleepOrWait(True); and sleepBetweenSend(); ?
or
setSleepOrWait(True); and setSleepMinutes(60); ?
And is the NodeManager so clever that all the transmits are at the same time,
meaning once every hour the sensor value and the battery voltage is transmitted.

@user2684 Thanks for the advice. Now I got it running.

Question about PowerManger:
I am a bit confused or I can't find the right information.
I have an Ultrasonic sensor (SensorHCSR04) that needs to be only powered in case of measuring, due to power consumption.
An the sensor needs to be switched on a time before the actual measuring starts.
So my first approach was to switch the
#define NODEMANAGER_POWER_MANAGER ON
Then I set

 nodeManager.setPowerPins(5,6,500)

Where I a a bit surprised, why I need two pins (for vcc and ground)?
At what logic level are the when the PowerManager switches to ON or OFF?
Do I need to connect both pins, or is the vcc- connection enough?
Anyway, somehow it did not work with me. It seemed, that the pins are not switched in that way, that pin5 goes to ground and pin 6 goes to 3,3 volt.
So I found that thing :

// power all the nodes through dedicated pins
nodeManager.setPowerManager(power);

But here is no timing possible.
Am I missing something?

@user2684 Seems to be to difficult for a rookie
On the conventional MySensors library it is possible with my abilities, but then the power management is a issue.
For me the NodeManager was the choice, because it saves so much battery energy.
Other way of solution:
A friend of mine, convinced me off doing all the calculations in the home- automation (in my case FHEM).
Now I only use the node transmitting the distance and calculating the "volume of water" and "percentage of water" as a "user reading".

Hello all of You,
if have a flight time sensor VL53L0X, that is running so far.
It should measure the water level in a rain tank.
But now i want to customize my sensornode in that way, that two other values will be transmitted.
It should be
V_level, that represents the percentage of my water tank
and
V_volume, that represents the available volume of water
V_level and V_volume could be calculated from the sensor value of the distance sensor (VL53L0X).
But somehow I could not manage to to get this running. I don't know where to insert what.
Cant someone point me to the right direction, help appreciated

@zboblamont Maybe I expressed myself not clearly. I want to make the calculations on the node (the arduino). The distance, that the sensor is measuring should be transmitted, the fill rate in percent should be transmitted as well and the "liter available" should be transmitted also.

MyMessage msgdistance(CHILD_ID_DISTANCE, V_DISTANCE); //distance from sensor to watersurface
MyMessage msgVolume(CHILD_ID_WATER, V_LEVEL); //water availble in liters
MyMessage msgPercent(CHILD_ID_PERCENT, V_LEVEL); // water percentsge available

Sorry, but I am just learning

@user2684 Thanks a lot. I should have tried this, before to post a question, but sometimes the brain is sticky.

Hi, I am just making my first steps with the NodeManager. To get a simple sensor running is very easy, but how do I get custom code on the sketch?
I have a distance sensor, that is monitoring the water level in a water tank.
But I want the node also to present the level in percent and volume in liter. The should be done by hookon- code and be presented as well.
Can someone give me some hints or give an example?
