I need help!!!
I have e mcp23017 Matrix espander i/o in esp nodemecu board, the mcp receive state sensor from my system wired alarm(pir, sismic etc) ; this signal received i want send to my domoticz controller, is the sensor custom the solution? Can i present 16 input sensors from my node to my controller?
Tanks

user2684

@mar-conte if using NodeManager, this is still not possible since mcp23017 is not supported by NodeManager yet. Thanks!

@user2684
For example using text send if i receive state?

Hi, for anybody interested in giving the upcoming NodeManager v1.7 a try or share a feedback, please have a look at https://forum.mysensors.org/topic/9085/nodemanager-v1-7-beta-feedback-needed. Thanks!

user2684

Hi, the new version of NodeManager (v1.7) is now available! For those interested in having a look at the new features, supported sensors and capabilities, I've opened a dedicated thread on the forum here https://forum.mysensors.org/topic/9165/nodemanager-v1-7-now-available
Thanks

@user2684 this project is awesome! Thank you for your work and efforts. Just one question: what exactly is needed for "built-in battery reporting" hardware-wise? is it really "built-in" or do i need additional wiring and resistors for battery reporting? (I'll want to power up my 3.3V Arduino Pro mini with 2 AA cells)

gohan

since you are using 2AA batteries it can report voltage directly, in case you had any voltage regulator or booster it would require external resistors

Thank you very much. BTW: Is it possible to use Nodemanager with two, three or even four door sensors on a single ESP8266 (as Gateway without NRF radio)? Any help very appreciated!

user2684

@grau the current door sensor implementation (SensorDoor class) leverages attachInterrupt(); not sure how many interrupt pins are there on a ESP8266 but if there are enough it should work

@user2684 Hello all of You,
this topic is quite old, but hopefully someone is reading this.
I could not figure out, what to do if the NRF24 is wired to different pins.
I have a board with nrf24 on board, but this are connected like:
// Enable and select radio type attached
#define MY_RADIO_NRF24
#define MY_RF24_CE_PIN 7
#define MY_RF24_CS_PIN 10
#define MY_SOFT_SPI_SCK_PIN 11
#define MY_SOFT_SPI_MOSI_PIN 12
#define MY_SOFT_SPI_MISO_PIN 13
How can this be inplemented in the nodemanager?

user2684

@rpunkt just use those directives in your sketch, no differences with NodeManager, those will be seen by the MySensors library and applied. Thanks

RPunkt

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

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

@rpunkt my recommendation would be to create a custom sensor in NodeManager which is implementing the logic you like. Feel free to copy from https://github.com/mysensors/NodeManager/blob/master/sensors/SensorVL53L0X.h and create your own or make your own class by inheriting directly from SensorVL53L0X.

@user2684 Seems to be to difficult for a rookie :sob:
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 @user2684 et al,

I'm trying to use this library on an ESP32 board. I'm trying this sketch out (https://raw.githubusercontent.com/mysensors/NodeManager/master/examples/AnalogLightAndTemperatureSensor/AnalogLightAndTemperatureSensor.ino)

My problem is that if I just try to use the 1.8 version of NodeManager it will use as a dependency a version of MySensors which do not work with ESP32 and I get a known error regarding re-definition of app_main. Because of that I need to use the development version of MySensors but it seems not compatible with NodeManager 1.8 as I get the following error:

I have also tried using the development version of NodeManager with the development version of MySensors although I get the same result.
I'm stuck and I would really appreciate any input.

Thanks in advance!

@justfra thanks for reporting this issue, I believe there is some sort of library conflicts which is arising across MySensors/Nodemanager versions...something which has to be investigated carefully, I'll track this bug with https://github.com/mysensors/NodeManager/issues/491

ghiglie

Oh, I hate saying I've noticed this great piece of software just now! :( It would have saved me countless hours of software tinkering, giving more eyecare for better soldering...!

user2684

@justfra realizing only now the issue you reported was not ESP32 related but due to a compatibility issues between MySensors v2.3.2 and NodeManager just fixed in the development version with https://github.com/mysensors/NodeManager/pull/508. Either try the latest development version of NodeManager or use MySensors v2.3.1. Thanks
