@mfalkvidd Good! I have now succeded in getting 2.2.0 Beta up and running with Ethernet GW

@Jokgi Mots probably they are not genuine (bought from Aliexpress) but these devices themselves have not caused me any issues before. It started when I upgraded to 2.1.1. Although, after a clean install with 2.2.0 Beta it started working again so I am 100% sure that it's not the modules

@gohan Yes, otherwise it fails already during build

@gohan I have tried a clean install both with Rapbian Stretch and Raspbian Jessie but the results are the same

@Yveaux The FAIL´s all occur with 2.1.1 and the OK is with 2.2.0 Beta. Same radio connections for both so the FAIL´s should not be connected to communication with the radio module. I have also tried 3 radios and 2 different ways of connecting them (Shield and Dupont cables) Even if 2.2.0 starts OK the problem is that it for the Ethernet GW it fails to connect

And for the Serial GW it gives the following error in Domoticz

2017-10-10 18:43:08.538 MySensors: retrying in 30 seconds...

None of them picks up sensor reports

@gohan Now I have tried compiling it with one line command but the GW still don't start with 2.1.1

./configure --my-transport=nrf24 --my-gateway=ethernet --my-port=5003

@Yveaux Thanks for the feedback but I am using a RPI Shield so the connections should be stable

@gohan Thanks, will try that as soon as I can

@mfalkvidd Sure, below are commands and debug logs for both 2.1.1 and 2.2.0 Beta

As you can see both of the Gateways fails with 2.1.1. I have seen other people having the exact same problem so that is why I thought it could be something with the libraries

Then the GW repeats the last 2 lines forever

Compiled it with IP 127.0.0.1 for the controller and port 5003

It does not pick up the sensors and values

If I compile it with the local IP of the controller I get the following errors

After that the last 2 lines repeats forever

I have submitted a bug report on this

Hello,

I would like to submit a bug report for these libraries in the use of NRF24L01+ radio

I have problems with NRF24L01+ on both 2.1.1 and 2.2.0 Beta

I have installed a fresh RPI with all new libraries and trying to make a RPI Serial GW

In 2.1.1 it doesn't start at all but in 2.2.0 it starts but in the log I constantly receive the following in the Domoticz log where I have added the GW

I2017-10-09 19:25:12.306 MySensors: Gateway Version: 2.2.0-beta
2017-10-09 19:25:12.306 Error: Serial Port closed!... Error: End of file
2017-10-09 19:25:13.306 MySensors: retrying in 30 seconds...

After a while I get the following in the console

mysgw: TSF:MSG:READ,0-0-0,s=0,c=3,t=2,pt=0,l=11,sg=0:Get Version
mysgw: !TSF:MSG:LEN,0!=18 

The above points at something wrong with the radio connection

I have tried 3 different radios but still no luck so I guess it has something to do with the libraries

I also have problems with NRF24L01+ on both 2.1.1 and 2.2.0 Beta

I have installed a fresh RPI with all new libraries and trying to make a RPI Serial GW

The above points at something wrong with the radio connection

I have tried 3 different radios but still no luck

So I guess it all boils down to that there is some problems with these libraries and the NRF24L01

Any guesses?

Nice work! Any chance you can post some code samples to interact with MySensors gateway?

@sundberg84 Thank you for your feedback! I used the design found here so the sensor is OK. I had also tried to use a pulldown resistor but it showed that I had used too low value. When I use 10k as you suggested it worked like a charm, thank you! What I dont understand is why I should need the pulldown resistor in the first place? Shouldn't it be possible to solve that in the software?

Hello, I have built a number of these sensor nodes and really like the generic design!
However I have run into trouble when trying to build a power meter with a photo sensor.
I am using the code from MySensors but also tried other sources but my problem is that the digital pin i am using (D3) dont drop enough for the sensor to treat it as digital 0 as it stays at 2.3 V with a 2 AA battery power attached

When trying the pulse sensor with external power it works perfect so it seems like D3 is floating which also is confirmed when I measure on D3 without the sensor attached. (approx 2.7V)
I have used this row in my sketch pinMode(DIGITAL_INPUT_SENSOR,INPUT_PULLUP);

Any clues what I can try?

The electronics work perfect in the TH version but it seems like the enclosure is too small for it to fit.
I needed to carve a bit both on the bottom and lid to be able to mount them together

Nice work! Can you please upload the STL file as well?

@Eawo Domoticz groups sensors after the order you present them in, see: https://forum.mysensors.org/topic/5132/ds18b20-ans-sht31-d-show-up-as-combined-sensors-on-domoticz/15

I send every 5 minutes and check the value before so that I only send if the value has changed

I have been running my sensor for nearly 2 months now and battery level has only decreased 1-2%

Make sure you use 1 MHz bootloader

@hek Thank you, you are absolutely correct!

I found a description on how to edit the SQLite table to remove old values

Now I think I am up and running

Yes, I am using Domoticz and have cleared the nodes & childs (Settings/Hardware/MySensorsGateway) from the tables but still it the deleted value is being reported back to the sensor at startup

@hek Thank you for the suggestion but I tried that with no luck

But I realized that you need to detach the interrupt when entering loop() and then attach it again in the end of the loop(). Then it seems like at least the receive() function is entered. However I still have troubles with the SLEEP mode and getting it to report kwh to the GW

Meanwhile I have been looking at This Example and it seems like its working better even if I have some conversion problems but I guess that it is due to an incorrect formula on how to calculate watts

One big problem though that you might know the solution to. How do I clear the gateway value that the sensor reads at startup (V_VAR1)?

I've been looking at This Link but I am not sure if that's the way to go?

@miljume said:

I have worked with this sensor for over a week now but still can't get it to work in sleep mode

So far I have noticed some strange things, please correct me if my assumptions are wrong

• It seems like request(CHILD_ID_POWER, V_VAR1); in setup() is not being run when in sleep mode
• When that function is not executed, the boolean pcReceived is not set to true
• When pcReceived is false the code never enters if (pcReceived && (SLEEP_MODE || sendTime)) where all the "magic" happens
• Pulse counter gets updated (i.e. interrupt occurs) but as the code never enters the if statement where everything is calculated and sent to the GW things dont work

And I still havent figured out how to clear the V_VAR1 in the gateway ...

Hello,

I have built a power meter that works just fine when I use sleep mode = false but that uses up the battery in no-time

As soon as I switch to true it stops sending values, I waited for one hour without any transfers and then I gave up

How is it supposed to work?

Another thing I can't figure out is how to clear the stored pulse count in the gateway, after the tryout is done I would like to start from scratch

Anyone that can help me with these two problems?

@flopp Thanks for the link but I still cant get anything in sleep mode

Now I have waited for over an hour with simulated blinks approx twice/second but so far the device havent reported one single time!

By the way, does anyone know how to reset the value stored in the GW?

After some testing the value get's quite high

@flopp Yes, that was my intention

But I wonder how often the sensor send data to the gateway in that mode i.e. how the mechanism works

I might not have waited long enough but it would be good to know what "long enough" is

Can someone please explain how the sleep mode works?

My sensor works like a charm when sleep mode is "false" but when changing to "true" i get nothing to the GW

Exactly the same setup, the only thing I changed is from "false" to "true"

Hello

I also have big problems with getting the node to send temp and hum values
It starts up and presents itself to the GW but then nothing happens

I have tested the SI721 module with a simple arduino code and then it reads and prints both values just fine

My code is below, in practice its a version of Sensebender Micro code. I have changed the force transmit value to 1
Exactly as @clempat I have tried both 1MHz optiboot and 8MHz internal oscillator without any success

*******************************
*
* REVISION HISTORY
* Version 1.0 - Thomas Bowman MC8rch
*
* DESCRIPTION
* Default sensor sketch for Sensebender Micro module
* Act as a temperature / humidity sensor by default.
*
* If A0 is held low while powering on, it will enter testmode, which verifies all on-board peripherals
*
* Battery voltage is as battery percentage (Internal message), and optionally as a sensor value (See defines below)
*
*
* Version 1.3 - Thomas Bowman MC8rch
* Improved transmission logic, eliminating spurious transmissions (when temperatuere / humidity fluctuates 1 up and down between measurements)
* Added OTA boot mode, need to hold A1 low while applying power. (uses slightly more power as it's waiting for bootloader messages)
*
* Version 1.4 - Thomas Bowman MC8rch
*
* Corrected division in the code deciding whether to transmit or not, that resulted in generating an integer. Now it's generating floats as expected.
* Simplified detection for OTA bootloader, now detecting if MY_OTA_FIRMWARE_FEATURE is defined. If this is defined sensebender automaticly waits 300mS after each transmission
* Moved Battery status messages, so they are transmitted together with normal sensor updates (but only every 60th minute)

Thank's!

I downloaded the development version of the library and installed, seems to work fine and compiles without errors (except from the MY_LEDS_BLINKING_FEATURE which I removed)

I only used the code that is written here: https://www.mysensors.org/build/ethernet_gateway. Have not changed anything at all

Could it be that I have a mixup between old and new library files from Mysensors (i.e. old mysensors.h)?

I didn't find a description on how to upgrade the library files for Mysensors so it might be that I did someting wrong

Hello

I have used the version on the build page for ethernet gateway and used the last version of RF24 library for maniacbug together with Mysensors 2.0 library

But I still get a bunch of these errors when compiling

Hello,

I installed the server on my RPI with Raspbian today and followed the steps in your guide

However when I try and access my server through http://<local ip>:8080 I only get "Website cannot be reached" and "ERR_CONNECTION_REFUSED"

Any hints?

Regards,
Mikael

@zampedro Sounds perfect, is there any chance this change can be merged into the source of Domoticz?

@zampedro I have exactly the same problem

Could you please tell me more of how you modified Domoticz source?

This bug is really annoying!

Regards,
Mikael

Thanks for a quick reply!

I tested this code tonight but have the same problem, two devices popup in Domoticz but the second one (with DS18B20) also reports humidity which i guess is received from DHT22

Not a very big problem if you know the setup but you could easily think that the humidity comes from the same measurement point as the DS18B20 which it dont

Hi,

I have created a sensor with both a DHT22 and a DS18B20 which will be located in my bathroom with the main unit with the DHT22 inside the bathroom and the DS18B20 (cable mounted) will be located in my sauna

This seems to work fine but when I view the sensor in Domoticz it shows two devices with temp and humidity for both of them! I only want the DHT22 device to be temp & humidity and the other device to be temp only

Is there a way to do this in the code?

I have used the example sketches for Humidity and Temperature and put them together into one sketch so that I have one sensor with three child devices

Anyone that could give me a hint?

Regards,
Mikael
