My current home automation setup uses sensors with different technologies:

• MySensors (with node-red and serial gateway)
• zWave (with fhem)
• Homematic (with homegear)
• Netatmo
• Buderus (oil-fired heating, with fhem)
• Sonoff Dual (hacked, with MQTT)

I have adapters for all of them to/from MQTT. With node-red I have written an abstraction layer for all of them, which is heavily inspired by the mysensors API.

The most complex thing I have implemented, is a regulation for the floor heating. The regulation algorithm takes in account:

• open windows
• room temperature
• time
• lead temperature

Every room has it's own regulation. But it is dependent mostly on the room temperature sensor. I have written some fuzzy logic but if to many of them fail, it will get cold inside.

Tomorrow the old api of netatmo will not work anymore. It is the third time, I have written an adapter for my home automation setup. The new api doesn't really bring new functionality but I have to use it.

So I made a decision to replace all this netatmo stuff with MySensors (https://forum.mysensors.org/topic/4355/mh-z14a-co2-sensor/5).

It will be

• cheaper
• not dependent of the internet or the cloud
• up to me to decide, when or if I want to change the api
• fully open sourced
• not only IOT, bur IOYT

IOYT... what else?

Building a (xenon) flash to notify alarms. Flashes every 5 seconds if activated.

As I live near a nuclear power plant, I thought it would be a good idea to have a radioactivity sensor:

Components used:

  pinMode(DIGITAL_INPUT_SENSOR, INPUT);      // sets the geiger sensor digital pin as input

  if (currentMillis - previousMillis >= LOG_PERIOD) {

    cpm = counts * multiplier;

    counts = 0;
    previousMillis = currentMillis;

  }
}


void tube_impulse() {              //procedure for capturing events from Geiger Kit

  counts++;

}

I get cpm and in Node-Red I calculate microsievert/per hour:

Prototyping my netatmo replacement device. It has an led strip that can simulate a lighouse, a rainbow or a fireplace...
(If not used only for fun, it should warn you, if there is too much CO2 in the air.)

The sensor is really simple to use, when attached via serial-ttl (3.3V) and powered with 5 volt.

You get the values directly from the sensor and don't need to make calculations. Here is what I use:

/*
   The MySensors Arduino library handles the wireless radio link and protocol
   between your home built sensors/actuators and HA controller of choice.
   The sensors forms a self healing radio network with optional repeaters. Each
   repeater and gateway builds a routing tables in EEPROM which keeps track of the
   network topology allowing messages to be routed to nodes.

Testing a CCS811 CO2 sensor. It seems to use less power then the MH-Z14A I am using now. The CCS811 may even run on battery. I will compare measurements of these two sensors with a Netatmo sensor. The sensors have to burn in for two days bevore I start the comparison.

The CCS811 breakout board I use hast temp, hum and barometer sensors (and the CO2).

Here is my solution with support for generating node-ids, multiple controllers and a generic mapping to/from mqtt.

0_1473669025539_nodered-mys.txt

Not keen on soldering SMD, I designed my own PCB.

The PCB has a flexible design (use jumpers):

• use with battery
• use with 5 volt (and LE33 for NRF24L01+)
• use with voltage stabilazitaion to 3.3V (LE33) for ATMEGA328P and NRF24l01+

mysduino2.fzz

OSH Park Link

I am programming it with an ISP.

Use a 8 MHz setup: select Lilypad/328p in the Arduino IDE and first burn the bootloader.

Then I set fuses with mit usbtinyisp to not reset the eeprom with the upload of a sketch (no new node id)

./avrdude -C /Applications/Arduino.app/Contents/Java/hardware/tools/avr/etc/avrdude.conf -c usbtiny -p m328p -U hfuse:w:0xD2:m

an enable low voltage usage with battery:

./avrdude -C /Applications/Arduino.app/Contents/Java/hardware/tools/avr/etc/avrdude.conf -c usbtiny -p m328p -U efuse:w:0x07:m

Hmm, I have so many ideas and not much time.

• a push mysensors notification for amazon echo (alexa)
• maybe could be the same hardware as above: notify via voice about: window state, air quality, doorbell from mysensors...
• nice nextion display showing information about my home and the weather forecast
• doorbell sensor without additional power supply
• ac detection without additional power supply
• a mysensors serial mqtt controller for up to 3 gateways based on arduino due

Or should I first finish my heating circuit regulation which does work for more than two months now without any problem but isn't mysensorized...

Or should I invest in a blog explaining all the things I did and could help others? (i.e. how do I distinguish an arduino pro mini 16 MHz from a 8 MHz model or how do I connect different protocols ie zWave, mysensors, homematic, netatmo.....)

Or should I invest more time in my job?

What about photography? I really like to take pictures with old cameras on film but have done this last time 2 years ago...

Or should I paint my garage? It is really time to....

What about tidy up my garage and all my electronic items I purchased with that many ideas in my mind?

We don't talk about my family. I swear, they don't get to short.

Maybe a 3d printing project with my 8 year old daughter?

Sigh, life is to short...

@korttoma
It is working like a charme for me. Important is, to have 5V for voltage and 3.3 V on the logical level. Here is a graf, the green "Badezimmer" line is the mysensors sensor with MH-Z14A, the others are from netatmo. The mysensors sensor is in the bathroom and therefore it will have usually less CO2.

According to the schematic
https://www.arduino.cc/en/uploads/Main/Arduino-Pro-Mini-schematic.pdf
the ftdi header is attached to vcc and is not regulated. High level of cpu is then 5V.

According to the specs 2.7 up to 5.5 V should be ok @ 8 MHZ
http://www.atmel.com/Images/Atmel-42735-8-bit-AVR-Microcontroller-ATmega328-328P_Summary.pdf

I usually do it the other way round: use a 16Mhz pro mini @ 3.3 V to use RFM69 without level shifters. This is out of specification but working fine.

On my pi2 I have installed node-red and do all the 'wiring' of messages between different nodes there. Maybe this could be a solution for you too.

Here is my setup:

• MyMQTT Client Gateway, OpenHAB, HomeMatic and node-red all connected to mosquitto
• OpenHab configured to expose the internal bus to mosquitto
• All glued together with node-red: the OpenHab Items have no mqtt binding, all messages are exchanged via the OpenHab internal bus.
• Messages from any sensors are transformed in node-red to the destination (topic and payload)

The advantage of this setup is:

• OpenHab is only the GUI and doesn't need to know anything about the sensors
• I can exchange any sensor/actuator without any change in OpenHab. I can even change from a netatmo device to a mysensor device or vice versa.

I was thinking about replacing the MyMQTT Client Gateway with a Serial Gateway and node-red, but the gateway is stable since weeks.... never touch a running system. This would solve my biggest concern with the MyMQTT Client Gateway: it doesn't support encryption....

Thanks Norbert for the great work! Works very well with mosquitto.

I added support for gw.requestTime(...); by modifying MyMQTTClient.cpp after the lines handling I_CONFIG)

  else if (msg.type == I_TIME)
  {
    txBlink(1);
    if (!sendRoute(
          build(msg, GATEWAY_ADDRESS, msg.sender, 255, C_INTERNAL,
                I_TIME, 0).set(now())))
      errBlink(1);
  }

Now I have a timebase for low power (deep standby) sensors.

Next I will try to set the time on the gateway with a MQTT Message or NTP....

I found a label FTDI on one picture of the PCB.

I encourage you to read articles about arduino on breadboard and dive deeper or buy complete solutions like the sensebender micro.

It is a prototype and not finished yet.

I use a namespace for the different technologies for the MQTT Topic:
MyMQTT for MySensors
Netatmo for netatmo devices
homegear for Homematic
nodered for messages generated fom node-red
openHAB for the openHAB eventbus

Most of the wiring is defined in a hashtable. As this is more of a hack, I want to clean it up before I publish it.

Here an example for an RGB Led (MySensors) wired to openhab colorpicker and a homematic wall switch. Note: the wiring is bidirectional, I see the RGB Color in openHAB of the MySensors LED independent of the method I used to set it and openHAB doesn't know anything about Homematic or MySensors. I can evan add another UI (openHAB 2?) and other switches (MySensors Motion or Lux nodes) and everything would be in sync.

Features:

• Publish states to mqtt
• handle node-ids
• support multiple ethernet conrollers
• should be adoptable to serial controllers

Restrictions:

• read only, no values can be sent to nodes
• you will find others

Added support for:

• sketchinfo
• sketchversion
• time
• batterylevel
• dallas RTC and message to set time from outside

I love this one:
https://www.openhardware.io/view/268/RFM69HW-interstitial-board-for-Pro-Mini-Temp-Humidity-sensor

Please try again. Lesson learned: Don't answer posts on holiday with a tablet...

• Fixed node-id handling for new nodes.
• added write support (see "MQTT to MYS" convert for details)
• parameters can be set in 'MYS initialize'

Try to replace all "delay" with "wait", as the node is not responsible, when you are in a delay.

Try to add a watchdog:

• add a a wdt_enable(WDTO_8S) in setup
• add a wdt_reset() at the start of the loop

I had several problems with relays and power spikes when they are switched. I changed them all to SSRs and the problems are gone.

Good luck
Markus

For portable usage I have a https://pokitmeter.com/ which is really small and lightweight.

@thomme
This gateway has to remember all the sensors on the mysensors network. If you would add a new sensor, you would have to detach and reattach the Z-Uno from zWave network.

I don't think you have enough memory on the Z-Uno to do such a gateway and AFAIK the sensor types supported on the Z-Uno are very limited.

My solution for integrating different iot systems is mqtt with node-red. All systems have an adapter to a generic message structure and can be connected to all the others.

I use a mix of homegear,/homematic mysensors, netatmo, zWave, owntracks, Alexa, imperihome, Sonoff...

Stability is not sufficient. The connection gets lost from time to time.

Added a watchdog to add another connection, if no messages arrives.

Seems, that this is only interesting for me. If I get no feedback I will stop spaming this thread.

The SPI Pins are different on the MEGA2560 than on a 328-Arduino.

How is your wiring of the NRF24L01+?

AFAIK the piezo acts like a capacitor. If you don't use AC, you may have to discharge it with a parallel resistor or discharge it with a transistor.

You could find some useful information on eevblog, e.g. http://www.eevblog.com/forum/projects/how-to-connect-a-piezo-speaker-to-a-microcontroller/

toneAC:
https://bitbucket.org/teckel12/arduino-toneac/wiki/Home

Do you want to control the nodes from outside (e.g. via MQTT) or will the communication be only inside the mysensors network?

Implementing a controller on the gateway isn't that simple, as there is no plugin mechanism in the library, where you can extend for example the serial gateway.

For implementation details you can look at
https://github.com/mysensors/MySensorsSampleController/blob/master/NodeJsController.js

It may be easier to have a seperate arduino for the controller and attach a serial gateway. (I am working on a arduino due controller where you can attach up to 3 serial gateways.)

@mfalkvidd
Yes, this could be a solution.

When using gateways as 'nodes', I miss the automatic ID handling (I_ID_REQUEST...) and registration in the controller. I have to configure something in the controller for every new node.

This could maybe solved by a new hal/transport/ip.

As the ESP32 can act as AccesPoint and WifiClient at the same time, he could be a gateway offering his service to nodes via his AccessPoint on a separate WLAN.

Maybe this thread can help
https://forum.mysensors.org/topic/1245/building-an-ethernet-gateway-on-an-arduino-mega/4

@ben999 said in Piezzo siren/alarm:

But i don't quite get it :

driving the piezo speaker with up to 25V doesn't improve noise level at all
switching to differential drive @5V (so it's a 10V potential peak-to-peak) opens hell's doors wide open

You may try to use a 1kOhm resistor parallel to the piezo (as suggested on eevblog).

The 328P is working with
8 MHz in the range of +2.7 - +5.5 V

I do program all my arduinos with 5V.

Detach the NRF24L01+ and other 3.3V sensors or they may die while you attach 5V.

Use at your own risk.

I had a similar problem with the control of a heating mixer and three dallas sensors. I solved the problem with:

• replacement of the relays with solid state relays
• moved conttroller more in distance of the high voltage parts

I also added a watchdog and a reboot mechanism in case of sensor problems.

Maybe this sketch can give you an inspiration: (work in progress, MYS-Part not tested in depth)

Here is the start of the diary of my project,

Printing first draft of case:

• Hex lids are fine.
• back cover of temp hum sensor is missing... where is it
• The nextion display is not centered. (It is not symdetric in the pcb.) If I want it to be centered I may have to make the box quite a bit larger.

I am really impressed with the print quality of the wanhao i3 plus compare to the xyzprint davinci I had two years ago.

Nodes are quite cheap and why not use one node per function? On the other side, you can save many nodes, if you implement multiple functions in one node.

What do you prefer?

Why?

What are the cons and pros?

@Ticupolu
Are thes buttons switches or push buttons?

You call setRelayState only from the recieve functions. (Do I miss something?) This means, that relay changes must be initiated from outside and don't occur only from a button press.

Box has enough space for everything. If I hace time before the end of the contest, I will improve the design to be more friendly to hardware replacement without soldering.

Layer 2:

Take an old motion sensor:

Remove existing PCB:

Insert mysensors technology:

With more skills, it would look nicer:

#define INTERRUPT DIGITAL_INPUT_SENSOR-2 // Usually the interrupt = pin -2 (on uno/nano anyway)
#define CHILD_ID 1   // Id of the sensor child

boolean interrupted = false;
int batteryRound = 0;

#define BATTERY_ROUNDS 20


MySensor gw;
// Initialize motion message

Minimalistic PCB (self designed with fritzing):

The PCB has a flexible design (use jumpers):

• use with battery (used here)
• use with 5 volt (and LE33 for NRF24L01+)
• use with voltage stabilazitaion to 3.3V (LE33) for ATMEGA328P and NRF24l01+

What do you think about a sensor type geiger counter with cpm and microsievert? V_VAR1 for cpm ist not cool

My actual project is a doorbell sensor with additional temperature and humidity sensors. Tried different ways to detect the ring:

• hall sensor (failed)
• microphone (FFT, ongoing research)
• optocoupler to detect the 12V AC -> favorite solution

As I was heavy prototyping, I tried wire wrapping and it is fun:

@fotofieber said in What did you build today (Pictures) ?:

Testing a CCS811 CO2 sensor.

Unfortunately this is not a CO2 sensor. It's only a VOC sensor giving an estimated eCO2 value. It's useful to tell you if your room needs ventilation, but not much more. And as even the VOC part is not calibrated it's only good for relative measurement.

My tests will show, how far away I am with this sensor in my indoor usage scenario.

My Netatmo sensors claim to measure CO2 and are battery powered. They seem to calibrate themselves to the lowest level they measure in 24 hours. This behaviour seems to be similar with the CCS811. The Netatmo sensors seem quite close to my MH-Z14A.

In the datasheet for the CCS811 I have read, that you can't use them in your green house, because of its self calibration. Netatmo may have the same restriction too.

AFAIK the only similar sensors which are calibrated and give absolute values are SGP30 and BME680.

I have ordered a SGP30 some days ago and will test it too. The BME680 needs binary code linked which is a no go for me. (As a gift I would take it into my test setup. )

If you want to measure CO2 you need a CO2 sensor and it's going to consume a lot of power, at least too much for a battery powered sensor.

The problem with high power sensors is, that they produce heat, which can make your temperature measurements unusable.

As my CO2 sensors have a color led to show air quality, they are mains powered anyway.

[edit] there's also the MiCS-VZ-89TE TVOC sensor, they claim to have a curve of eCO2 not too far from NDIR sensor in their datasheet. But that datasheet is strangely poor in details, they didn't even put any electrical characteristics...
https://sgx.cdistore.com/datasheets/sgx/MiCS-VZ-89TE_V1.0.pdf

Thank you for the link. I have ordered one for my test setup. They are really expensive, about twice the price of the MH-Z14A, the SGP30 or the CCS811.

Other CO2 sensors I should use in my test setup?

I like the MH-Z14A and depending on my tests may stay with them.

EDIT: ordered a MHZ-19 for the tests

I use a similar design for a wireless door bell. To not be forced to push the button while the node is booting, I charge a large capacitor when a button is pressed.

@jaredwolff
I downloaded the binaries from the Bosch site and the source library from the github repo.

In the binaries archive is an arduino library with an example with the error, you found.... The github repo has no binaries and I couldn't get it up with the binary.

The binary distribution of essential code makes it more complicated than it could be...

The integration in platformio is not to complicated in my code. I only had to add (after investigating for some hours)

build_flags =   -Llib/BSEC/src/esp32/
                -lalgobsec

@jaredwolff
My experiments with VOC sensors were all not satisfactory.

The NDIR-sensors reported more or less the same as the netatmo devices and I will therefore stick with them. Apart from that, using the NDIR-sensors in arduino is much easier and you don't have to store baselines or link precompiled code.
