Very cool project

@sundberg84 ooh that is not very long ..i hoped for a couple of months....but then I should consider this board as depreciated and build a new one and use this for development. Thanks for your reaction.

@sundberg84 yes i thought so, but i want to make sure. I have some Rev 10 boards and i was working on a node for my bathroom with a DHT11 sensor. I had some problems with it, therefore watching your video. But it looks like the step up booster was not working correctly. Unfortunately removing the booster i damaged the board because with a new booster the arduino won't get power any more. So this board only works without the booster (and reg jumper connected). Any idea how long this setup (with removed led on arduino) will last on batteries?

Hello @sundberg84. I watched your video 9+ 'MySensors Battery Node 2xAA - EasyPCB (Nrf24l01+)and Temp Sensor' . I have two questions about this video:

• I noticed you connected the tempsensor to the extra prototype part of the board, but i could not see in the video how you connected signal pin of the sensor to the arduino.
• you added a resistor to D5 Temp/Hum, but you did not add the sensor to the mysX2.4 part of the board. Why is that?

@mfalkvidd I never thought of that, but that could indeed be the case. In domoticz there is no data timeout configured. So still cant explain why domoticz is reconnecting.

@electrik i am not using MQTT with the gateway. I use still the 2.3.0 board.

Recently I updated my MySensors gateway (ESP8266) to version 2.2.0. Perhaps i didn't noticed it while i used the older version, but because i updated it I noticed that the gateway is rebooting regularly. Still my sensors are working fine. I am using Domoticz as controler (latest beta)

Any ideas to narrow down this issue? I already tried several different radio's, but i don't have spare ESP8266 boards lying around

@sundberg84 I just finished my first battery sensor node based on the Easy PCB Rev 9. I have two questions i hope you can help me with:

The first is about the battery measurement. Because i didn't have a 0.1 uf lying around i used an 0.2 uf capacitor. I am using the following script to measure the battery.

//=========================
// BATTERY VOLTAGE DIVIDER SETUP
// 1M, 470K divider across battery and using internal ADC ref of 1.1V
// Sense point is bypassed with 0.1 uF cap to reduce noise at that point
// ((1e6+470e3)/470e3)*1.1 = Vmax = 3.44 Volts
// 3.44/1023 = Volts per bit = 0.003363075
#define VBAT_PER_BITS 0.003363075  
#define VMIN 1.9                                  //  Vmin (radio Min Volt)=1.9V (564v)
#define VMAX 3.0                                  //  Vmax = (2xAA bat)=3.0V (892v)
int batteryPcnt = 0;                              // Calc value for battery %
int batLoop = 0;                                  // Loop to help calc average
int batArray[3];                                  // Array to store value for average calc.
int BATTERY_SENSE_PIN = A0;                       // select the input pin for the battery sense point
//=========================   


   // Calculate the battery in %
   float Vbat  = sensorValue * VBAT_PER_BITS;
   int batteryPcnt = static_cast<int>(((Vbat-VMIN)/(VMAX-VMIN))*100.);
   Serial.print("Battery percent: "); Serial.print(batteryPcnt); Serial.println(" %");  

Do i need to change anything in the formula? Because i getting reading around the 130%

Requesting temperature...DONE
Temperatuur : 26.62 Degrees C
11935 TSF:MSG:SEND,25-25-0-0,s=5,c=1,t=0,pt=7,l=5,sg=0,ft=0,st=OK:26.6

12945 MCO:SLP:MS=900000,SMS=0,I1=0,M1=1,I2=254,M2=1
12955 TSF:TDI:TSL

If i use the following method:

//----
   // 1M, 470K divider across battery and using internal ADC ref of 1.1V
   // Sense point is bypassed with 0.1 uF cap to reduce noise at that point
   // ((1e6+470e3)/470e3)*1.1 = Vmax = 3.44 Volts
   // 3.44/1023 = Volts per bit = 0.003363075
   float batteryV  = sensorValue * 0.003363075;
   int batteryPcntNEW = sensorValue / 10;

   Serial.print("Battery percent: ");
   Serial.print(batteryPcntNEW);
   Serial.println(" %");
//----

I am getting: (this is expected, because batteries are new)

Battery percent: 99 %
Sleep...
12945 MCO:SLP:MS=900000,SMS=0,I1=0,M1=1,I2=254,M2=1
12955 TSF:TDI:TSL

My second question is about casing: any tips on which case to use which fit your board and a battery pack? and is as small as possible? Do you perhaps have links of your favourite (Chinese) sellers?

@mfalkvidd Yes...it was indeed that simple. It works!! So thanks.

@mfalkvidd

Is it so simple?

You only have to add : #define MY_RF24_CHANNEL 86 (before the MySensors.h) in both the sensor sketch as the gateway sketch?

I have a couple of sensor nodes in my house on the ground floor. Now i would like to expand the network in my house so i am trying to get my first sensors up an running on the first floor, but with no luck. It seems that the radio (NRF24) cant get trough my concrete floor (the floor is solid concrete and around 40 cm thick with a lot of iron for reinforcement). I don't have problems with walls, not even when signal has to travel to multiple rooms before reaching the gateway.

My first thought were "ooh lets build another ethernet/Esp8266 gateway and place this one on the first floor". But after i build this and trying to get this up and running i read that you can only have one gateway

I already tried to extend the antenna of the radio, but with no luck. I don't have a power outlet near my stairs, for placing a repeater node. (and a long cable is not WAF proof)

So i was wondering anyone have a tip, for solving this problem. Thanks in advance!

@ben999 said in Geeetech Voice Recognition Module:

@dbemowsk Echo's family members only speak english and german so far...

That's my problem also...just English and German

I was looking for new projects, so i was looking for new cool sensors and found the voice recognition module of Geeetech. Because of the price of the sensor, I was wondering anyone already played with this module and integrated it successfully in a home automation system? For me some basic commands would do for example Lamp on, lamp off, Dim lights. I know there are some nice products on the market as Google home, Amazon Echo but as long as you only can buy a US version i wont buy it.

I already found a page with setting up the sensor: http://www.instructables.com/id/How-to-use-a-Serial-Voice-Recognition-Module-Ardui/

So let me know your thought on this one.

Finally i got some time this weekend to try out all of you tips. So thanks for those tips. Indeed the problem was solved when i moved the PIR away from the rest. But what i also noticed is that the PIR also have false positives (much less when it was near to radio, but still there where false positives) when it is close to the Arduino board and away from the radio. Therefore i decided to alter the setup and not to make the sensor a battery powered sensor, but use some ethernet cable to connect the sensors to the mainboard with the arduino and the radio. The cable is long enough to reach a wall outlet, so i can run the arduino and radio on normal power.

Because i had now all the space in the sensor module i added a DHT sensor. Now some new challenges arise. The sensor is working fine, but when the PIR is going off, it loops the sketch a lot of times (exactly 50 times) before it sleeps again. Perhaps someone can give me a hint which is causing this. My programming skills are not that good, so I have combined some different sample sketches. I am using currently the following sketch:

/**
 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.

@NeverDie @mfalkvidd I am also curious how you have done that. I picture would be nice!

After building my first combined sensor (not battery powered) i got enthusiastic about the MySensors project. This project as you can see was based on Arduino Nano and is working like a charm

So i wanted to add more off these combined sensor nodes to my smart house. This time i wanted to try a battery powered sensor based on Pro Mini (5v version) and built the following sensor:

Both project use the same PIR & BH1750 sensor and are running the same sketch (the second without the temperature sensor), but the second project (even if project is not powered by the battery) gives a lot of (and i mean a lot of) false positives.

I already checked the following things:

• tested the PIR also on breadboard with a Nano and there it is working fine

• the project with only the lux sensor is working fine (only removed the PIR in the sketch)

Can anyone confirm if i can rule out the difference between the boards i used (Nano and Pro mini)? Or perhaps does anyone can point me in the right direction how i can solve this?

@petewill Thanks for pointing me in the right direction. I am not a programmer but i managed to get this working with your sketch and the example sketch of the relay

Thanks for this great project/hack.

I built this project and it is working great, but i have a question about this. My controller is Domoticz and in Domoticz i have the two switches (DOORBELL_CHILD_ID, SWITCH_CHILD_ID). I though with this project i could also use the ringer of my doorbell as a sort of alarm in other combinations, but if a use the doorbell-switch in Domoticz the doorbell won't ring. But if i use the normal doorbell at my front door, it will ring.

Is there something wrong in my sketch or am i missing something else?

Thanks in advance for your help!

@mfalkvidd Thank you.....if forgot to upload the gateway software. I thought flashing the NodeMCU was enough. And of-coarse i had to update in the gateway software also the router information. That was the step i forgot

This is what the log says: (i rebooted to show you a clear log, otherwise only the uptime messages are shown)

I changed to new router from my internet provider (Ziggo). After adding all my fixed IP-adresses i have problems with mySensors gateway. It will not connect to Domoticz. I am now lost i tried a lot of things...but i don't understand why it is not connecting.

My setup is:

• Domoticz v3.8394 on RPI
• Mysensor node : ESP Easy NodeMCU (uploaded with https://www.letscontrolit.com/wiki/index.php/Tutorial_ESPEasy_Firmware_Upload)

My log is saying:

2017-09-15 23:21:27.287 New sensors allowed for 5 minutes...

From pi RPI i can ping the mysensor IP

I can connect with browser to mysensor node:

The following things i checked:

• all components are on the same IP-range

• in the settings page i set the 'local notwork'

• I built a new node but this new node gives the same problem.

• ect.

Anyone have a clue? Thanks in advance.

@gohan i am also affraid of a faulty module.....i am already waiting for new one to arrrive. i ordered now a ESP8266 version..hopefully more luck with that one.

@stevebus Yes the MAC address is also defined and i tried already different MAC address, so i know for sure it cant be a duplicate MAC address

@jkandasa I already tried to lock an IP address on the router, but that does not change anything

I am also trying to build the ethernet gateway. I already have built a sensor (humidity and temp sensor) which is working and tested it with the serial gateway. For the gateway I am using a ardruino nano and a W5100 Ethernet module. (arduino 1.8.2 and board 1.6.11)

The trouble i am having is getting a valid IP-number. In my scetch (it is the default scetch from the mysensors page for the gateway) i defined the following IP

#define MY_IP_ADDRESS 192,168,1,108   // If this is disabled, DHCP is used to retrieve address

When i start my scetch, i am see the following information in the serial monitor:

0;255;3;0;9;MCO:BGN:INIT GW,CP=RNNGA--,VER=2.1.1
0;255;3;0;9;TSM:INIT

as you can see the IP address is not correct, but it is receiving information from my temp/humidity sensor. Each time i reset the arduino i am getting a different value. Sometimes a part of my IP-address and sometimes just zeroes. In the page of my router with connected devices, i see sometimes new device with strange IP and part of de MAC-address.

does anyone have an idea?
