Any ETA on support for RFM69 ? Need to extend my coverage

Is there any updated sketch to use with the Soil Moisture Sensor shown in the pictures?

Do you have an example sketch of connecting two PIRs to one Arduino? Would really need that in my setup.

@mfalkvidd Alright The thing is that I have my Raspberry Pi as a Gateway today near my server rack and would like to measure the temperatur. Maybe I just get a Nano to do the work for me. Just would have been great to use the Raspberry.

Can I attach one or more DallasTemp sensors on the Raspberry Pi gateway?

oh, I should have read this before I ordered the TCRT5000. I two seems to have hard time to get readings from my water meter.

I also have this small wheels.

I have a RPi and USB camera, so I could try that solution. But should have been nice with the TCRT5000.
Have anyone made any updates?

Great! Thanks for the help
Now I just need to figure out a good placement for it and get values to Domoticz.
But this helped me a lot to get started.

Should have said that I was trying to run it on a Node MCU 0.9. I can compile fine for Arduino Nano but not for Node MCU. Also I got another error now when I upgraded to 1.6.12.

Running 1.6.11, will try and update.

I use the following code, I have added the GW support for ESP board.

Anyone who can help?

Just installed MySensors on one of my Raspberry. Works really great! Picks up the other node I have over NRF without trouble. Next I will try and add some sensors directly on the Raspberry.
Big thanks for this!

I have an air refresher in the main bathroom, the problem with that one is that is spraying in constant intervals, so even if no one has been in the bathroom for a long time (during night for example).

Now when I have started with Arduino and MySensors I think it would be possible to hack this one, so I can trigger it via sensors or schedules.

Have anyone tried this before?

@mfalkvidd how did you come up with what kind of resistor I should use? Could be good to know in coming project. If you want to share, thanks

Thanks!
Yes I ordered a couple of days ago, waiting for them Need them for the temp. sensor as well.

65535 is the value I get when I print analogRead(LIGHT_SENSOR_ANALOG_PIN).
So, then I´m unable to use this light sensor on this NodeMCU? I better set it up on some other node.
Thanks for quick and informative replies

The Serial.printIn(lightLeve) is there already.

I´m using a LM393 Light sensor, if that helps.

Hi,
I´m using MySensors dev branch 2.0.1 as I heard this one should allow GW´s to have sensors on them and show for controllers.

I´m using a NodeMCU with the follow sketch, I can add the GW and it shows up, it presents me with nodes and there I can see S_LIGHT_LEVEL but there is no Name or Value to it. And I do not see any device.

Can anyone see some error in the code?

Cool, I downloaded it and replaced the old master brach.
Still get the same effect.
I paste my sketch here, all except the wifi part, that works. Tell me if I should include it here as well. But I feel its something in this below part that is failing on me

Uploaded this sktech to a NodeMcu yesterday, i can add it in domoticz. When i try to add a light sensor, it shows up as a light sensor node in domoticz under the Mysensors lan gateway. but it does not show any device. Anyone who have an idea?

I have just started with an Arduino Nano and connected both radio and a HC-SR50I PIR.
When I check the Serial monitor it spams me with
0;1;1;0;16;0

Is that common or is something wrong? Thanks for help.

Hi,

I would like to reach the watt usage. I would like to use SCT-013-030, but as it seems to have a 3.5" connector, how can I connect this to my arduino? I can only see project where one is using pulse power. But with this one I would not need to install a new energy meter where I would like to read the watt usage.

Any tips and ideas?

When do you think the install and build instructions will come up? Will this work with a B-model? (bought 2013)

@sundberg84 Yesterday I found you forum post at bygghus.se I was stuck at the phone for a long time reading it all! I´m very impressed and I will for sure order some of your board for the aurdino.

@stevebus Great!

I´m trying to find a Arduino Uno board, looks like the one in the mysensors hardware is out of stock. I searched on ebay and found this one, is it legit and the real thing?
http://www.ebay.com/itm/Arduino-Genuino-UNO-R3-Compatible-ATmega328P-ATmeg-a16U2-with-USB-cable-/252365926607?hash=item3ac22e70cf:g:DR8AAOSw1DtXHD1s

Thanks
Then I will test it out If it does not work I have to find other cables.
Yes I have seen that, really awesome

Hey,
how long cables can I use for the sensor that is connected to a arduino board?
I have seen this 20cm cables one can use. But I was thinking of having the sensors in locations like a couple of meters away from the arduino board. Like place the board in one area and pull cables to nearby rooms for temp readings etc.

As its low power I would assume I could do this. Any recommendations?
Could a regular network cable be used or is the twisted cables not good to use for this purpose?

Thanks

Patrik

Again, thanks for quick reply.
I´m starting to get a better understanding now of how its meant to be used

I have ordered some hardware now and will start to test.

Thanks once again.

Thanks for quick reply.

My idea is to have several nodes with "MySensors" connected to Domoticz. I currently have Domoticz running on my Synology NAS, so there is no option to attach gateway for that unit. Thats why I would need the gateways to have WIFI or ethernet connection. I can use ethernet in some places but else it would be wireless.

So the NRF24L01, or RFM69 modules is not WIFI network? WIFI is only included in the ESP8266?
But all system either if I use ESP8266 or Aurdino I need NRF24L01, or RFM69 for the system to function?

What I dont understand is what those modules are doing As I connect the sensors directly to the Aurdino or ESP8266. I never connect anything to the NRF module, right?

Sorry for all stupid questions Appreciate all help.

Br.

Hi,
I´m new here at MySensors and are very interested to start with sensors to hook them up to my Domoticz system.
My confusion comes with what hardware I should buy to accomplice my task.

I want to have wireless network on my controller, so that I can get Domoticz to talk to the controller over my existing wireless network
.
Will all three of the below options solve this or which one of the below? Will I need more than the hardware below?

• Arduino Nano and attach a NRF24L01+ 2.4GHz Wireless Transceiver
  or
• NodeMcu Lua ESP8266 CH340 WIFI Internet
  or
• NodeMcu Lua ESP8266 CH340 WIFI Internet and attach NRF24L01+ 2.4GHz Wireless Transceiver

Thanks
