If the door switches act like normal reed switchen then it is correct that you can put one wire to ground and the other one on an input of the arduino.
Internally you can set the pullup resistor on the pin and check when the signal goes to low, to detect that the door is closed. If the door opens and the reed switch is open, you will get a high signal from the input pin.
But you can also connect one pin of the sensor to 5V and the check if the output pin of the sensor goes to high when the door is closed.

For the movement sensors you have to check the signals. There should be at least 3 pins for each sensor, power, ground and the signal itself.

Is there an overview about what was changed since the latest 1.x version?

Edit:
Sorry, did not see the link.

How are the leds connected to the arduino? Are the LEDs connected to ground or 5V?

Hello,

I want to switch my NRF24L01+ modules with RFM69 modules.

Which version of the RFM69 should I use? I have seen there are 3 different frequency versions and some versions with H, C and W?

I want to have a better range. I currently use the NRF24L01 modules on battery nodes to transmit humidy and temperature every 5 minutes. So no big data.

Regards
Stefan

Why not just connect the rx and tx pins and ground?

This is how I debug my battery based sensors and run them from the battery. You even dont need the rx pin if you don't want to send commands to the node.

It is not possible to mix the two type of radios, but you can install a second gateway with a RFM69 module, if the controller supports multiple gateways.

I did also receive all parts today and did solder an NRF24L01+PA+LNA WiFi Gateway. Everything runs fine from the beginning. Thanks.

If you upgrade from version 2.0 to 2.1 you can just compile the sketch without any modification.

Correct.

How do you achieve 3 years of runtime? How often do you wakeup the Atmega to measure the values and send them?

Do you have a link for the LED

But if you want to extend your system, you are more flexible with the MySensors solution in the future.

If you use arduino nanos you don't need any regulators. they have 3.3V for the NRF24L01+ and 5V for the relay.
You even don't need an ethernet shield if you connect the gateway via USB to your controller (Raspberry pi, ...)

This would be my shoping list:

For gateway you could use any arduino uno with or without a w5100 network or an esp8266 if you are just doing tests

ah, I wasn't aware of that. Are there any docs that demonstrate how to build a gateway using that ?

That might work out cheaper in the short term to see if this is a viable solution for what I want to do.

Hello,

Does anybody have an idea where I can buy a big amount of Arduino Nanos with FTDI chip?
I need around 100 Nanos or more.

I don't need genuine modules. I want them to be as cheap as possible. I can buy them from Aliexpress but the biggest number I could find is 5 items and the price is not really good.

Thanks.
Stefan

I'm right that there is no resistor between the LEDs and 5V or GND?
Is it not required?

I like the board and did already order some pcbs for testing.

I did not flash all my nodes with a static node ID and now all new nodes can join the network and are visible in FHEM.

#define MY_NODE_ID 10
#define MY_PARENT_NODE_ID 0

I think there is any problem with my WeMos gateway. I will analyze this more in detail, when I have some more time.

Thanks for your support. For me it seems that we have some general problems at the moment.

I will try the following things later:

#define MY_NODE_ID 10
#define MY_PARENT_NODE_ID 0
#define MY_PARENT_NODE_IS_STATIC

1. use dev version of 2.1.1

2. downgrade to 2.0.0 or less to check if the hardware is working without any problems

3. use a serial gateway or try to use my WeMos in serial mode
