I am having this particular switch to be recognized in "Mozilla WEBTHINGS".

IS there some issue with having a repeater node and sensors/switches etc attaches to it? .. it sends in the data as it should when I check with MYSController and I can switch it from there with sending "V_STATUS" messages. but no luck so far of getting the sensors appear in WEBTHINGS , every other sensor works fine.

I was so happy to have finaly a fonctionnal sketch for my esp8266 gateway whith the DHT22 that i post directly my code.
I hope that it will help some people.

Hi,
Trying to go deep on the API and come this this doubt: The second example (with button) the child seems to be declared as "S_LIGHT" and the receiving messages are "V_LIGHT", while the first example seems better suitable for a relay (child as "S_BINNARY" and requests as "V_STATUS").
I haven't found any "S_LIGHT" or "V_LIGHT" in the API, only "S_LIGHT_LEVEL" and "V_LIGHT_LEVEL". What is the most suitable type for a relay node with a local button?

[skywatch]

@joaoabs A realy usually has only 2 states, on and off. So I would use S-BINARY and V_STATUS every time.

A changeover realy also has 2 states so again I would go for binary and status.

Light_Level is more suited to getting light levels from a sensor or sending a light level to a dimmable light.

[TheoL]

Not sure if it ever has mentioned before, but the first example contains

// Enable and select radio type attached
#define MY_RADIO_RF24

Which results in a compile error

MySensors.h:287:4: error: #error No forward link or gateway feature activated. This means nowhere to send messages! Pretty pointless.
   #error No forward link or gateway feature activated. This means nowhere to send messages! Pretty pointless.

It should be:

// Enable and select radio type attached
#define MY_RADIO_NRF24

And then it compiles and works :)

[mfalkvidd]

@TheoL which version of MySensors are you using when compiling?

The change from NRF24 to RF24 was intentional.

[TheoL]

@mfalkvidd I'm in an older version I discovered. Ran across more small differences.

[skywatch]

@TheoL Sound like a good time to update to the latest version. it is the best yet and very stable.
