LaCrosse - sending weather information

[twinsen]

It is possible to emulate LaCrosse Weather station protocol using RFlink ?

I have a lot of sensors made with arduino Nano and DHT 22 that emulate the protocol and I want to migrate them to ESP8266 +MQTT and to continue to send informations on 433 MHz via RFlink

Code: Select all

20;17;LaCrosse;ID=0402;TEMP=011e;
20;18;LaCrosse;ID=0402;HUM=26;
20;19;LaCrosse;ID=0502;TEMP=0116;
20;1A;LaCrosse;ID=0502;HUM=29;
20;1B;LaCrosse;ID=0d02;TEMP=0114;
20;1C;LaCrosse;ID=0d02;HUM=55;

Hi,

I am not sure that I understand what you want to do.
You already have sensors that transmit (via 433mhz) to rflink..
now you want to use ESP? but still send via 433mhz?

To be more specific I want to send weather information using LaCrosse protocol on 443 mhz.

I have some device that receive data on LaCrosse protocol and I don't want to change them.

P.S. I discover RFlink last week and I build it. I was impressed by how well it works

Nice print
Add the NRF24L01 for MiLight

Obviously the Lacrosse protocol is supported by RFLink.
If you want to use something other than the USB connector, you could go for Ser2net using an ESP.

For me it's not clear
RFlink can only decode (receive )the LaCrosse protocol or it can decode+transmit ?
If it can transmit what is the sintax ?

Ahh.. i understand what you want to do.. But sorry, the answer is no.
RFlink is currently only able to receive the various sensor protocols.
It has transmit capabilities only for switches (wall sockets, lamp control etc.)
There was no need to implement transmitting all the dozens of sensor protocols as there would not be any device listening to the data anyway..
