Hello, first you are an amazing community. I'm new here and I have a case. I'm trying to check the temperature with a custom thermometer and I have the following points, channel, oid, IP, and port. I tried with UDP but without success. If anyone has a similar setup or has an idea of how to do it I will be glad.
Sorry for my English it's not that good.
Thanks in advance.
Welcome to the forum @svetlinsem.
Without some information on the thermometer and what protocol it supports it is difficult to help.
"OID?"
Is this an SNMP OID?
Hello,
We use one wire protocol with DS1820 .
Steps:
- Open socket
- Ask in hex (OID and Chanel)
- Recieve answer in hex.
So what is the question? What has the 1-wire protocol got to do with sockets?
Yes and how to implement in node red.
How to implement what in node-red? If you search for ds18b20 you will find there are a number of nodes that will access them. I use owserver with my 1-wire devices and then node-red-contrib-owfs to read them.
