Have you followed the instructions in the readme?
I've tried all the nodes I've worked with so far, but it only shows me the sensor number.
On RPI3B+ no problems with same configuration of software.
Set a flow up as shown in the node's readme and show us what you get in the debug node.
My RPI's in the office, I'll be able to say tomorrow.
Thank you very much for your reply in such a short time.
Your node output contains an object with id and temperature. You need to add a change node to get the temperature. Set msg.payload to msg.payload.temperature, that should do the trick.
Hi, how i do this in function node?
This is my function code.
msg.payload = Number(msg.payload);
msg.payload = Number(msg.payload.toFixed(0));
msg.topic = "pool_temp"
return msg;
I cannot change msg.payload to msg.payload.temperature.
I want just to avoid change node. Sorry for bad english.
Thanks.
