I have a series of temperature sensors that I am trying to integrate with my EmonCMS instance. I have a python script that reads the 433MHz data and then posts it to EmonCMS using the URL upload method.
Each sensor can have a house ID and sensor ID set. I might run out of unique sensor ID's for what I have in mind, so wanted to use both ID's to provide the unique node ID for emoncms.
Question: Is emoncms expecting only numbers within the unique node ID? Or can I use letters as well?
Re: url uploading and nodes
To answer my own question. The short answer is no.
Any Unique ID node containing a letter gets truncated. i.e. the URL that ends in:node=1S3&json={test:252.4}
gets truncated and added in emoncms as an input: node1_test
