LMClient Commands

These are commands which can be passed to the linkmeter daemon over the UNIX socket. All commands begin with "$LM", however $ symbol is optional when using the lmclient.lua script. If the script is called with no command, $LMSU is assumed.

• LMST,X,Y - Set command. Passes a /set?X=Y to the HeaterMeter. X and Y must not be URL encoded. Returns OK or ERR.
• LMSU - Request state update. Returns the last state update from the HeaterMeter, JSON-formatted. Includes UNIX timestamp and RF status when available.
• LMRF - Get RF status. Returns current RF node status information. Last seen UNIX timestamp, battery level, and signal level.
• LMD0 - Stop the serial monitor daemon, the actual linkmeterd portion that receives and records data.
• LMD1 - Start the serial monitor daemon. The daemon is will not start multiple instances if you call LMD1 multiple times.
