SIM800L power saving question

Hi, I have one of these sim800L modules. My question is…im trying to get my project to save some battery power by putting my nodeMCU to sleep, but the sim800L still have a flashing red light. Any idea to disable the light? The module gets power from the nodeMCU


The NETLIGHT will always blink every 3 seconds when connected to network even if its in sleep mode. The current is negligible. You can check in AT commands guide, i think there is a command to disable the netlight.
