Hi, I am using some ESP8266 devices with Arduino and MQTT client software. They are connected to senors, relays and other stuff all over the house. I have a dedicated wifi router(isolated from main home network) for my HA(home automation), connected to Linux openHAB server. Outside access to HA network is blocked, but HA network can access internet.
I was wondering how often a connected ESP8266 device will normally transmit data? Not referring to the transmits initiated by me(request sensor data, set relay..), but network related communication. Does a typical connected, idle WiFi device often transmit data? Maybe network broadcasts, keep alive messages or other? Is there a way to measure this? I do not want all these devices to be radiating RF signals all the time, but not sure what they are up to?
