Abstract: Some methods for detecting and avoiding radio interference in a wireless sensor network can include an access point device periodically transmitting a beacon message to a plurality of IoT enabled devices via a radio channel, upon receipt of the beacon message, an IoT enabled device attempting to decode the beacon message, the IoT enabled device measuring and storing a signal strength of a successfully decoded beacon message as signal strength data in a memory of the IoT enabled device, the IoT enabled device increasing a missed beacon counter stored in the memory of the IoT enabled device responsive to a beacon message that cannot be decoded, each of the plurality of IoT enabled devices periodically transmitting stored data to the access point device, and the access point device using the received data to identify an interference source, or an interference issue or a fading issue on the radio channel.

Abstract: Systems and methods for measuring and modifying an input voltage provided to a control panel are provided. Some systems can include measuring the input voltage provided by a power supply, determining whether the input voltage is within a range of acceptable input voltages, transmitting, to the power supply, a modulated signal on a direct current line between the power supply and the control panel instructing the power supply to modify the input voltage, and generating a notification when the input voltage is outside of the range of acceptable input voltages.
