Watching the MQTT logs, it seems the IKEA Tradfri remotes are interacting with the receiver constantly. This might be equivalent to pressing buttons non-stop, which might be why batteries are draining so quickly (see the sample log below). If this interaction could be limited, I believe the battery drainage could be limited.
