Bond Bridge - Alexa - Extended delay to relay

Bond bridge - wireless fan remote emulation - When speaking to an Echo - Alexa states it cannot communicate with ‘Fan light’ (not responding). However the Bond bridge command will still successfully run after some patience (2-15 seconds after Alexa states the device isn’t responding). I don’t know where the break is… Alexa to Bond Server? Bond Server to Bond Bridge? etc. Ideas? I have not noticed this problem if I use the Bond app. Though it may not be related - Alexa similarly can sometimes not communicate via Bluetooth to Hue smart bulbs.

Via the Alexa app - I frequently see these types of messages
