Thanks for the question. The iTach, while a network based product, isn't connected to a central server which makes integrating with Alexa a huge obstacle to overcome.
It's an interesting space for sure, but it's not clear how the iTach in it's current form could be used with Alexa.
I think a solution would have to integrate the MobiLinc Remote app to bridge between Alexa and the iTach, but again, without a central Cloud service, there's a significant challenge here.
I've passed this along internally.
