First I assume that you are talking about our on premise solution vs our Cloud hosted solution. Our on premise solution runs on Niagara. You either need a JACE, Niagara Supervisor or a Dell Gateway running Niagara in order to run Tenanteye on site. Then Niagara can integrate into your BACnet network directly or possibly via the BAS system as long as the protocol is compatible. You can download Tenanteye and it will run 2 hours at a time in demo mode to test this. We will be uploading the N4 version soon.
