Anyone have patients using interfaceable blood pressure cuffs?

Is anyone using any of the medical devices listed in my.eClincalWorks like patient blood pressure cuffs or glucometers.  We want to buy a large amount of patient use blood pressure cuffs and looking at the medical devices listed for any information about being able to interface with eCW.  We’re also interested in purchasing glucometers for patients.  We’re looking at the Omron, Welch-Allyn and iHealth devices listed.  I’ve placed a ticket for a demo or info around interfacing, if and how, and so far, eCW hasn’t really answered any questions we have.  I’ve just spoken with a coordinator who tried to gather information for his team to talk with us. They also keep updating the ticket that they don’t understand our request and need more information.  Getting a little frustrated.  Just need a yes and how or a no, the devices do not interface.  Anyone using them or know if they do or do not interface?
Thanks!
