I looked up the Alexa compatible OMRON units. Mine's not one. I have a BP5450. It is Bluetooth also, but is not capable of dealing with the monitor directly through Alexa. Although I think the app will connect to alexa, to get monthly stats and comparisons and such... but some of their higher-end Schmancy Monitors you can ask Alexa "What's my blood pressure"... I am assuming from reading, that the monitor needs to be in place and "on" to some degree for it to take your blood pressure using the Alexa app... which nearly makes the particular operation kind of moot, siince you should already be fairly aware that you have put your cuff on and turned on the machine... It'd be different if you could take your blood pressure with the Apple watch and/or a wearable type monitor... but only see BP monitors so far. Some things just don't really contriubute much to our "Smart lives"... this is one of those cases where very few will actually benefit from the app and Skill set ups... some will but it is kind of cumbersome overall.
