Looking for Thermostat option for Blind/VI users

Hello everyone.  We are looking for options from Demo/Loan centers to control Thermostats for folks with a visual disability.  Recently have had requests for manual adjusted rather than operation by phone or tablet.  We are looking for any options and feedback for either manual or electronic management.  Please give a shout if you have any that have been successful or in your toolbox.  Thank you so much!
