I currently have 3 nest learning thermostats and thermostat e . I recently added the c wire when I started getting the error e159. Before that my unit would work fine but occasionally would go offline for low battery. I decide to add the c wire to correct that however I get the e159 code which indicate low or no power. I took a voltmeter and it read 28 volt at the thermostat between the red and the common wire.

Hey Jmt359,
