Party barn system was reading 57° on the Honeywell app. On site all thermostats were reading above 70° with party barn system set to auto 69-74 and reading current temp of 72° checked to make sure thermostat was connected to gateway and to remote sensor. Also checked to make sure thermostat was set to use remote sensor for room temp reading. Systems are programmed and operating properly. Issue is with slow internet connection preventing thermostats from updating the app or receiving commands from the app.
