Sensi smart thermostat temperature reading of 99F, dashes or humidity of 255%: meaning and exact next steps

temperature reading of 99F, dashes or humidity of 255% means Sensi says a temperature reading of 99F or more, only dashes for the room temperature, or a humidity reading of 255% likely means a problem with the internal sensor. This answer applies only to Sensi smart thermostats (Copeland), that show the message Call for Service, E5 or ES, or a Wi-Fi status that Sensi's support pages and manual describe. Sensi's support pages do not publish E1, E2 or E3 codes, so this page does not either.
