My 5 in 1 sensor stopped transmitting yesterday. I put new batteries in it. It still didn't transmit. This morning it started again (without any action on my part) The indoor display showed updated weather data, the AcuRite online dashboard showed a signal, but was not updating data. After an hour of trying to figure out what was going on, now everything seems to be working again. Any ideas of what was happening? The unit is only 3 months old.
