By the end of the second year of operation, the bluetooth failed. How so, I do not understand. Everything is on the display as usual, the 'bluetooth' indicator is on, the temperature and humidity readings are taken and displayed on the screen, but the bluetooth does not work. I took out the battery for a long time to reset the settings, it does not help. By holding the button on the device and turning on the search for devices in the application - the device is not located, the application does not take readings. He worked all this time from the moment of purchase in tandem with the humidifier "Xiaomi Humidifier 2", he did not look for souls in him. The humidifier is configured in such a way that, taking readings from an external sensor, maintain the humidity in the room that I set in the range of 48-49 percent, and also change the fan speed depending on the degree of deviation from the required humidity and the time of day. Transmits readings via bluetooth to the humidifier once every 10 minutes, or more precisely, every 9 minutes 59 seconds. Before that, it worked properly, as they say, set the settings and forgot, once a year I replaced a dead power source. AAA batteries (Duracell) last for 360-375 days. The display is not so hot, but nothing. How is it possible for a blue tooth to break.? For a humidifier, you will have to buy a new one, and this will find application elsewhere. Addendum: after three, three and a half weeks, the bluetooth worked again as if nothing had happened. Everything is fine again.
