A system for collecting building environmental sensor data includes a first data collection device having a first transceiver that is configured to receive data from proximate building environmental sensors and a second transceiver that is configured to communicate with an external service. The device will, upon detecting that the first transceiver is within a receiving range of a first building environmental sensor, communicatively connect with the first building environmental sensor to receive a data stream that comprises sensor data captured by the first building environmental sensor. The device will continue to receive the data stream until the first transceiver either receives all of the sensor data or moves out of the receiving range. The device will repeat this process for additional building environmental sensors. The device will use its second transceiver to transfer the sensor data to the external service.

A heating control method, applicable to a heating element of an electronic vaporization device, includes: controlling the heating element to perform heating to a first preset temperature within a first time period; controlling the heating element to keep working under the first preset temperature within a second time period; and controlling the heating element to decrease from the first preset temperature to a second preset temperature within a third time period. The heating element is controlled to perform heating at at least two different powers within the first time period and/or the second time period.

An apparatus for cooling a food item may include a base and a top, the top and the base defining an interior chamber configured to receive the food item, and a fan coupled to the top and configurable in an operating mode and an off mode, wherein the fan moves air within the interior chamber when in the operating mode. The apparatus may include a temperature sensor to measure a temperature of the food item within the interior chamber and provide a temperature signal representative of that temperature, at least one user input allowing a user to select a cooling parameter, and a control unit adapted to receive the temperature signal and the cooling parameter, wherein the control unit is configured to switch the fan from the operating mode to the off mode when the cooling parameter has been met.

The present disclosure relates to a method, device and system for air conditioning units. The method includes: acquiring information of air conditioning units; determining air conditioning units that need to be networked according to the acquired information, wherein the air conditioning units that need to be networked include a first air conditioning unit and a second air conditioning unit; sending the information of the second air conditioning unit to the first air conditioning unit, and sending the information of the first air conditioning unit to the second air conditioning unit, wherein the information of the second air conditioning unit is used for the first air conditioning unit to be networked with the second air conditioning unit, and the information of the first air conditioning unit is used for the second air conditioning unit to be networked with the first air conditioning unit.

Methods, systems, and computer program products for interfacing with thermostats for heating, ventilation and air-conditioning (HVAC) systems are provided. Aspects include receiving, by a user device, job data comprising a location of a job. The credentialing data is transmitted, by the user device to a server, wherein the credentialing data comprises the location of the job. Also, responsive to transmitting credentialing data, thermostat setup data comprising HVAC system information is received by the user device. The user device connects to a thermostat and transmits the HVAC system information.

A method for controlling an environment within a sterilizer device is disclosed. The method includes equipping an interior space of the sterilizer device with an auxiliary device having a temperature sensor, a humidity sensor, a heating element, monitoring temperature within the sterilizer device, receiving, by the sterilization device, information associated with an initiation of a sterilization cycle of the sterilizer device; monitor duration of the sterilization cycle, receiving, by the sterilization device, information associated with an end of a sterilization cycle of the sterilizer device, determining whether a current humidity measurement is above a predefined threshold, and controlling the heating element to an ON operating state when the current humidity measurement is above the predefined threshold.

The disclosed technology includes a system and method of preventing short cycling in a water heater. The system can include a burner, a temperature sensor, and a controller. The controller can be configured to perform several steps to determine whether to turn on a burner and whether to increment a temperature offset value based on the amount of time that has elapsed since the last time the burner was on.

A stepless temperature control method for an air fryer includes the steps of detecting and analyzing an air temperature in an air frying chamber of the air fryer in a real-time manner to obtain a temperature change in the air frying chamber, modulating a parameter of a stepless control signal according to a preset target temperature and the temperature change, and, in response to the modulated stepless control signal, adjusting a heating power of the air heater of the air fryer in a stepless manner, so as to maintain the air temperature in the air frying chamber between an upper limit and a lower limit of the preset target temperature.

“Just in time” operational techniques allow equipment of swimming pools or spas to achieve identified water temperatures at specified times. A user may supply information such as a desired water temperature (i.e. a temperature set point) and a time at which the water is desired to be at the desired temperature. After receiving the user-supplied information, software may account as well for certain environmental conditions to devise a suitable schedule for controlling heating of the water of the swimming pool or spa. Adjustments may be made to the schedule based on then-current water temperatures or other changed conditions.
