Technical characteristics

About refresh rate
1.the sensor uses a trigger mechanism. when the temperature or humidity changes to the set value, the sensor will report the data immediately. generally, the data is updated once per hour.
2.the sensor cannot set the update report data frequency.
3.the sensor cannot set the alarm. the alarm function is set in the app.
If you need to update data in real time, please purchase a usb powered version (th06/th16).

About the proper selection and use of batteries
1.only lr03-1.5v alkaline battery can be used (1.2v rechargeable battery might cause the equipment to detect incorrect voltage and report low voltage).
2.batteries of different models or brands cannot be mixed.
3.new and old batteries cannot be mixed.
4.it is prohibited to use inferior quality batteries.
Otherwise: 1.configuration failure; 2.battery consumption is too fast.
How to get a high quality battery please buy from a regular supermarket or supermarket chain.
Note: after the device configuration is completed, it is necessary to place it in a position where the wireless signal is good; otherwise, the signal strength of the device will increase, causing excessive battery consumption.

About network testing
Devices that use the network consume a lot of power. to ensure battery life, the device will stop using the network when it does not need to report data.
Therefore, it is pointless to test the network signal of the sensors in the application.

Error in temperature and humidity
1.all temperature and humidity sensors will have certain errors, please note. the temperature error of this sensor is ±1.℃, and the humidity error is ±5% rh. any value within this range is normal.
2.sensor error and manufacturing process will be encountered, and there will also be some errors between products of the same model.
3.according to newton's third law, heat conduction takes a certain time. the sensor needs 30 minutes or 1 hour to be consistent with the ambient temperature and the measurement will be accurate.

Historical temperature and humidity curve.
1.the minimum granularity of historical data (daily chart) is 1 hour, and the minimum granularity of exported data is also 1 hour.
2.historical data days are stored for 7 days.
3.the value of historical data is the average value. that is, the average value of a minimum granularity time.

Support for third-party smart speakers
1.because third-party smart speakers (google home/alexa) do not have control panels corresponding to temperature and humidity sensors,
Therefore, the application of third-party smart speakers may not display temperature and humidity correctly.
But we have developed the voice query function. therefore, the current temperature and humidity can be queried by voice.
2.a route or automatic process related to temperature and humidity cannot be established on third-party smart speakers.
3.the device does not support yandex alice.

Temperature and humidity activation mechanism in automatic processes
We use flank trigger (et)
That is, the action can only be activated if the condition crosses the established condition.
A: for example, turn on the light when the automatically set temperature is higher than 25.℃.
A.1.when the temperature rises below 25℃ to 25℃the automatic process can activate the power light.
A.2.after setting the automatic process, the temperature is always maintained above 25.℃, and the lamp is not on.
B: for example, when the automatically set temperature is less than 20℃turn on the light.
B.1.when the temperature drops from more than 20℃ to 20℃the automatic process can activate the start light.
B.2.after setting the automatic process, the temperature is always kept below 20.℃, and the lamp is not on.

When will the battery drain quickly?
1.the correct type of battery was not selected or the battery is mixed.
2.the sensor will be installed in the place where the ambient temperature or humidity changes drastically. in this environment, the device will start the network frequently to report data.
3.the sensor is installed in a low temperature environment for a long period (for example, less than 0℃the battery performance will quickly decrease at this temperature.
4.the sensor is installed in a place where the network signal is very weak. when the network signal is poor, the equipment will increase the signal transmission power, resulting in higher power consumption.
5.the equipment remains in a high humidity environment for a long time, which will corrode the battery and cause leakage.

Frequently asked questions

Q: what are the necessary conditions for its use?
A: first, you must have a smartphone to install the app. second, if you buy a wi-fi version, you will need a 2.4ghz wi-fi network and the wi-fi router must be constantly connected to the internet. if you buy the zigbee version, requires tuya zigbee hub or tuya multi-mode gateway.

Q: why do we need to use new batteries when setting up?
A: it should be noted that wi-fi connections consume a lot of power. during the setup process, the device must keep the wi-fi function activated. if old batteries are used, the device may not work properly due to a decrease in the battery power. ultimately, this leads to a configuration failure.

Q: how can i tell if my wi-fi router has a 2.4ghz frequency?
Most routers come with a 2.4ghz frequency band, and this information is usually marked on the router's nameplate. some routers disable the 2.4ghz frequency by default. consult the router's manual to activate the 2.4 ghz frequency.

Q: can i control it via 2g, 3g, 4g, 5g mobile networks?
A: yes.operating the smart ir remote control via the app means that as long as your mobile phone can access the internet (regardless of communication mode), the app can control it.

Q: what should i pay attention to when installing it?
One: 1.make sure the signal (wi-fi version required wi-fi 2.4ghz) at the installation location is good.2.the sensor is not waterproof and can only be used indoors.

Q: what type of battery can i use?
A: lr03-1.5v alkaline battery. especially in the wi-fi version, wi-fi connections require a lot of power, so it is necessary to have a high-quality battery to maintain its normal operation, and our product has a low battery warning.

Q: why does the network test function on the device properties page always fail?
A: to save power, the sensor will disconnect the network in sleep mode when not needed. the network test function requires the device to be online and requires power consumption for long-term testing, and the sensor battery cannot guarantee long-term operation. when testing the network, the sensor is idle, so it will fail and we believe it is also meaningless. of course, the sensor will start reporting data at a fixed time, or when temperature or humidity changes exceed the set value, the trigger mechanism will wake up the sensor to start the network and send data.

Q: why can't i see the screen clearly after tilting it?
A: yes.these types of screens have an optimal viewing angle, and our product has the widest viewing angle among products of the same type.what is your viewing angle of 50?°.

Q: can multiple people use it?
A: yes.there are two methods: 1.you can use the share function to share with your friends or family.
2.you can create a virtual house in the app and invite your family or friends to join.

Q: what should i do when the setup fails? if i buy a wi-fi version.
A: 1.check whether the remote control is on or not.and make sure the indicator light of the smart ir remote control is in fast flashing mode.
2.check if your mobile device is connected to a 2.4ghz wi-fi network.
3.make sure smart life has bluetooth permission and confirm that the phone's bluetooth is turned on (some phones have low-power bluetooth in gps; in that case, make sure location information is turned on).
4.check your network connectivity, make sure the router is working properly.
5.make sure the wi-fi password entered is correct when adding the remote control.
6.confirm that the wi-fi router does not have restricted access features such as mac address whitelist.
7.if the 2.4ghz and 5ghz wi-fi use the same ssid, you can try to change the name and connect your smartphone to the 2.4ghz wi-fi network.
8.if the setup still fails, please turn off your phone's bluetooth, long press the reset button on the smart ir remote control for 5 seconds to change the device indicator light to slow flashing mode, and then add it using ap mode.select the slow flashing indicator light option on the add page to enter ap mode. the app page will guide you through the process.

Q: how should i set up my smart speaker/alexa/google home/yandex alice?
A: the smart infrared remote control cannot connect directly to third-party smart speakers. they must provide account links and support through the "skill" function. you can use the following methods: smart life ->i ->third-party services .but the necessary condition for this is that you have already set up smart ir remote in smart life.

Q: why are third-party pages different from smart life pages?
A: we are using tuya solution, and the pages in smart life are customized. but neither we nor tuya can customize third-party pages, we can only use their internal default page display.
