Product technical characteristics
About Bluetooth Function
Bluetooth function is only useful during configuration. After configuration, the device will shut down the Bluetooth network.
About the update frequency of temperature and humidity
1. We used the trigger mechanism When the temperature or humidity change reaches the trigger condition, report the data immediately The fastest update frequency is two minutes. Generally, the data is updated once an hour
2. The sensor cannot set the update frequency,
3. The sensor cannot set alarm, and the alarm function is set on the APP
If you need to update data in real time, please purchase a USB powered version.
About batteries
1. Only LR03-1.5V alkaline battery can be used (1.2V rechargeable battery may cause the equipment to detect wrong voltage and report low voltage)
2. Batteries of different models cannot be mixed
3. Batteries of different brands cannot be mixed
4. New and old batteries cannot be mixed
5. Do not use inferior batteries
Otherwise, 1. configuration failure, 2. battery consumption is too fast
How to obtain high-quality batteries or genuine batteries. Please buy them at regular supermarkets or chain stores over time
Note: After the device configuration is completed, it needs to be placed in a position where the wireless signal is good, otherwise the power consumption of connecting to the network will increase, which will lead to fast battery consumption
About Network Testing
The network will consume a lot of power
To ensure the service life of the battery, the sensor will stop using the network when it does not need to report data
Therefore, it is meaningless to test the network signal of sensors in APP.
Error on temperature and humidity
1. All temperature and humidity sensors will have certain errors, please note
The error of this sensor is ± 1 ℃ and the error of humidity is ± 5% RH
Any value within this range is normal
2. Sensor error and manufacturing process will lead to certain errors between products of the same model
3. According to Newton’s third law, the heat conduction takes a certain time.
Therefore, our sensor needs 30 minutes to be consistent with the room temperature, and the measurement will be accurate.
About Historical Curves
1. The minimum granularity of historical data (daily chart) is 1 hour, and the minimum granularity of exported data is also 1 hour
2. Days of historical data are stored for 7 days
3. The value of historical data is the average value, that is, the average value in a minimum granularity time
Support for third-party smart speakers
1. Because the third-party smart speakers (Google Home/Amazon Alexa) do not have control panels corresponding to temperature and humidity sensors, the temperature and humidity may not be displayed normally on the third-party smart speakers’ APP. But we have opened the voice query function.
Therefore, the current temperature and humidity can be queried by voice
2. Route or automatic process related to temperature and humidity cannot be established on the third-party smart speakers
3. The device does not support Yandex Alice
About Automation
The sensor uses the principle of Edge Triggered
That is, the action can only be triggered if the condition crosses the set condition
For example, when the automatic setting temperature is greater than 25 ℃, then turn on the air conditioner.
1. When the temperature rises from below 25 ℃ to 25 ℃, the automatic process can trigger to start the air conditioner
2. After the automatic process is set, the temperature is always above 25 ℃, and the air conditioner is not turned on.
3. When the temperature drops to 25 ℃ and rises to above 25 ℃, the automatic process will be activated.
For example, when the automatic setting temperature is less than 20 ℃, turn on the air conditioner
1. When the temperature drops from above 20 ℃ to 20 ℃, the automatic process can trigger to start the air conditioner
2. After the automatic process is set, the temperature is always below 20 ℃, and the air conditioner is not turned on
3. When the temperature rises to 20 ℃ and then drops to above 20 ℃, the automatic process will be activated.
FQA
Q: What are the necessary conditions for using it?
A: Firstly, you must have a smartphone to install the app. Secondly, If you purchase a WiFi version, it need WiFi at 2.4GHz and the WiFi router needs to be constantly online. If you purchase the Zigbee version, it requires Tuya Zigbee Hub or Tuya Multi-Mode Gateway.
Q: Does Zigbee Version support third-party gateways?
A: NO, Zigbee Version only supports Tuya Zigbee Hub or Tuya multi-mode gateway. Not supporting third-party gateways, including Zigbee2Mqtt.
Q: How do I know my WiFi router has a frequency of 2.4GHz?
A: Most routers come with a 2.4GHz frequency band, and this information is usually marked on the router’s nameplate. Some routers default to turning off the 2.4GHz frequency. Please refer to the router’s manual to turn on the 2.4GHz frequency.
Q: Can I control it through 2G, 3G, 4G, 5G mobile networks?
A: YES. Operating Smart IR Remote through APP means that as long as your mobile phone can access the Internet (no matter what communication mode), APP can control it.
Q: What do I need to pay attention to when installing it?
A: 1. Please ensure that the signal (WiFi Version required WiFi 2.4Ghz, Zigbee Version required Tuya Zigbee Gateway) at the installation location is good. 2. The sensor is not waterproof and can only be used indoors.
Q: What kind of battery can I use?
A: LR03-1.5V Alkaline battery. Especially in the WiFi version, WiFi 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 testing function on the device properties page always fail?
A: In order to save power, the sensor will shut down the network for sleep when it is not necessary. The network testing function requires the device to be online and requires power consumption for long-term testing, and the battery of the sensor cannot guarantee long-term operation. When testing the network, the sensor is sleeping, 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 the temperature or humidity changes exceed the set value, the triggering mechanism will wake up the sensor to start the network and send data.
Q: Can multiple people use it?
A: YES. There are two methods: 1. You can use the sharing function to share with your friends or family. 2. You can create a virtual home
on the app and invite your family or friends to join.
Q: What do I need to do when configuration fails, I purchased the WiFi version?
A: 1. Check whether the remote control is powered on or not. And ensure that the indicator light of Smart IR Remote is in fast flashing mode.
2. Check whether your mobile device is connected to 2.4GHz WiFi network.
3. Ensure that Smart Life has Bluetooth permission and confirm that the phone has Bluetooth turned on (some phones have low-power Bluetooth in GPS, if so, please ensure that the location information is turned on)
4. Check your network connectivity, make sure the router is working properly.
5. Make sure the WiFi password entered is correct when adding remote control.
6. Confirm that the WiFi router does not have restricted access features, such as Mac address whitelist.
7. If WiFi 2.4GHz and 5GHz use the same SSID, you can try changing the name and have your smartphone connect to WiFi 2.4GHz.
8. If the configuration still fails, please turn off your phone’s Bluetooth, long press the Smart IR Remote Reset Button for 5 seconds to switch the device’s 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, and the APP page will guide you through the operation.
Q: How should I configure my Smart Speaker / Amazon Alexa / Google Home / Yandex Alice ?
A: Smart IR Remote cannot directly connect to third-party smart speakers. They need to provide account links and support through the “Skill” function. You can use the following methods: Smart Life ->Me ->Third-Party Services. But the necessary condition for these is that you have already configured Smart IR Remote to Smart Life.
