PST-HW400B Product FAQ<\/span><\/b><\/div>\n<\/td>\n<\/tr>\n
\n
Q1: What is this product?<\/b>
\nA: This is a WiFi Ceiling PIR (Passive Infrared) Motion Detector. It can detect motion and is designed for home or office use.<\/div>\n<\/td>\n<\/tr>\n
\n
Q2: Which WiFi frequencies does it support?<\/b>
\nA: It supports 2.4G Hz b\/g\/n WiFi frequencies.<\/div>\n<\/td>\n<\/tr>\n
\n
Q3: How do I connect the sensor to my Wi – Fi network?<\/b>
\nA: Download the Tuya Smart app from the app store. Open the app, create an account if you don’t have one. Then, follow the in app instructions to add a new device. Select the Wi – Fi vibration sensor and enter your Wi – Fi password when prompted.<\/div>\n<\/td>\n<\/tr>\n
\n
Q4: What if my Wi – Fi signal is weak near the sensor’s location?<\/b>
\nA: You may consider using a Wi – Fi extender or a mesh Wi – Fi system to boost the signal. Ensure that the sensor is within a reasonable range of your router for optimal connectivity.<\/div>\n<\/td>\n<\/tr>\n
\n
Q5: Where should I install this motion detector?<\/b>
\nA: It is designed to be installed on the ceiling for optimal motion detection coverage.<\/div>\n<\/td>\n<\/tr>\n
\n
Q6: How does the PIR motion detection work?<\/b>
\nA: PIR technology detects changes in infrared radiation emitted by moving objects. When an object with a different temperature than the background moves in its detection range, it triggers the detector.<\/div>\n<\/td>\n<\/tr>\n
\n
Q7: How is the sensor powered?<\/b>
\nA: The sensor is powered by 2PCS DC1.5V LR03 ultra alkaline AAA batteries and also can be DC5V USB.<\/div>\n<\/td>\n<\/tr>\n
\n
Q9: How long does the battery last?<\/b>
\nA: Battery life depends on usage frequency and sensitivity settings. Under normal usage and default settings, the battery can last approximately 6 months if trigger 10 times a day.<\/div>\n<\/td>\n<\/tr>\n
\n
Q10: What should I do if the sensor doesn’t connect to my Wi-Fi network?<\/b>
\n1. Check the Basics
\nPower: Ensure the sensor is properly powered.
\nWi – Fi Signal: Make sure the sensor is within range of your Wi – Fi router.
\n2. Reset the Sensor
\n3. Re – add the Device in the App
\n4. Check Router Settings
\n5. Update Router and App Firmware<\/div>\n<\/td>\n<\/tr>\n
\n
Q11: How quickly does it respond to motion?<\/b>
\nA: It has a fast – response time and can detect motion and send signals within milliseconds.<\/div>\n<\/td>\n<\/tr>\n
\n
Q12: Does the sensor work with voice assistants?<\/b>
\nA: It supports Amazon Alexa and Google Assistant.<\/div>\n<\/td>\n<\/tr>\n
\n
Q13. Does it work in the dark?<\/b>
\nA: Yes, since it uses infrared technology, it can detect motion regardless of lighting conditions.<\/div>\n<\/td>\n<\/tr>\n
\n
Q14. Which app should I use to control this device?<\/b>
\nA: You can use the Tuya – supported app. You can download it from the App Store (for iOS) or Google Play (for Android).<\/div>\n<\/td>\n<\/tr>\n
\n
Q15. Can I control the device remotely?<\/b>
\nA: Yes, as long as the device is connected to WiFi and your phone has an internet connection, you can control it remotely through the app.<\/div>\n<\/td>\n<\/tr>\n
\n
Q16. What functions can I perform through the app?<\/b>
\nA: You can adjust detection sensitivity, view motion detection history, set up alerts, and manage device settings.<\/div>\n<\/td>\n<\/tr>\n
\n
Q17. The sensor is constantly sending false alerts. How can I fix this?<\/b>
\nLower the sensitivity level in the app. Also, check if there are any sources of constant vibrations near the sensor (e.g.,
\nappliances) and relocate it if needed.<\/div>\n<\/td>\n<\/tr>\n
\n
Q18. The app can’t find the sensor. What’s wrong?<\/b>
\nEnsure the sensor is powered on and in pairing mode. Also, check your phone’s Bluetooth and Wi – Fi settings, and make sure they are turned on.<\/div>\n<\/td>\n<\/tr>\n
\n
Q19. Can someone else access my sensor’s data?<\/b>
\nAs long as you keep your app account credentials secure, and your Wi – Fi network is protected, it’s very unlikely that others can
\naccess your sensor’s data.<\/div>\n<\/td>\n<\/tr>\n
\n
Q20. What if the device stops detecting motion?<\/b>
\nA: Check the detection settings in the app, make sure there are no obstructions in the detection area, and verify that the device is powered on and connected to WiFi.<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n","protected":false},"featured_media":17701,"comment_status":"open","ping_status":"closed","template":"","meta":{"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"_uf_show_specific_survey":0,"_uf_disable_surveys":false},"product_brand":[],"product_cat":[142,286],"product_tag":[],"class_list":["post-17659","product","type-product","status-publish","has-post-thumbnail","product_cat-automation-accessories","product_cat-motion-sensor","product_shipping_class-smart-sensors","first","instock","taxable","shipping-taxable","purchasable","product-type-simple","add-to-wishlist-after_add_to_cart"],"aioseo_notices":[],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/mazzyautomations.co.za\/store\/wp-json\/wp\/v2\/product\/17659","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/mazzyautomations.co.za\/store\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/mazzyautomations.co.za\/store\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/mazzyautomations.co.za\/store\/wp-json\/wp\/v2\/comments?post=17659"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/mazzyautomations.co.za\/store\/wp-json\/wp\/v2\/media\/17701"}],"wp:attachment":[{"href":"https:\/\/mazzyautomations.co.za\/store\/wp-json\/wp\/v2\/media?parent=17659"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/mazzyautomations.co.za\/store\/wp-json\/wp\/v2\/product_brand?post=17659"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/mazzyautomations.co.za\/store\/wp-json\/wp\/v2\/product_cat?post=17659"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/mazzyautomations.co.za\/store\/wp-json\/wp\/v2\/product_tag?post=17659"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
