| PST-PW02 Product FAQ | |
| Q1: What is the main function of this clamp? A: It is a smart device that monitors two-phase AC current in real time, transmits data via WiFi to the Tuya Smart/Smart Life app, and supports remote monitoring and overcurrent alarms. |
|
| Q2: How does it measure current? A: It uses a non-invasive clamp-on design—simply clamp it around the live wire; no need to cut or disconnect the cable. |
|
| Q3: Does it work with 5GHz Wi-Fi? A: No, it only supports 2.4GHz Wi-Fi networks. |
|
| Q4: Can I control it when away from home? A: Yes. As long as the switch is connected to Wi-Fi and your phone has an internet connection, you can control it via the Tuya/Smart Life app. |
|
| Q5: Can I monitor current data remotely? A: Yes, as long as the device is connected to WiFi, you can view real-time current data via the app from anywhere with an internet connection. |
|
| Q6: Can multiple users control the device? A: Yes, you can share device access with family members via the app. |
|
| Q7: How to connect to voice assistants like Alexa or Google Assistant? A: Open the Alexa/Google Assistant app, enable the Tuya/Smart Life skill, log in with your Tuya account, and discover the module. Then you can voice-control your lights. |
|
| Q8: What if the module can’t connect to Wi-Fi? A: Check if the Wi-Fi is 2.4GHz, the password is correct. Reset the module (find the reset method in the manual, usually pressing a reset button until the indicator flashes), then retry setup. |
|
| Q9: Does it support scene linkage with other Tuya devices? A: Yes. You can set up scene linkage in the Tuya/Smart Life app to have the module work with other Tuya smart devices. |
|
| Q10: Does it have a timer function? A: Yes. In the Tuya/Smart Life app, you can set scheduled on/off times for the switch. |
|
| Q11: Does it need a hub? A: No, it connects directly to your Wi-Fi network, so no additional hub is required. |
|
| Q12: Can it send alarms? A: Yes, it supports overcurrent alarms. You can set a threshold in the app, and it will send notifications if the current exceeds this limit. |
|
| Q13: Does it work with three-phase systems? A: No, it is specifically designed for two-phase systems. For three-phase monitoring, use a multi-channel model. |
|
| Q14: What happens if the wire diameter is larger than the clamp opening? A: Do not force it—use a model with a larger clamp opening to avoid damaging the device or affecting accuracy. |
|
| Q15: What if the app can’t find the switch during setup? A: Make sure the switch is in pairing mode (indicator flashing rapidly), your phone’s Bluetooth is on, and you’re using a 2.4GHz Wi-Fi network. |
|
| Q16: Does it support multiple languages in the app? A: Yes, the Tuya Smart and Smart Life apps support multiple languages. |
