Detailed Answer
Not recommended. Phone control (app) for industrial remote control has: 1. Latency/jitter (unstable WiFi/4G); 2. Missing safety certification (no hard-wired E-stop loop); 3. Accidental-touch risk (mis-operation while unlocking the phone); 4. Regulatory issues (no SRRC approval). A dedicated industrial link (470MHz + FHSS) is the compliant, reliable solution. LDER and XINGJIA offer dedicated monitoring apps (monitoring only, no control).
| Phone | Latency/safety risks |
| Dedicated link | 470MHz + FHSS |
| App | Monitoring only |
Note:The control link must be a dedicated remote; phones are for monitoring only.
