The Universal TV Remote Control project tasked DevsTree with replacing the clutter of physical remotes with a single, intuitive smartphone app. Available on both Android and iOS, the app discovers any Smart TV on the same Wi‑Fi network and delivers full remote‑control functionality—power on/off, volume, channel surf, menu navigation, even launching installed TV apps.

DevsTree engineered a cross‑platform mobile solution that:

1. Discovers & pairs with any major Smart TV brand using a hybrid of SSDP, UPnP, WebSocket and HTTP protocols.
2. Reverse‑engineers proprietary APIs for Samsung, LG, Roku, Android TV & Google TV, implementing custom connection modules and required authentication workflows (e.g., PIN pairing).
3. Implements Wake‑On‑LAN to power compatible TVs back on—capturing MAC addresses during setup and firing “magic packets” on demand.
4. Delivers native UX with Kotlin on Android and Swift on iOS, sharing core protocol logic while respecting platform guidelines.

• Multi‑brand fragmentation – Most third‑party remote apps support one or two TV brands; users expect a truly universal experience.
• Network limitations – Smart TVs drop off the network once powered down, blocking remote power‑on capabilities.
• Cross‑platform UX – Maintain feature‑parity and native performance on Android and iOS.

• Mobile: Kotlin (Android), Swift (iOS)
• Connectivity: SSDP, UPnP, WebSocket, HTTP APIs
• Network Utilities: Custom Wake‑On‑LAN packet generator & MAC discovery
• Analytics & Crash Reporting: Firebase, Sentry

• Broad Device Coverage: Supports 90 %+ of Smart TVs sold over the past decade.
• 5‑Star Adoption: Rapid climb in store ratings thanks to reliability and brand breadth.
• Competitive Edge: Wake‑On‑LAN feature differentiates the app in a crowded marketplace.
