Problem
Indian device manufacturers who want to ship "smart" products are largely dependent on foreign IoT platforms like Tuya — handing over device data, cloud control, and the customer relationship to a third party. There was no sovereign, white-label alternative that local manufacturers could brand as their own while retaining control of their data and roadmap.
Background
As CEO and Product Lead at Cronlux, I built a white-label IoT device management platform — device provisioning, OTA firmware updates, telemetry, and mobile app control — supporting 100+ connected device types and positioned as a sovereign alternative to Tuya for Indian manufacturers. To ground the strategy in reality, I conducted 300+ conversations with manufacturers and channel partners to validate positioning, pricing, and the lead vertical.
Constraints
- The platform had to scale to 100,000+ devices while staying economical for price-sensitive manufacturers.
- Battery-powered sensors imposed tight power budgets, demanding exceptional firmware optimization on constrained ESP32 hardware.
- Navigating Chinese hardware supply chains and manufacturing processes, including on-ground sourcing and evaluation at the Canton Fair.
- Compliance with data-privacy expectations for a platform handling device data on behalf of many brands.
Product Strategy
The most important strategic shift came directly out of discovery: rather than chase the crowded horizontal smart-home market, I reshaped the roadmap toward regulated verticals — senior care and energy — where connected devices solve higher-stakes problems and command stronger pricing. The platform was built white-label first, so any manufacturer could ship a branded ecosystem on top of shared infrastructure.
Architecture / System Design
The scalable platform was architected as follows:
Devices run optimized ESP32 firmware and communicate with the cloud over MQTT for real-time, bidirectional state. Telemetry feeds an event-driven automation engine, and the cloud services run on auto-scaling AWS ECS — designed to scale to 100,000+ devices.
Key Decisions
- Hardware from spec to production: I took a 16A smart energy-monitoring device from specification to production — defining hardware requirements, negotiating with manufacturers in China (including on-ground evaluation at the Canton Fair), and managing an initial batch of 2,000 units at 10% lower unit cost than off-the-shelf alternatives.
- Pivot to regulated verticals: Based on 300+ discovery conversations, I refocused the roadmap from horizontal smart-home onto senior care and energy, where the platform's reliability and data control are differentiators rather than commodities.
- Local processing vs cloud execution: Edge hubs process routine automations locally, so the system stays responsive and private even when internet connectivity drops.
Lessons Learned
Building a hardware-software platform is exponentially harder than pure software — a bug in software is patched in an hour, but a flaw in hardware tooling can cost millions and delay a launch by months. Discovery also reshaped the entire business: the highest-leverage decision wasn't technical but the pivot away from a crowded market toward verticals where the product could actually win.
Outcome
Architected and launched the white-label platform and product lineup, proving that a sovereign, manufacturer-branded alternative to Tuya is viable for the Indian market — and repositioning the company toward regulated verticals with stronger long-term economics.
