Elitech STC-1000WiFi Temperature Controller
The STC-1000WiFi is a value-oriented temperature controller that adds remote WiFi configuration to the popular STC-1000 control platform; it’s a financially attractive upgrade for hobbyists who want remote monitoring without moving up to premium modular systems. Compared with Bluetooth-centric modules, Elitech’s WiFi approach offers broader range and cloud access at a similar or lower price, but it trades off the simple local pairing and minimal-latency control that Bluetooth accessories provide.

The ESP32-C3 DevKit offers an affordable, flexible RISC‑V-based platform with BLE 5 support and a rich set of I/O, making it ideal for custom aquarium controllers that need local processing, sensor fusion, or advanced automation logic. Its strong SDK (ESP-IDF), large community, and low unit price speed development and lower prototype costs compared with specialized mesh modules, though it is not focused solely on RF-centric mesh optimization like Nordic or Silicon Labs. Use it when you want a programmable node that can evolve into a smarter local controller while still participating in Bluetooth mesh topologies.

Review Summary
"The ESP32-C3-DevKitM-1 is celebrated for excellent community support, low cost, and easy development workflow, with many users successfully running BLE projects over extended periods; some note limited RAM/flash versus dual-core ESP32 variants and that advanced mesh features may require extra work. Overall it’s seen as a great value and very developer-friendly for BLE mesh prototypes."

Adafruit Feather nRF52840 Express
The Feather nRF52840 Express is the market-favorite prototyping platform for Bluetooth LE aquarium projects because of Adafruit's documentation, battery-ready Feather form factor, and wide library support that shortens development time. It commands a premium over tiny boards like the XIAO, but that cost buys you plug-and-play power management and a rich accessory ecosystem (FeatherWings) useful when integrating pumps, relays, and waterproof sensors. Compared with industrial modules like RAK's WisBlock, the Feather is aimed at rapid prototyping and maker-friendly deployments rather than scaled production.

The Sonoff TH16 is the market leader on price and ecosystem reach, combining a robust relay rated for heater loads with native temperature/humidity sensor support and wide third-party accessory compatibility. While it leans on Wi‑Fi and the eWeLink cloud for full-featured operation (so it trades some local-only control for ease of use), it delivers excellent value for deploying multiple heater regulators at scale where low upfront cost matters.
