When designing connectivity into a home appliance, the two most common choices are WiFi and BLE (Bluetooth Low Energy). But with the rise of BLE Mesh — especially BLE 5.4 — the decision is no longer straightforward. Here's how we think about it at Hoags.
The Core Difference
WiFi connects your appliance directly to the internet router. BLE Mesh creates a local device network where appliances relay signals to each other, with one node acting as a gateway to the cloud.
For appliances that need to work even without internet — like a chimney that must respond to voice commands while cooking — BLE Mesh or local BLE is often the better foundation.
When WiFi Wins
- Direct cloud connectivity without a hub or gateway
- High bandwidth needed (e.g., audio streaming, firmware delivery)
- Single appliance without a surrounding device ecosystem
- Consumer expects to set it up in minutes via home WiFi
Our HE1, HE3, and HM1 modules support WiFi + BLE, giving you both. The HE1, for example, provides local voice control over BLE while also maintaining WiFi cloud connectivity simultaneously.
When BLE Mesh Wins
- Multiple devices in the same space (lights, fans, switches)
- Ultra-low power requirement — BLE consumes ~5mA vs WiFi's 100–200mA in active mode
- Cost sensitivity — BLE modules are significantly cheaper than WiFi+BLE combos
- Works offline — mesh network operates without internet
- Range extension through mesh hopping — no dead zones
This is exactly why we built the HE5 and HE6 — cost-competitive BLE 5.4 Mesh modules designed for appliances where WiFi is overkill or too expensive.
HE5 vs HE6 — Which BLE Mesh Module?
Both support BLE 5.4 Mesh with up to 25 devices on a single network and OTA updates. The key difference is the SoC:
- HE5 — Hoags-optimised ARM Cortex-M0+ SoC, embedded IR transceiver, 512KB flash. Best for cost-sensitive appliances that need BLE Mesh + IR control (e.g., ACs, fans with IR remote).
- HE6 — Texas Instruments SoC with Thread and Zigbee 3.0 in addition to BLE 5.4. Better RX sensitivity (-102 dBm vs -97 dBm), ultra-low power (165nA shutdown), and works down to 1.71V for battery-powered devices. FCC, CE, WPC pre-certified.
The Hybrid Approach
For most smart appliances, we recommend a hybrid architecture — a BLE module (HE2, HE5, or HE6) handles local device communication and control, while a single WiFi gateway (could be the manufacturer's app or a smart speaker) bridges to the cloud. This gives you the best of both worlds: reliable local control without internet dependency, plus remote access when needed.
