📡 Best Bluetooth Hubs and Gateways
14 hubs, gateways and Home Assistant Bluetooth proxies that put your BLE sensors, locks and buttons online: SwitchBot, Shelly BLU, Govee, SensorPush, Tuya, ESP32 proxies and USB adapters.

✅ Honest Pros & Cons
Bluetooth Low Energy devices are cheap and run for months on a battery, but on their own they only talk to a phone that’s nearby. A Bluetooth gateway fixes that: it sits within range of your BLE devices and relays them over Wi-Fi or Ethernet, so you get remote alerts, history, voice control and automations from anywhere.
There are two approaches. Brand hubs (SwitchBot, Govee, SensorPush, Shelly) are plug-and-play for that brand’s devices. Home Assistant Bluetooth proxies (ESP32 boards running ESPHome, or a USB adapter on your server) work with many brands at once. This guide compares 14 options across both. Looking for the sensors themselves? See our Bluetooth temperature and humidity sensors guide.
💡 Reality check before you buy: Brand hubs generally work only with their own brand’s BLE devices; a SwitchBot hub won’t relay a Govee sensor. A hub must sit within Bluetooth range of each device, so large homes may need more than one. Home Assistant proxies read many brands’ sensors passively, but active connections (locks, some switches) are limited per proxy. For best results, HA’s documentation favors Ethernet-connected ESP32 proxies over Wi-Fi ones, and a USB Bluetooth adapter should be on HA’s supported list.

🔍 How to Choose a Bluetooth Gateway
🏷️
Match Your Devices’ Brand
Brand hubs are the easiest path, but only for that brand. If you own several brands, a Home Assistant proxy covers more of them with one device.
📍
Placement and Coverage
BLE range drops sharply through walls and floors. Place gateways centrally, and add a second hub or proxy for distant rooms, garages or outbuildings.
🔒
Cloud or Local
Govee, SwitchBot and SensorPush rely mainly on their clouds for remote access. Shelly and Home Assistant proxies can run fully local, which keeps working during internet outages.
🔗
Wi-Fi or Ethernet
An ESP32 shares one 2.4 GHz radio between Wi-Fi and Bluetooth. Ethernet-connected proxies free the radio for Bluetooth and generally scan more reliably.
🎛️
Extra Features
Some hubs add IR blasters for TVs and air conditioners, built-in climate sensors, a screen, or Matter bridging to Apple, Google and Alexa.

❓ Frequently Asked Questions
What is a Home Assistant Bluetooth proxy?
An ESP32 running ESPHome that listens for Bluetooth devices and forwards them to Home Assistant over your network. Multiple proxies around the house extend BLE coverage, and HA automatically uses whichever proxy hears a device best.
Can one hub handle all my Bluetooth devices?
Only if they’re the same brand and within range. Brand hubs don’t relay other brands. A Home Assistant proxy reads many brands, but you may still need several for full-house coverage.
Why does HA recommend Ethernet proxies?
An ESP32 has one 2.4 GHz radio shared between Wi-Fi and Bluetooth. Moving networking to Ethernet leaves the radio free to listen for Bluetooth, which improves reliability, especially for active connections like locks.
Do I still need a brand hub if I use Home Assistant?
Usually not for sensors that HA reads directly over BLE. You may still want a brand hub for features HA doesn’t replicate, such as IR control, the brand’s app, or cloud alerts when HA is down.
Are BLE gateways the same as Zigbee hubs?
No. Zigbee hubs coordinate a mesh network, while BLE gateways relay point-to-point Bluetooth devices. Some, like the Tuya multi-mode gateway, do both. See our Zigbee hubs guide for mesh options.
🏁 Final Verdict: Best Bluetooth Hubs and Gateways
The right gateway for every BLE setup:
🏡 Best Local Control: Shelly BLU Gateway
Buy Here →🔗 Most Reliable Proxy: ESP32-S3 PoE Board
Buy Here →🌡️ Best for Govee: Govee Gateway + 3 H5100
Buy Here →If you’re building around one brand, buy that brand’s hub: the SwitchBot Hub 2 is the most capable, and the Shelly BLU Gateway is the best for local control. If you run Home Assistant with sensors from several brands, a few ESP32 Bluetooth proxies (ideally Ethernet-connected) will cover the whole house for less. Pair your gateway with sensors from our Bluetooth temperature and humidity sensors guide, and see our Home Assistant hardware guide for the server side.
