Smart Tank Monitors by protocol

How do these protocols differ? Show the pros and cons
Bluetooth 2.4 GHz

Pros

  • Pairs straight to your phone with no hub or network
  • Bluetooth LE sips power, so sensors run for months or years
  • Keeps working when the internet is down
  • Home Assistant can extend coverage with cheap ESP32 Bluetooth proxies

Cons

  • Short range, often a single room through walls
  • No remote control unless a hub, bridge, or proxy is in range
  • Bluetooth Mesh has little product support for home automation
  • Many devices work only through the maker's own app

Our take: Fine for one-room gadgets you control from your phone. For whole-house automation, plan on a hub or Bluetooth proxies.
