Troubleshooting Wi‑Fi and connectivity (all Mysa devices)

Last updated: March 27, 2026

If your Mysa is offline, slow to respond, or won’t stay connected, start with the Mysa Wi‑Fi Tool in the app, then work through the quick checks below. For steps that depend on your model (pairing mode, LEDs, removing a device), use your product’s guide linked at the end.

Start here:

Mysa Wi‑Fi Tool

The Mysa app includes a built-in Mysa Wi‑Fi Tool to help find Wi‑Fi and network issues. In the app, this may appear as Network Diagnostics under Support.

To run it

  1. Open the Mysa app.

  2. Tap Support (top right).

  3. Choose Network Diagnostics (Mysa Wi‑Fi Tool).

  4. Tap Run Diagnostics and wait for all checks to finish.

What it checks

  • Wi‑Fi connection — Shows your current network name (SSID). On many Android phones it also shows signal strength (dBm and a quality label) and whether the phone is on 2.4 GHz or 5 GHz.

  • Speed tests — Download, upload, and latency. Poor results can cause disconnects or delays.

  • Mysa services — Whether your phone can reach Mysa’s cloud (API and MQTT). If this fails, the problem may be between your network and Mysa’s servers (firewall, DNS, or ISP).

Tips

  • Mysa thermostats use 2.4 GHz Wi‑Fi only. If the tool shows your phone on 5 GHz, that doesn’t always mean the thermostat is wrong—but your router must have 2.4 GHz enabled and the thermostat must be on that band.

  • The tool may need location permission (OS requirement for Wi‑Fi details). Allow it if prompted so checks can complete.

Why Mysa loses Wi‑Fi

Common causes:

  • Router or modem restart — Power or ISP blip; often resolves on its own.

  • Wi‑Fi password or network name changed — Mysa still has old credentials.

  • New router or ISP — New SSID/password or different Wi‑Fi settings.

  • Router settings — Band steering, MAC filtering, guest networks, or firewall rules.

  • Weak signal or congestion — Distance, walls, or many devices on 2.4 GHz.

Quick fixes (any model)

  1. Confirm Wi‑Fi works — Another device should connect to the same 2.4 GHz network (or the SSID your Mysa uses).

  2. Power cycle the Mysa — Use the correct method for your install (e.g. breaker for line-voltage products). Wait 30 seconds, restore power, then wait 2–3 minutes and check the app.

  3. Same SSID and password as before — If the new router matches the old network name and password, Mysa may reconnect automatically after power cycling.

  4. If it still won’t connect — You may need to put the device into pairing/setup mode and add it again with the current Wi‑Fi password. Exact steps differ by product—use the links below.

Router and home network checks

If problems keep coming back:

  • Band steering — Prefer a dedicated 2.4 GHz SSID or temporarily adjust steering so 2.4 GHz is stable for IoT.

  • MAC filtering — Allow your Mysa using its MAC address (often under Device settings → Device info in the app, or on the product label).

  • Hidden SSID — Supported, but you must enter the name manually during setup.

  • Firewalls — Ensure outbound access isn’t blocked for normal smart-home use.

  • Placement — Move the router or add coverage (extender/mesh) if the thermostat is far away or through heavy walls.

  • Older or overloaded routers — Many 2.4 GHz clients can strain older gear; an upgrade can help.
