Troubleshooting Wi‑Fi and connectivity (all Mysa devices)

Last updated: July 22, 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).

RouteThis Helps diagnostic tool

For additional network diagnostics, Mysa has partnered with RouteThis Helps, a third‑party tool that can identify pairing and connectivity issues.

  1. Download the free RouteThis Helps app from iOS or Android.

  2. Open the app and tap Device Setup.

  3. If prompted for a code, enter MYSA.

  4. Place your phone next to the Mysa device and stay within close range during the scan (2–3 minutes). Do not minimize the app during the scan.

  5. When complete, provide the eight‑character code to support@getmysa.com for analysis.

Tips

  • Mysa thermostats require 2.4 GHz Wi‑Fi only and cannot connect to 5 GHz networks. Your phone must also be connected to a 2.4 GHz network during setup or re‑pairing. If the tool shows your phone on 5 GHz, switch to 2.4 GHz before adding or reconnecting a thermostat. Your router must have 2.4 GHz enabled and the thermostat must be on that band. If your phone automatically switches between bands, temporarily forget other networks (especially 5 GHz) in your phone’s Wi‑Fi settings to prevent switching during pairing, then reconnect to them after setup is complete.

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

  • Merged networks: Mysa thermostats cannot connect to merged/combined networks where 2.4 GHz and 5 GHz use the same network name. If your router combines both bands under one SSID, you’ll need to create a separate 2.4 GHz network with a distinct name, avoiding spaces or special characters (see Router and home network checks below).

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 / Combined bands — If your router combines 2.4 GHz and 5 GHz into one network name and your Mysa won’t connect, try this process:

  1. Confirm your router has (or can create) a dedicated 2.4 GHz network. Contact your ISP if you need help splitting the bands or setting up a 2.

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

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

  3. Firewalls — Ensure outbound access isn’t blocked for normal smart‑home use.

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

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