Troubleshooting

Solutions for common issues with Mysa for Mini-Splits.

Mini-Split Not Responding to Commands

Check line of sight:

• Mysa needs a clear path to your unit's IR receiver
• Remove any objects blocking the view
• Try repositioning Mysa closer to the unit

Check that Mysa is online:

• The display should be lit
• Check the Mysa app — if it shows offline, see Wi-Fi issues below

Re-learn IR codes:

1. Open the Mysa app
2. Tap your thermostat > Settings
3. Find the option to re-learn IR codes
4. Follow the prompts with your original remote

Wi-Fi Connection Issues

Mysa showing offline:

1. Check that your Wi-Fi network is working
2. Ensure Mysa is within range of your router
3. Try a Wi-Fi reset: Press and hold Up + Down arrows until countdown completes
4. Re-pair in the Mysa app

Can't connect during setup:

• Confirm you're on a 2.4 GHz network (not 5 GHz only)
• Move Mysa closer to your router temporarily
• Check your Wi-Fi password
• Disable VPN on your phone during setup

Temperature Reading Seems Wrong

Mysa sensor location:

• Mysa measures temperature where it's placed, which may differ from where your mini-split measures
• This is normal — Climate+ helps compensate

For more accurate readings:

• Place Mysa at a similar height to where you sit
• Keep away from direct sunlight
• Keep away from heat sources or vents

Unit Beeping Frequently

This is normal with Climate+:

• Each beep indicates Mysa is sending a command
• Climate+ sends additional commands to maintain temperature
• If too frequent, try disabling Climate+ or adjusting your setpoint

Multiple beeps during mode changes:

• Mysa sends multiple commands (power, temp, fan, mode) together
• Your unit beeps for each command received

Using Original Remote Causes Issues

Recommendation: After pairing, use only Mysa or the app — not your original remote.

Why it causes problems:

• Mysa tracks your unit's state based on commands it sends
• If you use the remote, Mysa doesn't know the unit's current state
• This causes commands to fail or set wrong temperatures

To fix sync issues:

1. Turn off the unit with Mysa
2. Wait 10 seconds
3. Turn it back on with Mysa
4. Mysa should now be in sync

App Not Connecting to Mysa

Force close and reopen:

• Close the Mysa app completely
• Reopen and try again

Check your internet:

• Mysa communicates through the cloud
• Both your phone and Mysa need internet access

Try logging out/in:

• Log out of the Mysa app
• Log back in with your credentials

Pairing Fails

IR learning not working:

• Point the remote directly at Mysa's front face
• Hold 6-12 inches away
• Try in a dimly lit room
• Use fresh batteries in your remote

Wi-Fi pairing fails:

• Confirm 2.4 GHz network
• Check password
• Move closer to router during setup

Network Diagnostics Tool

If your device keeps disconnecting or won't reconnect, the Mysa app includes a built-in Network Diagnostics tool that can help identify the root cause.

To run the Network Diagnostics tool:

1. Open the Mysa app.
2. Tap the Support button in the top-right corner of the screen.
3. Select Network Diagnostics.
4. Tap Run Diagnostics and wait for all checks to complete.

What the Tool Checks

The diagnostics tool runs three groups of tests:

• Wi-Fi Connection — Displays your current network name (SSID). On Android devices, it also shows your signal strength (in dBm with a quality rating such as Excellent, Good, or Weak) and whether you're on a 2.4 GHz or 5 GHz frequency band.
• Speed Tests — Measures your network's download speed, upload speed, and latency. Slow speeds or high latency can cause intermittent disconnections.
• Mysa Services — Verifies that your phone can reach the Mysa cloud services (API and MQTT). A green indicator means the service is reachable; a red indicator suggests a connectivity issue between your network and Mysa's servers.

Tip: If the Wi-Fi Connection check reports a 5 GHz frequency band, your phone is connected to a 5 GHz network. Mysa devices only support 2.4 GHz Wi-Fi — make sure your router's 2.4 GHz band is enabled and that your device is connected to it.

Note: The diagnostics tool requires location permission to retrieve Wi-Fi network information. If prompted, allow location access so the tool can complete all checks.
