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:
- Open the Mysa app
- Tap your thermostat > Settings
- Find the option to re-learn IR codes
- Follow the prompts with your original remote
Wi-Fi Connection Issues
Mysa showing offline:
- Check that your Wi-Fi network is working
- Ensure Mysa is within range of your router
- Try a Wi-Fi reset: Press and hold Up + Down arrows until countdown completes
- 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:
- Turn off the unit with Mysa
- Wait 10 seconds
- Turn it back on with Mysa
- 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
