Troubleshooting
Last updated: June 16, 2026
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
