A steady red light on Joto generally means there is a network connection issue.
If you click Joto’s button and the light flashes briefly before restarting the unit, its almost certainly connection problems.
Have you changed your router or network settings recently?
Maybe its signal strength in your home, try moving Joto’s location to see if its can pick up your wifi from there.
If your Joto doesn’t respond to button clicks you can reply to this topic and we will try to help you.
