I have an eWON Cozy 131 (cellular model). I have been losing connection to it constantly. Sometimes it lasts a couple of hours, other times only 30 minutes. The unit has a good cell connection and everything works great while it’s online. When I lose connection, it requires someone to drive to site and cycle the power to it. The unit is grounded properly and the serial starts with 1903, so it’s a new model. Thank you!
