I am currently using domotz to shows when a device is connected. I currently in cell 4 show a green check mark for connectivity, how would I for cell 4 put an x mark for when it is disconnected because right now it does not separate weather it is connected or disconnected and shows. green mark for every device even devices that are not connected. Thanks
