During the installation (step 2) I cannot find my WIFI in the list of available networks

check whether the wifi reaches the control cabinet in which the clemap product is installed if the wifi router is too far away, install a lan cable, a power line adapter (e g tp link tl wpa4220kit) or a wifi repeater the sensor only supports wifi networks on the 2 4 ghz frequency, if the network is on the 5 ghz frequency, activate transmission on 2 4 ghz via the menu of your wifi router or install a repeater
