showing all IP addresses given out by the router

[medalto]

im trying to configure Shelly Temp sensor  ( with the cloud bit disabled)  to report to my LAN server 

I think it is getting an IP address from the router , but it is in the greyed-out show more list  . 

so its getting an IP address but not maintaining the connection to the LAN . How can  I establish what IP address i has been allocated  ?

@medalto  Get a LAN scanner. If you're using a Windows PC there's an open source one called AngryIP that'll do what you want.

My Shellys are retired, but using the Shelly software can't you set them to a static IP address (outside of the router DHCP pool).  Most of my remaining smarts though do spend most of their time sleeping!
