Here is an example of the flow with Tomas flow as well.
You must edit the nodes to match with your installation. My evok listens at port 8181 so you must edit that also edit make http responce node with your own ip installation and the nodes for temp sensors…...........
Select all and import it to nodered ! After edit, visit http:// your_unipi_ip:1880/temp and see the temperature page. You must wait a few seconds until evok reads the sensors. Just refresh the page.
