Build a Weather Station with Elixir and Nerves: incorrect light_in_lumens field name (page 43/44)
The field name for light_in_lumens does not alight with the later work done to build the Phoenix server. Either the field name on pages 43 & 44 needs to be changed from light_in_lumens to light_lumens, or the field name light_lumens on pages 51 & 53 needs to be changed to light_in_lumens
