Solar panel data on a telephone


I connected a CP-6941 Cisco phone with the house’s Asterisk running on the UDOO, and I set the idle page to a custom page on my Energy Monitor so that now, after 5 minutes of inactivity, the phone displays the power produced by solar panels and the amount of power used by the house as well as other data. The same phone can also be used as any other phone in the house to make calls, open the gate, answer the doorbell’s interphone and make calls via a mobile through bluetooth.
