tibber_price's Issues

Doesn't work...

Hello,
it looks, that your programm doesn't coomunicate with Tibber, because of the Certificate.
Do you want to fix it?

Error parsing JSON response

Hallo, would like to build a display like so, but serial puts out an "Error parsing JSON response" error.
What could that be? Many thanks

{"query": "{viewer {homes {consumption(resolution: HOURLY, last:0) {pageInfo {totalCost totalConsumption}} production(resolution: HOURLY, last:0) {pageInfo {totalProduction totalProfit}}currentSubscription {priceInfo {current {total}}}}}}" }
{"data":{"viewer":{"homes":[{"consumption":{"pageInfo":{"totalCost":0,"totalConsumption":0}},"production":{"pageInfo":{"totalProduction":0,"totalProfit":0}},"currentSubscription":{"priceInfo":{"current":{"total":0.2659}}}}]}}}
