With release 0.57 the jsonrest custom component maybe doesn’t work anymore if the state value of the sensor is bigger than 255 char. I used this great custom component to put the values of multiple json values into different template sensors.
Now I need another solution. The API of tankerkoenig.de only allows 1 request until 10 minutes. I need the price from different gas stations. Simple HA RESTful sensors don’t work with this limitation…
