I’m trying to display numeric HA entities on a display connected to an esphome device. Display works, but it shows up as nan. This is a re-used ESP module and after having a huge amount of trouble getting the encryption key changed, which is a whole other topic and seems to be a recurring one, now it indicates that the HA API is indeed connecting. This seems to be the main issue people are having when this happens, but this is not the case here. Right now encryption is disabled for testing purposes. When polling the entity state, i’m guessing this should show up in the log? It does not.
