[ESPHome] Fouten in code voor Display Component

[hubertgruber]

Na lang te hebben geprutst wordt het wellicht tijd om toch een beetje hulp in te roepen. Met onderstaande .yaml bestand in ESPHome wil ik twee displays, te weten een SSD1306 en een MAX7219 . Daarop wil ik de waardes van de gekoppelde sensoren laten zien, met de volgende code:

Voorzover ik kan zien klopt het .yaml gedeelte van de code, maar zijn het de C++ regels voor de Display Component van ESPHome waar ik de mist in ga. Ik krijg bij het compileren in ESPHome namelijk de volgende foutmeldingen:

Zouden jullie mij misschien in de juiste richting kunnen duwen voor waar ik moet kijken voor verbetering? Naar mijn weten kloppen de indentaties, maar ik weet het niet meer zeker. Het lastige is dat de ingebouwde ' code checker' van ESPHome niet aanslaat op fouten in de Display Component, dus pas na een halve minuut compileren kan ik zien of een aanpassing heeft gewerkt. Alvast hartelijk dank!

[farlane]

id(homeassistant_time).now

Die now lijkt een functie te zijn, dus dat zou dan

id(homeassistant_time).now()

Moeten worden.

Bij

it.print(0,0), id(font4), "Temperature: %1f°C, CO2: %0.f", id(temperature).state, id(co2).state);

Sluit je de functieaanroep naar it.print na de twee coordinaten:

it.print(0,0, id(font4), "Temperature: %1f°C, CO2: %0.f", id(temperature).state, id(co2).state);

Verder heb ik de ballen verstand van ESPHome

Hartelijk dank!! Dat was de oplossing! Nu nog even uitvogelen waarom de MAX7219 niets weergeeft ook al wordt hij toch gedetecteerd, maar nu zijn er tenminste geen fouten in de code meer!

Ook al is het opgelost, dit past beter in Domotica.
