ESP8266 + Nextion: Cannot send message because of TCP buffer space #1075

Closed Axellum closed 4 years ago

Axellum commented 4 years ago

Operating environment/Installation (Hass.io/Docker/pip/etc.):

In docker, Debian 10.3 in box internet (VM). ESP (ESP32/ESP8266, Board/Sonoff):

ESP8266 nodemcuv2 uart screen Nextion Affected component:

https://esphome.io/devices/nodemcu_esp32.html

Description of problem: Hello, I can't figure out why I got an error [api.connection: 670]: Cannot send message because of TCP buffer space when I exceed a certain number of sensors on the yaml of my esp. I discovered the coding of home assistant and esphome, I am not sure that it is a bugg (but I think seen what I found on the subject) or an error on my part. If you ever need, I put my code on github: https://github.com/jeelabs/esp-link/releases/tag/v2.2.3 The problem happens to me when I transfer the image number for the rain icons every 5 minutes over 1 hour of weather in France, but I'm not sure it will be linked ....
