# ESPHome ### Logging Avoid excessive log, or at least avoid excessive log at DEBUG level, but if you look around this project, many of the functionalities will log like this: ```yaml sensor: - id: my_sensor ... on_change: - lambda: |- static const char *const TAG = "sensor.my_sensor"; ESP_LOGD(TAG, "New value: %f", x); // No need to log this, use only when needed if (id(is_uploading_tft)) { ESP_LOGD(TAG, "Skipping any action as a TFT upload is in progress"); // No need to log this, use only when needed } else { // Your code here } ``` ### Page opened When a new page is opened, a script name `page_changed` (whith a parameter `page` containing a string with the page name) is called and that one will call a page specific script named `page_`. In addition, pages with multiple pages (entitypageXX, buttonpageXX and weatherXX) will also call a generic page named `page_entitypage`, `page_buttonpage` or `page_weather` with a parameter `page_number` containing the number of the page called. If you want to execute expecific code when a page is opened, you can extend the functionality of that specific page: ```yaml script: - id: !extend page_changed then: # Code to run when any page is opened - lambda: |- static const char *const TAG = "script.page_changed (custom)"; ESP_LOGD(TAG, "Custom code for page changed"); ESP_LOGD(TAG, "This is the new page: %s", page.c_str()); - id: !extend page_buttonpage then: # Code to run when any buttonpage is openend - id: !extend page_buttonpage02 then: # Code to run when buttonpage02 is opened ``` #### Managing conflicts with Upload TFT The TFT upload is the most resource conmsuming task in this project and should have all the resources available, so when creating something, please take in account: #### Stop your scripts before the upload starts If you create a new script that should be stopped previous a Upload TFT starts, please add your script to the `stop_all` script like this: ```yaml script: - id: !extend stop_all then: - script.stop: my_new_script_id ``` #### Check for upload status before starting any action There is a global `is_uploading_tft` which will be true when the upload TFT process starts, so you can use this in your code like this: ```yaml sensor: - id: my_sensor ... on_change: - if: condition: - lambda: !lambda return (!id(is_uploading_tft)) then: # your code here ``` or: ```yaml sensor: - id: my_sensor ... on_change: - lambda: |- static const char *const TAG = "sensor.my_sensor"; ESP_LOGD(TAG, "New value: %f", x); // No need to log this, use only when needed if (id(is_uploading_tft)) { ESP_LOGD(TAG, "Skipping any action as a TFT upload is in progress"); // No need to log this, use only when needed } else { // Your code here } ``` or if you are setting up a script (largely used in this project) it can just kill itself if `is_uploading_tft`: ```yaml scripts: - id: my_new_script_id ... then: - lambda: |- if (id(is_uploading_tft)) my_new_script_id->stop(); // Your code here ```
