To clarify, it sounds like you want to show the value of a Home Assistant (HA) sensor, some temperature value, which we will call temp1 for our discussion. If you want to grab any sensor value that is defined in HA, refer to Kevin's example starting on line 123 (minus comments:
sensor:
- platform: homeassistant
id: back_yard_temperature
entity_id: sensor.back_yard_sensor_temperature
You define a new ESPHome sensor stating it is based on one from HA. You can give it whatever ID you want to refer to in your YAML, but remember to match the HA id exactly in the entity_id field.
Let's assume you did that and your sensor has the id: "temp1".
To display that in a lambda expression, you need to get the value from the sensor and then knowing it is most likely an integer, you need to cast that to a string to display. So in your line above that goes like this:
- lambda: |-
id(ledkey1_display) = "temp1" + esphome::to_string(id((temp_1));
You are setting the value of the variable ledkey1_display, which is a string. You are trying to assign the concatenation of the literal string "temp1" which gets displayed and what looks like the correct way to refer to the value of temp1 (assuming the underscore is a typo) and properly cast that value to a string.
My best guess, is that you just didn't properly define the value of temp1 as a sensor from HA. Feel free to share where you tried to define that if you need help,

Hi Kevin
First of all, I would like to apologize for my English. My name is Maciek and I am a beginner HA user. While browsing YouTube, I was inspired by your led&key project with TM1638 on ESP. I made a copy adapting it to my assumptions. Unfortunately, I lack knowledge and experience and I don't know how to display an additional HA entity after pressing the button. In the idle state, the clock and external temperature are displayed in the same way as yours. In the ESP configuration, I have defined the temp_1 sensor and in the lambda I am trying to enter:
and an error pops up.
if I type only:
id(ledkey1_display) = "temp1"then after pressing the button, the text temp1 is displayed
Can you please tell me where to look for a solution?
Thank you and best regards
Maciek
