I see where you want to go - but still - how do I pull that information from hassio into the lcd display thats hooked to the esp8266 and how to I show that for the last two door open events.
(When everything works (I thought I start easy) I’m going to replace the limited 20x4 display with a bigger pixel based tft or oled that can hold far more logging then just 2 lines. I need to know the basics first…)
Esphome has home assistant sensor component. But you need entity ID from home assistant. And I know nothing about that.
oke - for now your input has been very useful - thank you
Find all entity- IDs needed here from home assistant and I can help to setup Esphome.
I’m getting there…
I update the circuit around the esp with some fancy leds:
wifi_led, using the output wifi_led_output) - flashes when connecting - I copied that shamelessly from an other thread. Thought would be cool.The display say “active” or “disabled” when the led is either on or off (when there is someone home or not)
The only thing I can’t figure out is how to block id: relay from triggering when id(armed_led_state).state != "on"
I found an example somewhere involving a switch as a template but makes no sense to me.
display:
- platform: lcd_pcf8574
id: mydisplay
dimensions: 20x4

if ( ! id(wifi_signal_db).has_state() ) {
it.printf(0, 0, "Connecting...");
} else {
it.strftime(0, 0, "%d/%m/%Y %H:%M", id(homeassistant_time).now() );
it.printf(18, 3, "%.0f", round( id(wifi_signal_db_pct).state ) );
it.print(0, 3, id(ip_address).state );
}
if ( id(relay).state ) {
it.strftime(0, 1, "%H:%M", id(homeassistant_time).now());
it.print(6, 1, "triggered");
}
if ( id(armed_led_state).state == "on" ) {
it.print(0, 2, " <<< ACTIVE >>> ");
} else {
it.print(0, 2, " >> DISABLED << ");
}

I don’t see anything in your yaml that is triggering id:relay.
And I see your setup quite confusing overall…
Have you considered using Switch/Case method?
There’s also the option to use the LCD Menu Integration for more complex display uses.
Well, this is my first try ever using esphome - If you have ways to simplify 
The relay is a switch so it’s published to HA. In AH a got a button hooked to it.

So, do you have a physical button you press that toggles the relay? I’m confused why your using a Switch and made a button to use in HA? When you create a switch or button in esphome, you will get a switch or button entity in HA automatically and don’t need to create a second one.
An easier way to do it??? Best advice I can give you is marry someone smart that can help you or someone rich that can pay to have someone else do it lol.
euhm yes - the button in HA is coming from esphome obv.
sounds like you got it.
So I’m the only one doesn’t understand this setup.
On yaml there is gpio switch taking care of the relay, but there is nothing triggering it. So the only way to trigger it is to do it manually on GUI.
If you had a button/binary sensor to trigger the switch you could set conditions for triggering.
“So the only way to trigger it is to do it manually on GUI.”
Exactly - and that is what i want - “press” the button of the remote control from my phone using the relay on the esp using the gui.
So add a button to your yaml.
