Hi Guys,
i using NodeMCU with 3 ch relay with external wall switch control and temperature sensor connected to it with Tosmata on it. I have used following GPIOS.
Relay 1 GPIO4 D2
Switch 1 GPIO5 D1
DHT11 GPIO01 TX
It works very well, all the switches connected to external wall switch which acts a 2 way switch.
Retains power state on boot
Control via existing wall switches as toggle and update status correctly on home assistant
Running on MQTT
Only problem with tosmata is everyday it stops responding and i need to restart them to work.
if that’s not fixed then:
I am planning to move them to ESPhome but i have very limited knowledge in coding. i have managed to get the below code.
I have tried searching online but couldn’t get much information about how to proceed. I need the same features how its configured in tosmata. Please help if anyone know the coding.

name: living_room_esp
platform: ESP8266

ssid: "xxxxxxxxx"

# Enable fallback hotspot (captive portal) in case wifi connection fails

Thanks Tom for the quick reply.
I tried pasting this code but there seems to be some issue on line it give a red cross.

This
update_interval: 60
Should be this:
update_interval: 60s
Not sure how that happened, I copied it directly from the ESPHome example. Must have just missed the last character.
What are the errors on lines 47, 59, and 71?
EDIT: never mind, I see it. I put the restore option in the binary sensors instead of the relays, try this:

Wow thanks again.
Everything works fine but just on power failure its goes to OFF state, its not restoring the last state on power failure.
I read something about this but don’t know how to add it.

Yeah that’s the issue. As long as you have read the warning and don’t expect the device to lose power that often:
esphome:
name: living_room_esp
platform: ESP8266
board: nodemcuv2
esp8266_restore_from_flash: true ### <-----Add it here ###

Can I ask why?
This has the possibilty of getting out of sync. Before you were guaranteed that the relay would turn on when the binary sensor was on, and off when the binary sensor is off.
If you are using momentary switches instead of toggle switches you can simplify the code to just this for the binary sensors:
binary_sensor:
- platform: gpio
name: 'Switch 1'
pin:
number: D1
on_press:
then:
- switch.toggle: relay1
- platform: gpio
name: 'Switch 2'
pin:
number: GPIO3
on_press:
then:
- switch.toggle: relay2
- platform: gpio
name: 'Switch 3'
pin:
number: D7
on_press:
then:
- switch.toggle: relay3
I am using the following button.
Its not a push button. It will stay in same state until we switch it back and when the circuit is closed it needs to toggle and when its released.
