Yesterday I got my SlimmeLezer in the mail and today I tried installing it. Since it came with no instructions I thought I had to create a configuration using the ESPHome addon using this: slimmelezer.yaml.
Edited the file to contain the WiFi SSID and key and tried installing it.
That did sort of work, it flashed fine but it did not connect to WiFi. Status of it is offline.
So, I am doing something wrong. Probably something simple. Can somebody help me?
How did you flash it?

Using the ESPHome addon in home assistant
I meant with which device. Via the browser https direct method or is it connected via an UART to the HA itself? and what did the log say?
Did you disconnect it from the UART before resetting it? Sometimes it will not boot when still connected.
Also: GitHub - zuidwijk/dsmr

Via the browser with the device connected via a USB cable to the RPi4.
I will try replugging the device
Unfortunately that did not solve my issue. No new device in my wireless network 
What does the log say after the upload?
Just load in the code from ESPHome.
Also do you have a secret file or did you remove the !secret from the code you pasted

Fill in the ota, ssid and pw so you can see if it connects.
ota only needed if you want to use wifi upload for next tests.
Looking at the code.
wifi:
networks:
- ssid: "SSID"
password: "WirelessKey"
Stands out as a format never saw in my codes. But could be old code.
Also look at the ESPHome link, the code for reading out is updated as its integrated in ESPHome now.
Are you located in Luxembourg?

I am located in the Netherlands so the whole part about the decryption key can be dropped.
According to this the wifi syntax seems fine.

Enabling anything else and the yaml is not valid or if it is, the device seems to hang on boot.
Of course it wont show up in HA as you have not enabled the api.
And you are still not using the code from the ESPHome but the original code you linked.
So a couple of things:
- api is not set, so in integration it will not show up.
- You will need to figure out what info you want to have and make the yaml file according to that.
- Trim that code a bit. Still alot of stuff in there that is pointless. Like the wifi_info.
First part of the code:
esphome:
name: slimmelezer
platform: ESP8266
board: d1_mini
# Enable logging
logger:
# Enable Home Assistant API
api:
ota:
password: "password"
wifi:
ssid: "ssid"
password: "password"
fast_connect: true
# Enable fallback hotspot (captive portal) in case wifi connection fails
ap:
ssid: "slimmelezer"
password: "g6ThtO24Kc4M"
captive_portal:
This will set the name and rest of the basic info to boot and be reachable, and connect to HA
For the rest of the code you will need to add the sensors and whatever else you want.
sensor:
- platform: dsmr
energy_delivered_tariff1:
name: Verbruik Tarief Laag
energy_delivered_tariff2:
name: Verbruik Tarief Hoog
Adjust and add whatever sensors you want in to show up in HA

Hey did you get this working with the slimmelezer.yaml template from GitHub? I think I’m having the same issue over here: How to set up Slimmelezer with Home Assistant for dummies
When I use this slimmelezer.yaml:
substitutions:
device_name: slimmelezer
device_description: "DIY P1 module to read your smart meter"
esphome:
name: ${device_name}
comment: "${device_description}"
platform: ESP8266
board: d1_mini
# Enable logging
logger:
# Enable Home Assistant API
api:
ota:
password: !secret ota_password
wifi:
ssid: !secret wifi_ssid
password: !secret wifi_password
fast_connect: true
# Enable fallback hotspot (captive portal) in case wifi connection fails
ap:
ssid: ${device_name}
password: !secret ap_password
captive_portal:
web_server:
port: 80
uart:
baud_rate: 115200
rx_pin: D7
dsmr:
id: dsmr_instance
Then the logging always hangs at this point. I’ve tried pairing down the yaml a lot to narrow down the root cause but no luck so far. Will try to go further later.

You are absolutely right. Stubborn first timer here 
I think we both like to mess around with things. This information is also in your thread, but upload the default yaml, connect it to your smart power meter, log into it using your phone, enter wifi credentials and simply wait for it to show up in home assistant. No need to mess around with yaml’s.
This will not work for me, without the dsmr: declaration.
That will not work without the uart: entry.
That gives me an error on the D7 pin.
I’m lost atm
Update: I was connecting it to the HA server itself and installing it from the ESPhome dashboard which is not the way to go. Flashed the firmware from the zuidwijk productpage with esphome-flasher and things look better. I’m getting readings in the sensor entities, but the energy dashboard itself is reporting ‘Unexpected state class’.
There were some changes in HA 2021.9 for the state_class of energy sensors. That got also changed with the latest firmware of slimmelezer (I think 2 days ago).
The firmware in my slimmelezer worked with HA 2021.8, but gave a similar error about state_class after updating HA to 2021.9. This was solved by updating slimmelezer firmware (I used the yaml from Github, but OTA file from product page should also work).
