Thanks for the video, it was definitely helpful, I’m watching a few of his videos now.
yeah I think this is the best approach, it reminds me of the saying, “The best way to eat an elephant, is one bite at a time”
Unfortunately some people actually plop that whole elephant on their plate and then choke on it. Internet guides arent always right/updated, cheap chinese components dont always work right or have instructions and you can make mistakes.
There’s no penalties or fines for compiling and uploading code for one component at a time. Im not kidding here, it can take 3-4x longer to troubleshoot a medium/large size project than it takes to do it right the first time.

Thanks for referring to my post and that it was helpful to you. if you want to tinker around to learn, individual components may be fine. But if you want something more complete and ready-made I used this card
I got this two-channel one because my thermostat manages a pellet insert in which the logic when switched on closes the first relay for ignition while the second relay manages the power modulation based on the desired temperature. with that card all I needed was a Dallas DS18B20 temperature sensor and a Nextion touchscreen panel. writing the firmware and managing the panel took some time because on the primary RX TX PINS the panel did not respond, therefore since I needed to connect it to the serial 2 PIN 16 and 17, and since on these PINs who manufactured the board had connected the two relays I had to make a hardware change that allowed me to get my thermostat working well. By virtue of this, if you have a simple boiler, just purchase a module with a single relay

Thanks for the tip with the ready made board, its definitely something to think about, I’m still in two minds at the moment, I already have all the components to create a relay module from a previous load of projects and this post on a Raspberry pi forum goes a long way to helping me create a module, that hopefully one day will soldered onto a custom pcb for this project.
I hope you don’t mind I liked your design for the UI so much I adapted it using the rendering engine in EspHome, as my display doesn’t have a dedicated chip for rendering like the Nextion.

Eeww!! I like that display! Clean and crisp graphics plus its a good size and practical. I always see people using those tiny .96" displays and im over here thinking to myself, " did they actually think that theough? Thats F’ing tiny!"
Do you have a brand/model or a link for that display?
Apologies for the amazon link, but it was a generic ILI9341 TFT display 240x320 (2.8"), so still small but it was cheap and what I needed really.
Amazon is fine. I prefer to pay a little more for the peace of mind and F supporting China and aliexpress crooks.
No worries. Just was curious. Really looking forward to this
And, just where do you think that the Amazon seller gets the parts?

@ GreyLinux - I am seriously impressed. When you are finished, please share the stl files because I’ll bet others will want to copy your project.
What will the relays be switching?

Many of the same sellers sell the same stuff at aliexpress, amazon and ebay as they are all marketplaces. 
You still support China (or Chinese business) the same way but on top you that you spend extra money to make bezoz happy

So, for my use case it will be a single relay, used to switch my heating boiler, to heating ‘ON’ and for my use the boiler doesn’t require any voltage or very low voltage to signal heating ‘ON’ also known as dry contacts. However, depending on the use case it could be potentially used to signal a cooling unit. Although I might design a 2 relay unit for people that require both.
So there has been a massive update to the project, I have the yaml where I think it works well and everything works also I spent all of yesterday soldering the entire circuit to a prototype board and surprisingly everything worked first time.
The updates to the yaml are, incorporating a settings( probably not the best description) page by tapping the cogs icon on the home page, adding an IF statement for changing the HEAT and OFF to a different colour when the other is pressed. Finally the brightness configuration was a bit clunky before and didn’t work as expected so with the help of someone on discord I have remedied this to work perfectly.
This is the updated yaml
## Wiring
## --------
## The SPI pins, MOSI, MISO, and SCK, are shared between the display
## and the touchscreen (and SD card reader).
## I did not wire TOUCH_IRQ (add update_interval: 50ms to touchscreen instead)
## The SD card pins are not connected.
##
## LCD to ESP32 (30 pin or d1 mini) wiring:
## * SCK/CLK to 18
## * MISO/DO/SDO to 19
## * MOSI/DIN/SDI to 23
## * DISP_CS to 33
## * DISP_LED to 17
## * TOUCH_CS to 32
## * DISP_DC to 21
## * DISP_RESET to 16
## * VCC to 3V3
## * GND to GND
##
## * Relay to 22
## * Dallas to 14

and here are some photos of the soldered circuit, complete with working relay and the new UI changes.
admittedly not my finest soldering as my best iron broke so I had to use a very old iron with no heating controls
all powered from 240V mains.
later today I will be working on a circuit diagram that I will post of the complete circuit

Here is the Circuit schematic for the above prototype, its not the best layout, Ive not had much experience creating circuit diagrams. Hopefully its legible enough to gain enough of an insight, plus the pinout from the yaml above should also help.
Glad to see you using female headers and then plugging devices into it. It kind of makes me cringe when i see people solder everything to a prototype board. I learned that lesson quickly and its really convenient being able to pull things off if they need replaced.
Be very careful with separating the heat from the ESP and screen from the temperature sensor. I’m using a smaller ESP8266 and little OLED screen and still had to have a couple of goes to avoid self-heating. My case now looks like this:
The Dallas sensor is behind the “front bars” insulated from the D1 Mini which is in the wall cavity with some expanded polystyrene foam and a plastic “lid”. The vents on the bottom and top channel airflow for the D1 Mini and the screen away from the sensor. I also turned the wifi transmission power right down to avoid heating.

I couldn’t agree more, the other components are cheap and easier to solder/de-solder when needing to be replaced but pin headers on displays or micro-controllers/SOC are a nightmare to de-solder. I will probably have a female pin header for the display on the final pcb also, not only for easy replacement but also, so that I can mount the pcb and the rear case to the electrical back box where my current thermostat is and then mount the display and front cover after.
nice, I like the case very sleek. Yeah I learnt this lesson the hard way, when creating an EspHome temp sensors years ago, I couldn’t work out why my sensor readings were so far off compared to a proprietary sensor I had for measurement.
Don’t apologize. Your schematic is millions of times better than Fritzing crap.
@GreyLinux thank you for taking the time to document your journey - you have helped me tremendously. I’ve been inspired to share my progress as well in case anyone would find it helpful for themselves.
