ESP8266 Community Forum

Hi first post! And I'm looking for advice.

I want to build a Thermostat-board with

- ESP8266 (preferred Wemos D1)
- T sensor
- LCD (shield?)
- 2 buttons (UP/Down)
- Battery feed or more preferred: feed of mains (so an 220v AC--> 5v (or 3.3.?v) DC step down converter)
- 220V relay (shield ?)

I don't mind soldering a bit but preferably I click a couple of shields into one board. Problem is: what to get. I've been scouring over banggood and aliiexpress and there are a LOT of shields and modules and I don't even know whether the above configuration can be attached to the ESP (most likely it will, IRC 6 pins for LCD, 2 for the buttons, one ADC for sensor).

Bottom line I'm overwhelmed by choices and underteached in compatibility, hence I'm looking for advice.

EDIT: to give this topic a bit of focus, here some components I'm thinking off:
(is there a way to wrap hyperlinks on this arduino forum? I can't find any way)

ESP8266:

Dual Base Shield:

Step down convertor

Again, I'm quite clueless whether this is all compatible with eachother and whether these are the best choices.

Thank you!

small bumb. It took nearly two days for the approval so this topic has already started to sink away...

Never does it take me 2 days to OK, been doing this 3 years... if you catch me before bed... its 8 hours, if I am awake its 3-4hrs.... Even when I was crazy sick it was not 2 days

Hope you get answers I know people in the past have talked about Thermostats for their homes and furnaces...
