I do not think you can run a ESP with a button cell if you plan to have the wifi connection always on and ready to receive connections; I would not even consider AA / AAA batteries for that kind of project.

Thank you eduperez for your kind answer,
Do you think it could work if the other component in the project will work on secondary power source?
Thanks again

I am afraid that the ESP itself may drain too much power from the batteries. Have a look at viewtopic.php?f=32&t=5528, there is a link to a table with the expected power use of a ESP on different situations: even in "modem sleep" mode, the ESP consumes 15mA.

I became an esp8266 theoretical fan very recently and the options (I think !?) it could help me develop.
Theoretical fan because of 2 main reasons –
1. i haven’t laid my hand on one yet…
2. I really newbie on electronic design and process
Nevertheless I decided to try a little project and I would be grateful for some gaudiness.
I would like to use esp8266 as a standalone device which will be connected to 5 components leds/motors - a web service should define for each of them should be ON or OFF.
a. Can It be done?
b. I wish to use the smallest power source- can 2032 will do?
c. Which external USB module to use for the programing?
d. I looked but couldn’t find yet similar project – if you think you have can you please direct me at the right direction?
Thanks in advance
roy
