Hi,
I have the NodeMCU DEVKIT V0.9 05/12/2014.
I connect to NodeMCU on ttyUSB0 with a laptop running Linux (Lubuntu).
I programme the chip with init.lua using luatool.
I am going to strap the NodeMCU to the back of my Honeywell Wireless heating controller, a CM921, and wire GPIO 1 to a switching transistor which will short the manual switch on the heating controller, for one hour, when I click the NodeMCU web link on my phone, while I am out.
The idea is to be able to turn the heating on while out, so it is warm when I get back.
I am going to power the NodeMCU from the heating controllers two AA 1.5 V batteries; that's 3 volts.
Can I do that by attaching this power source to one of the NodeMCU 3v3 pins?
So that the heating controllers battery life is necessarily conserved I only need the NodeMCU to operate in RX ultra low power mode.
How do I set the NodeMCU to operate in ultra low power mode?
How do I set the NodeMCU to operate in RX mode only?
Thanks
