I have a so if a Nano with an Esp8266 measuring t/h and logging to emoncms.

I made the nano sleep between readings but someone suffrage dropping the nano. I've been working with just the esp8266 now and managed to get it to post.

Do you think the esp8266 without sleep, will consuele less power than nano + esp8266 with sleep?

It seems to me because sleep code on nano only sleeps nano. So with my current setup, even if nano drops from 24mA to 6mA, the setup still draws those 6mA on top of the ~170 mA of the esp8266 = 176mA.

Whereas with just the nano it would still be 170mA. And according to this source I could take it down to about 15mA:

Thanks, although Im not using NodeMCU.

NodeMCU is ESP8266 sitting on top of additional circuitry, like power regulator and USB translator chip. The actual "brain" is ESP8266 so any code written for NodeMCU will also work on ESP8266. At the least this article shows you what you can do and how to do it.
