Does anyone know how much power the ESP consumes in AP mode? I think this would be a useful figure for everyone interested in working on a low-powered ESP server.

Thanks

Tye also has a page with more detailed treatment on this topic.

In my case in AP mode it averaged 80mA. I tried all sorts of ops such as wifi.setsleep(2) and even without any connection it hovers at 70mA. The best mode is deepsleep, but it will not be worthwhile for an AP solution.

The only thing you could do is turn the AP off and only wake-up periodically and synchronize that with the clients. But then maybe you should look into the new mesh firmware...
