Re: RTC battery supply
Has an rtc but not a battery-backed rtc. So you have to implement battery switching and sleep/wake in external circuitry and software.

Re: PCB (or commercial product) with ESP32 + Power Supply + Relay
Not yet, there are not really any end products shipping yet with esp32 inside that I have seen. Probably itead will do "sonoff pro" or something with esp32 eventually. Olimex board has relays but not AC/DC and not in production yet.

Re: [help]spi pin number
They (gpio 6-11) can be used for parallel spi operations in limited cases, hardware debugging, direct programming of the flash chip, possibly slave mode. We complained about the esp8266 modules that didn't break out these pins and eventually got esp-12e/f/d/q. To assume that a gpio is free and clear...
