Interested making a Wi-Fi closed (internal) network of a (1) ESP32 Server with (2) or more ESP32 Clients for a solar power load destitution control system within the residence. In module13 Unit 6 describes (1) ESP32 Server with (1) ESP32 Client not (2). Reason for the internal Wi-Fi network is the router periodical loses sink with provider (need to have a stable internal network). Because of the limited range of ESP32 Wi-Fi network would require periodical access to ESP32 Server via the router. If this is possible point me to the necessary RNT courses if available.
