I have a high gain external wi-fi antenna connected to the esp32 main PCB. That connects to the home / local wifi . It also created an internal bridge wifi for the enclosed miner as it's wifi will suffer due to solar charger EMF noise. Hence connects to SolarBit wifi which is inches away and that bridges out. Miner is users choice and also if his solo or pool mining. SolarBit is the "energy harvester" how you burn the 60watts is personal preference
