TODO

• auto reset if start as access point, no connection on telnet and relay isn't turn on
• remove dependency to NTPClient, replace by a countdown
• implement hardware monitoring (for example: free memory)
• implement GET Commands by each SET Command (don't show passwords)
• improve tests schema
• improve logger schema
• design a PCB ?
• Make a generic firmware, then user should be configured the pins instead of relays, buttons ...

Known issues

• mqtt incoming messages are duplicate after reconnect to wifi
