[BUG] RtcXCheckDayChange not working

[AlexanderTonn]

🐛 Describe the bug

• i observed that the relays still in the same condition as the day before, and they didn't switch back to the mppt charger

⁉️ Expected behavior

• after a day change, the relays have to be reset, so the whole solar power can charge the batteries.
