Yesterday my wifi was down for a few hours and I noticed the 4Pro receiver acting strangely!!
09:00 Wifi was turned off - receiver showing 'Big Clock' correct time.
09:30 Receiver turned itself off/on, reconnected to tx, time changed to 14:30?
12:00 I noticed the the time was now showing 20:00?
12:30 Wifi turned back on - receiver showing correct time.
I don't know if anything happened between 9:30 - 12:00 as I wasn't looking
Any ideas, could it be a bad rtc module?
Hi SR123,
If the receiver isn't able to keep the correct time after a reboot in the absence of WiFi, most probably it is due to an empty battery on the RTC module.
Try to remove the RTC module from the socket and measure the battery voltage.

Thanks,
I removed the module and measured 3.2v on the battery.
I then connected it to an arduino nano to see what time it was reporting,

As you can see the Time is correct but the Day is wrong, so I corrected it,

I found these specs on the internet,Features
- Tiny GPIO RTC
- Works in 3.3V and 5V
- Built-in, non-replaceable CR927 battery
- Supported by Raspberry Pi and Arduino
Specification
- DS3231 RTC IC
- Self-adjust 3.3V and 5V
- Size: 14x16x12 mm
The battery is a lithium 3v so the one on my module seems to be OK.
Also the power didn't go off just the wifi when it behaved strangely?
Hi,
Yes, the battery seems to be good, so the issue you felt may be related with a fail to sync the time with NTP server while the WiFi was down.
While never reported I will keep an eye on it.
Thanks for the report.
Since I also had problems with the time on the 4Pro today, I also measured the voltage of the battery on the RTC module due to the topic, there are only 2.6V left.
Should the RTC module be replaced?

Hi Sun_Dancer,
Before replacing anything, can you please describe which issues with time you faced today?
Time isn't set properly after system startup?
One hour after startup, does it continue not showing the correct date and time?

Hello Werk_ag,
I had the problem that the AQM simply put the time back by 2 hours during operation. I unplugged the device several times and did a reset, but it kept happening. I hadn't changed the firmware and the information about the time zone and time server was correct and identical to the indoor version and this did not show the phenomenon.
Now everything is back to normal without doing anything.
Greetings
