5 months of historic data disappeared

Hello. For some reason, my historical data is missing for a large chunk of the year, from May to October. My sensor was definitely operating during all of this period and when I’ve previously looked at the historical data it’s all showed up normally, I was regularly reviewing the average readings over the last 180 days or 360 days. But today it is not showing up for those months.

How can I retrieve those missing readings?

Just to add when I download the CSV data it’s all there for the missing months. But it’s not showing up on the chart.

Hi @Bangkokdi - could you please share your monitor’s serial number via our support form? I’d like to take a closer look to understand what might have happened here.

I have submitted a support form with the serial number. Thank you.

Thanks for the almost complete fix. Will let you know when the May data reappears as it’s still missing.

Hi, just to let you know that I am still missing the data from end of April to early June.

Hello! Sorry for the delay on this. Can you check now? It should be restored.

Yes it’s back! Thanks :blush:
