I also had an unusually high temperature data point while I covered my Tempest during spring cleaning on one afternoon in May 2024. The high reading ended up being 102.6 F, which is way higher than any other data point over the past 2+ years I have owned my Tempest. I would be in favor of simply deleting all of the data for one particular day. Or as an option, deleting just a single piece of data (temperature, or rainfall, humidity, etc) for one day. In the big scheme of things deleting single points of data doesnāt have an impact on the big picture. However, I have one concernā¦
I have a third-party subscription with the SmartMixin app which reads my Tempest data. I would be concerned if any change in the data process, such as deleting historical data, may cause unexpected data feed issues with other 3rd parties. If the Tempest data ops folks decide to pursue this idea, please also work with your known 3rd parties to try and minimize unexpected errors in their data. Thanks
Yes please and I second this! I have one day with temperature data below -10 which is impossible to occur in the summer. I would like the data on this day deleted very badly. It is ruining the statistics of my station.
Yes, please make this option to be able to delete, a day, a point, a range, somethingā¦ I have a yearās worth of data and Iād really love to be able to delete just the first dayā¦ Thanks, and I appreciate anything that could be doneā¦
I had to clean my unit under running water per Tempestās own instructions a few days ago. After turning it back on again, the unit was showing sustained winds of 50-60 mph with 105 mph wind gusts for two days.
Reached out to support who said that they cannot remove the erroneous data.
Itās ridiculous that this has not been implemented yet, either on the end-user side or support side.
I had an erroneous temperature reading when the battery got low of -28.5 degrees, which is now my record low. Tech support says their is not yet a way to delete this selected data.
My tempest went bad and I now have -40F as max Low.
I will have to delete four years of data because of one bad month
This doesnāt make any sense. Thereās no way to delete a single record from a database? Oh, Iāll bet there is lol.
Even if a user has to create a support ticket and someone at Weatherflow has to run the SQL query manually, that takes about 30 seconds. Their stance on this is truly puzzling.
I agree with the need to delete inaccurate datapoints as well. My station had a failure and it recorded -39.8āF - IN FLORIDA 
Residual reading from the great snow storm of 2025?
