I tested all three of my Govee sensors this weekend as I typically do every few months and my findings were really frustrating.
My first calibration was with a 69% Boveda pouch in an airtight container. After calibrating my sensors to 69% I found two to be less than 1% low and the third (a puck) was almost 20% low. This is how they have read since I bought them a few years ago.
Just out of curiosity, I put all three in my Aristocrat reading 69% and after 48+ hours saw them read 66.1%, 68.6% 73.2%, all sitting right next to each other. The lowest was calibrated at -16.9% to match the one at 68.6% which was 0.1% off. I've had people tell me you can’t calibrate them that much so I attached a screenshot. My target humidity level for the Aristocrat at 68%.
I decided to try a second calibration this time with a salt test. All three went into the container with the same readings (68.6%) and after a couple of days I again saw a wide range of readings. Today the sensor below started sending crazy readings every 10-15 seconds with huge temperature swings of 50+ degrees in my 67 degree living room. I changed the batteries and the screen subsequently went crazy as you can see in the pic, and it hasn’t sent any data since, even though connected to Bluetooth and WiFi. I deleted the device and reconnected it with no help. This particular sensor was reading closest to 0% before it went nuts.
I use engineered crystals in the two desktops and a HumiCare EH+ in the aristocrat and have been happy with how they consistently maintain humidity for the long haul, the sensors help to alert me when I need to add water. I just can’t find anything consistently accurate. I’ve tried the Cigar Oasis Caliber and they are junk too. I love having the info in an app at my fingertips so I wonder if SensorPush is the answer at twice the price.
