For a workshop I had initially planed to order the 100 kg version of the Mavin NA1 via Maritex / Poland, see also Welche Wägezelle für low-cost-Waagen? - #10 by clemens. I had ordered some test pieces before, I did not test the load cells extensive but they seemd to be ok.
Maritex could not deliver 40 pc. timely, so I searched for alternatives and found the one from Omega. In the end I had not time to check the cells against temperature stability before and I ordered the needed amount for the OpenHive ESP32 / TTGO T-Call SIM800C workshop.
We built around a dozen scales and I asked the beekeeper to put the scales outside with some constant weight. So you can see the scales (arround half is online) by choosing a scale in the drop down and comparing weight and temperature. Grafana dashboard – documenta: Stockübersicht & Bienenwetter
Beginning of the measuring periode you may find hives with a constant weight. In the meantime some beekeeper had put the scale under the hive and the temperature sensor in the hive so we can get no comparison data from this hive.
I konw that Hive 19 had a constant weight from 2021-10-11 11:00 to 2021-10-30 11:30. Changes: 2021-10-17, 11:10 new BME sensor, from 2021-10-31 on scale under a hive. So it may be worth to have a look at the weight and temperature correlation in this dashboard.
Looks like a variability of +/- 400 g before the weight peak on 17th (sensor replacement) and +/- 200 g after. For my feeling a bit too much.
