Yesterday the birdhouse experienced some really cold weather with temperatures below -10 °C (14 °F). The temperature readings and voltage sent by the Grasshopper were fine but the weight scale delivered some erratic values (please see the image below). The Murata module and the HX711 are specified to work down to - 40 °C. But it looks like the TAL221 load cells operating temperature is only between -10 and + 40 °C. Once the temperatures went up again the weight scale readings returned to normal. I hope the load cell did not suffer any permanent damage.
