On 2022.4.5, still an issue. I think it is not slow or sluggish, I think it just gets stuck on some random value. Definitely not good when you’re depending on frost/ice warning.
I’ve also had recurring issues with stuck temp reading. Both too low and too high by 5-10 C. Most recently today on 2022.4.5. Reading 1 C when it’s 10 C.
