Problems with Apollo TEMP-1B sensor

I have an Apollo TEMP-1B sensor. I’m using the regular long temp sensor, not the food one. It’s measure pool temperatures. If I run it without sleep (continuous), it measures normal. However, I set it for 1 hr sleep/wake cycles. When I do this, it measures crazy measurements like real high temps (181F). Does anyone experience this and know how to fix it? The board temp is also real low. I’m in FL, it’s like 70F. I have it outdoors but in a waterproof case, under a roof with the sensor wire going into pool out of it.


The manufacturer (Apollo) sent me a customer service ticket response saying they were aware and have been testing it and will be pushing a firmware upgrade today.
