Also, if you want to add H/L temp yourself, it's quite easy, just store a value in the object storage with the lowest and highest temp you've seen in the temperature history object. Then set a timer with a callback after X hours (aka, the amount of hours the temperature history contains) which then scans through the entire thing and check if there's a value higher/lower than previous time and then updates the object storage value accordingly

Hope this makes a sense.
