Hello, does anyone have a tip for a good but inexpensive heating cost meter? there are 2 flats in my house, but in the same heating circuit. i would now like to measure one of the two flats and bill the consumption. does not necessarily have to be calibrated, an accuracy of approx. 1% deviation is absolutely sufficient. Thank you :-)

I am looking for a thermal imaging camera for the iPhone that supports both iPhones with Lightning and USB-C connections and, if possible, does not have its own battery but draws power from the iPhone. Is there anything like this on the market?

So many things are wrong.

Need a solution for a longer time than the iphone battery lasts...

Since 1 June 2019, laser pointers are no longer allowed or only class 1 of which there are almost no available models and if so only cheap products. Most distance measuring devices are class 2 and have a pointing function. Wouldn't they therefore actually also be considered pointers? For the purposes of this section, "laser pointer" means a laser device which, by reason of its size and weight, can be held and guided by hand and which emits laser radiation for pointing, amusement, defence and deterrence purposes." All I really need is a decent pointer to test the refraction of materials but it seems almost nothing is allowed anymore. I think the new law overshoots the mark a bit and I wonder if those responsible were aware of how far-reaching it is.
