@pepson then it is going to be quite difficult for you to work on DIY electronics projects if you don't how to program.

It is a common issue I see in these small cheap meters. There is always the openhardware current meter for what you are suggesting

Aneng an8009 or similar is still a really good buy, 9999 counts is not something you get usually from cheap meters

@boozz serious water leak heppened once in 40 years

Hi
I have been searching if this cable can be used like the cn105 for Mitsubishi devices, but so far I only found libraries for daikin that use IR. Is there really no other way than IR?

There are also some waterproof ultrasound distance sensors you could use

Agreed, the shielded modules can run at full power without any problem

Rfm69 adapter still requires some soldering

Just use mqtt client

That's still on the cheap side, it is still probably a clone. You can consider going with rfm69 radios, they work better
