@pandy go for a new rpi3 that works very well.

Yes, it works but it depends on the chip quality: there are some performing better with lower power, it is a matter of doing tests to figure it out, there is not rule to follow with all those counterfeit nrf24 chips around.

You can chain more repeaters. You could set a fixed parent ID in the repeaters so they don't try to jump one.

About NRF24 power, you can also use pa_max and pa_high, it just depends on the quality of the radio module.

@pandy that's definitely a problem. What linux are you using?

go to library manager and install Time library

Only @user2684 can answer that 😀

If it is a tipping bucket if you are receiving too many pulses you either have a bucket too small or you really have a storm raging outside 😀

Are you referring when the sensor is wet and not reporting anything?

What changes are you referring to?

Domoticz is for sure not the best solution, but at least it works and it's easy to setup. There is a random bug where it splits temp+humidity sensors though 😅
