Instant rain detection

The successor to that, Fibaro Smart Implant that is, has an analog IN as well.

FGBS-222 = “Smart Implant”
Input: 2 0-10V or digital inputs 1 serial 1-wire input

FGBS-001 = “Universal Binary Sensor”
Input: 2 potential-free inputs, 1 digital input 1-wire

Did you found a way to bind the sensor RG-11 into Openhab ? As far as I know the drops are counted. So you have to calculate if it raining or not. How did you managed this?

I bought a RG-9 a couple of months ago from (distributor in mainland Europe). Unfortunately with the old firmware which has slightly less little options as the new firmware. But the main thing is that it has instant detection.

I have connected the serial output of the RG-9 to the TX/RX pins of a Nodemcu running ESPeasy. In Openhab I have connected the serial binding to the Nodemcu and am using a javascript transformation to filter all the incoming messages. When there is no rain, it will output the message “R 0” over serial and when it starts to rain it will output “R 1” up to “R 7” depending how severe the rain is. So basically if it outputs something greater than “R 0” it rains.

That’s a nice sensor, does it also transmit brightness data?
The RG-11 transmit it, but it have no supportet serial interface.

RG-9 does not transmit brightness. But what I noticed on te website is that the RG-11 does have a RS232 interface. Wouldn’t you be able to use that to read values from the unit? The hydreon website gives the protocol instructions on the website.

Hi digdeep76, I just configured the RG11 to “It’s raining mode”, highest sensivity, without darkness sensing, and (AFAIR) monostable+15min. This results in a closed contact whenever it is raining (very reliably, really reacts on first raindrop). I connected the concact to a KNX binary input. For extra safety I have used a standard optocoupler to decouple the signal line from the outside of the building, as well as adding a overvoltage protection to the supply lines.
Unfortunately I cannot detect the amount of rain, but this was anyway not the intended use case for me. I would recommend to look at the serial protocol in case you want to extract all the information.
