MeteoStick / Davis support Domoticz

[spex]

Hi everyone,

I have a question regarding the compability of the MeteoStick to recieve data from the Davis VP2.

I have the following sensors on the Davis VP2:

Connected to the ISS (Basestation)

Temp+Baro
Temp+Humidity
Rain
UV
Solar

Connected to the Davis Transmittor kit:

Wind

The problem I currently have is that domoticz can't recieve any data from the transmittor kit.
Does anyone know an solution for this problem? Attached a copy of the datalog.

Hi spex,

same setup and same problem here.
Did you find a solution yet?

I tried to locate a file for meteostick in domoticz but until now no luck.

I also have 2 UV readings but only one rain.

Rgds.

I just bought a Davis Vantage Pro and i'm afraid to run into the same problem as i plan to separate the anemometer from the ISS with an additional transmission unit. Normally the meteostick listens only to transmitter nr. 1

I have read in the meteostick manual https://www.smartbedded.com/files/manual-en.pdf that it is possible to program the meteostick to listen to up to 8 transmitters.
This is done by plugging the meteostiock into a PC USB port, install a driver for the serial port if necessary and open a terminal program for the serial port.
Using the t- comannd allows the user to specify for which transmitters the meteostick should listen.
e.g. to listen for transimtter 1 and 2 the comamnd is t3.

I haven't tried this yet, because i havenb'nt bought the second transmitter for the anemometer yet.

The Meteostick & Davis_PWS communicate at 868MHz.
Looking at the question, possibly 2 solutions for linking to Domoticz:
1) make an interface/plugin in Domoticz to read the USB-Meteostick.
Requires the availability of the protocol-description for the USB-interface of the Meteostick, and example-files of sniffed communication.
Could result in a plugin comparable with TE923.
2) apply the 868MHz-version of RFLinkGateway, after you convince the Stuntteam to make a plugin for Davis, because not yet in the list of supported devices.
Will require some discussion beforehand, because they will ask that you provide as example a sniffed communication-file and (if possible) a protocol description for the communication from the Davis_PWS.

The Setup/Hardware-selection of Domoticz also mentions RFXCom868, but nowhere at internet a supplier available ......

I plugged the meteostick into an USB port of my Windows PC and checked the device manager if it is recognized as a serial port.
(In my case it was COM 5)
I downloaded a serial terminal for my PC like HTerm http://www.der-hammer.info/terminal/ unzipped and started it.
COM 5 was automatically detected by HTerm.
Klick on Connect
For a better reading resp. sending data to the COM port:

• In the RX section, i choosed "Newline at CR+LF"
  In the input options, i choosed send on "Enter CR"

see attachment:

As described in the manual i entered

• r to reset the meteostick
  t3 for transmitter ID 1 and 2
  o1 for the right format of the data
  and m1 to send the data.

If the ID of your anemometer transmitter is 2, then you should see its data after a while.

For a better reading you can enter o2 in the terminal window.
But for domoticz you need the o1 format.
I couldn't test it by myself, cause i don't have the anemometer transmitter yet.

Meanwhile i got the transmitter for the anemometer, set it to ID 2 and checked its functionality.
It works with the Davis console.
Also the meteostick reports the signal (see minicom output)

But Domoticz recognizes only an UV and a rain sensor on ID 2 (which are not connected)

So it seems that the problems lies inside Domoticz.

Seems we will have to pull a request in Github
