wiring Elfin-EW11 to Pentair Easytouch

[Jfmillaire]

hi,
I have Pentair Easytouch and tried to wired the EW11 adapter to my J20 com port (remote port) using a RJ45 cable. The device was on, but I could only get this kind of reading when testing with MQTT Explorer e.g. ew11 = -?����-�?���
I tried to reverse the data wired without success. Any clarification would be appreciated on the wiring and/or EW11 config.
Any ideas?

Maybe @rstrouse or @tagyoureit can help.

I think you may be overthinking the abilities of the MQTT server on that device. While it can give you modbus registers you need a script installed on it to get any data. Even then it will output information that will need to be decoded. If you want MQTT capabilities from your EasyTouch you should install njsPC and a mosquitto broker. Then you will actually see viable data from your connection. Modbus output is pretty useless if you don't already have the protocol decoded. See the MQTT section of this guide.

I would have said exactly the same thing.. assuming I had the slightest clue what you guys are talking about...

Hi,
I'm running poolcontroller on a Windows machine, MTTQ on HA running and received this error when trying to connect to Elfin-EW11 WIFI:
Error opening port 0: Opening /dev/ttyUSB0: Unknown error code 3.

 

[rstrouse]

If you are connecting to the Elfin adapter it will be a network port not a local port. Change the primary port in the General => RS485 Port tab to network then provide the ip address and port in the address.

I missed it when reconfiguring. Configure using IP and port 9801 but getting this error: Unable to open Socat Connection to <ip EW11>

 

[rstrouse]

The documentation for the adapter will likely also have a tcp port. You must supply that as well.

Interesting device, will be interested to see how this works out.

 

[rstrouse]

There are quite a few folks using them.

 

[Jfmillaire]

HI, I made some progress....well, maybe. I have received packets but not status (successfull or not). You rhelp would be greatly appreciated.

 

[rstrouse]

I do not have one of these but lets first make sure you are getting proper RS485 to the transceiver. Flip the RS485 wires and check to see if we start getting valid packets. If the bits are flipped it will send data that is basically inverted. So a 0 will be a 1 and a 1 will be a 0. If this does not show successful receipts then flip them back over. I cannot tell you how many USB adapters we have seen that are incorrectly documented for this.

When we get this working please let me know what settings you have in the adapter configuration. In every case with these, folks leave that part out so I cannot share what the settings were that they used. The documentation is less than adequate. I assume that you have the adapter configured in STA mode or you wouldn't be receiving any bytes.

In the port settings on the adapter side make sure you have the following set up:
Baudrate: 9600
Data Bits: 8
Stop Bits: 1
Parity: NONE
Flow Control: Half-Duplex

If there are choices between MODBUS and RS485 raw ports you want RS485. Your equipment does not speak MODBUS. There are many configuration pages and almost none of them appear in the manual. Maybe show the configuration pages here and we can figure out which settings are needed.

Ok on the dropdowns under the Socket group what are your options for
Socket Name
Protocol
Rout

I am guessing you do not want to route the log to the socket. It should be sending the raw UART data.

 

[Jfmillaire]

Socket name "netp" is the only selection.

 

[rstrouse]

First select uart as the route. I have heard that there are problems in their interface sometimes not saving but verify that has stuck by restarting the adapter and reloading the page. Then after that if the comms don't start working choose WEBSOCKET for the protocol and again verify that the settings took.

 

[Jfmillaire]

UART was already selected. I tried to create a websocket connection but the information to supply is very different.

 

[rstrouse]

Websocket looks like it is trying to set up a websocket client. That isn't right. The only thing in that list that makes a modicum of sense is TCP-SERVER. This is a different screen. What is under the netp tab at the top. Is it possible that the netp configuration is the server side and any additional ports you add are client ports?

 

[rstrouse]

I tried to see if I could buy one of these things but all of them don't have a delivery date until the end of next month. Boo!

I finally got it to work. Here's my Elfin-Ew11 setup. I believe my mistake was not to use the twisted pair of my Cat5 cable (e.g. blue-white/blue). I've setup my EW11 with AP+STA, which connect to my wifi and kept the internal wifi access for troubleshooting.
