Re: Bwired Opentherm Gateway solution with EZL-70

Post by Bwired »

I had some questions about how exact to connect the EZL on TTL level to the OTG (OTG without the MAX232)

Configure the jumpers on the EZL-70 for TTL
Black = GND on EZL
Yellow = TX connect this to RX on TTL connecter the EZL
Red = RX connect this to TX on TTL connector the EZL

Run the ezConfig tool for the EZL-70
Click on search all and the tool will show you the EZL's on your network.
make the following settings

for pin settings and EZL configuration see here http://www.domoticaforum.eu/viewtopic.p ... =15#p60164

I just found this topic when creating a new topic on how to add an EZL-70(A) to the OpenThermGateway to get ethernet support.

I would like to by one http://www.antratek.nl/Ethernet-TCPIP-S ... dules.html instead of buying and additonal usb to com converter (the current one seems to be buggy) but what exactly do i need

Code: Select all


- One EZL70A (http://www.antratek.nl/pdf/ds_ezl70aen.pdf)
- jumper cables ?
- additional power supply ?
- RS232 to ethernet driver for Windows XP

Running HS3PRO on PC with Z-Wave / OpenTherm / Plugwise / RFXcom / MQTT / XAP400 / Logitech Media Server and Squeezelite on PI`s

I dont understand your questions, everything is in this topic.
If you want to use the comport driver its on the EZL site

This module has a TTL input, so I left the MAX232 out and connected the PIC directly based on TTL via 3 wires.
Cool stuff. I was thinking of doing the same with a ioshop.nl/shop/127-serial-to-ethernet/2 ... tem_id=206. It's a bit more pricy but, Linux support is a must for me (I am Windows-handicapped: cannot work with it). Or do you know any serial2ethernet modules that do have Linux support?

This is hardware, so it is OS independent. There is a windows tool which can help you to configure the EZL-70, after that you do not need windows to use it off course. But if you really do not want to use windows, read the part in the manual about serial configuration (ATC mode)

Why use the serial comport driver, are you not able to connect directly to the device based on tcpip

According to the manual the EZL-70 can be programmed through the serial port using AT commands, so no windows necessary. After that you just set up a telnet connection to get the data.

The price of the Nport 5110 is completely ridiculous ("low cost"! Yeah right). A full linux computer in the form of a Raspberry Pi would be cheaper (and a whole lot more powerful), even if you count the additional cost of a USB->Serial converter, SD-Card and power supply. And you probably don't even need the USB->Serial converter if you just build a simple 3.3V to 5V interface for the built-in serial port of the Raspberry Pi (a resistor may suffice). On top of that you can run a website on the Raspberry Pi to allow you to control your heating from anywhere on the internet and do lots of other stuff.

The other end is not hardware :) You need to connect to it one way or the other. One way of connecting is with a virtual comport driver. For my current setup I need that driver (under linux)

I want to use it with domotiga to connect to the OTGW and for now domotiga only supports a (direct) serial connection.

The thing is: I want to use domotiga to connect to it and it only supports a serial connection to the OTGW, but maybe I can ask Ron to do a TCP/IP connector as well..

That's not a bad idea at ALL!! I was looking for a good excuse to buy a Raspberry pi! Thanks!

You should ask Ron to implement sockets :-)

Yes that would work nicely with a raspberry π :)

Sorry you lost me.. How could you run remserial on a EZL-70? I want to connect the EZL-70 to the OTGW and receive it on a linux box. How could I use remserial to connect to that network attached serial device? I thought remserial was to create network attached serial devices on linux boxes.
Kind Regards,
Greg.
