Hello!
I got stuck with showing battery level in openHAB and I didnt find any topic in forum so I ask myself:
does somebody have example how to show battery level in openHAB (through MQTT gateway)?
Sketch already sending battery level with **gw.sendBatteryLevel(batteryPcnt) ** statement and I see percent in gateway.

Sorry, the correct new Ethernet module type is W5500.
Hi,
I had similar issue. I found that problem was W5100. It just turned to brick when it runs long time as server. And I have seen that many times.
Upload basic ethernet sketch and check that Ethernet module is still working. I found that mine was not working at all.
My workaround was to use W5300 what is much better. Runs colder and is able to share bus.
@Anticimex Lots of nice features are listed in announcement!
Where I can find documentation for v2?
I'd like to try MQTT gateway on W5500 chip and I'd like to test sensors connected directly to gateway but I have no clue how to start.

Hi,
I use usually Arduino Pro Mini board (if possible then 8MHz and 3,3V version) and step-up module for battery.
I use small electricity junction boxes for casing because its so cheap.
If you have designer skills, then you can design your own cases and then use 3D printer to make design real.

Hello!
Is there any thoughts or ideas using CC3000 based WiFi module in Ethernet or MQTT gateway?

Hi John!
Can You tell, is it possible to show battery level and sketch name and version in PiDome? How to describe this information under custom device?
Thanks in advance
Vj
Yep, I already looked too PiDome because it can be used with serial gateway. But using standard MQTT was very appealing.
If not only me have fried w5100 boards then probably they are suitable only using as clients not servers. And they cannot connect to servers too often.

Thanx for your feedback!
I have also 12V power adapter but it is connected to 5V switching regulator (5V linear regulator 7805 got too hot and heatsink took lots of space) and with this 5V I power Nano and ethernet module and for radio is separate 3,3V linear regulator powered from 12V.
Everything is cool exept ethenet module chip and module 3,3V regulator.
I waited a day but no communication between Nano and ethernet module (all lights are blinking) and no ping reply. I also uploaded simple web server sketch but web server also not working.
First step is ordering one cheap w5100 module from China. And also check things with oscilloscope.
Probably I must take a time and test ENC based ethernet module with Mega and softSPI. And if this combination not working or working but not reliable then old good serial port is last resort.
But openHAB will not have serial binding for mysensors what mean that I have to look to another controller or make my own controller.

Hello!
Maybe someone who uses W5100 based Ethernet module in MQTT gateway can tell how hot the chip in ethernet module is?
Mine was (and still is) hot and accordingly to specs this kind of modules will consume typically 185mA (3,3V) in 100M connection what is a lot. But problem is that now gateway is not responding to openHAB and ping dont get answer.
Gateway serial port only shows messages from radio network and no TCP debug information. Module have lights blinking and chip is hot but nothing happens. Is it so that W5100 burnt himself out? It worked continiously few weeks.
But ENC based MQTT I didnt get to work and soft SPI version didnt fit into Nano memory. Probably I will test it with Mega and see if this combination will work. Does someone have ENC based MQTT gateway what is working?
