Hi @berkseo. Thanks for the suggestion, but could you describe in more detail? As for my TODO list, there is already a task to add 485 interface to the gateway. My latest device "xRoom" have this interface. ps/ Where have you gone? I have been working on "xRoom" shield. A small announce: Do you remember the discussion about multinode? So, it will be available soon))

@yoonie said: For the pro mini version, should i create another Openhardware project, or should i put it here, in the already existing project? Might be better to create a new project as they uses a different set of design files.

The final version of the boards contains few notable improvements Removed the PCB under the ESP8266 antenna. The previous design had PCB + Ground Plane, which resulted in VERY low reception. It worked just few meters away from the router. Removed the Temperature Probe - On the one hand - it does not really measure real temperature, on the other hand it populates the Single Analog port, and makes it unavailable for other usages Added place for an optional LDR (in case the Analog port is not used - one could add an LDR for added value) The connection between GPIO 16 and RST (Deep Sleep) is not bridged via a 0603 0ohm resistor (jumper). Depending on application it may be enabled or not Added a Power 5V line. That is - controlled via a SOT232 mosfet and one GPIO. This way you can connect power hungry modules and then turn them on or off. There are small mosfets rated ~ 2-3 amps for couple of cents. The big 12mhz crystal for the CH340G was replaced by a small patch ceramic oscillator to save space Added an additional mounting hole Added additional test pads for the unused GPIOs Added one Diode in series with the power to the WS2812B LED. It turned out, when powered directly via a USB Battery bank, the voltage can be 5.30-5.40v. And apparently WS2812B, does not light if VIN is > 5.15V. So putting a generic small Diode would drop 0.3-0.4V Here is how the latest design looks like

Still, there seems to be 'someting rotten in the state of Network' where my LAN is concerned. Although the Arduino serial monitor says: 13:03:55.821 -> connected with XXX, channel 6 13:03:55.868 -> ip:192.168.178.4,mask:255.255.255.0,gw:192.168.178.1 13:03:55.915 -> ip:192.168.178.4,mask:255.255.255.0,gw:192.168.178.1 13:04:04.826 -> pm open,type:2 0 when I ping the IP-address I get: Pinging 192.168.178.4 with 32 bytes of data: Request timed out. Request timed out. Request timed out. Request timed out. Ping statistics for 192.168.178.4: Packets: Sent = 4, Received = 0, Lost = 4 (100% loss), When I use the tool 'Wireless Network Watcher' I do see that a device is connected at 192.168.178.4 with the correct MAC address. However, when I look at the management page of my FritzBox 7490 modem/router no device is mentioned at 192.168.178.4. I remain at a loss here.

I think I found the problem. I think it misbehaved because of an illegal character in the "HOSTNAME". Changed the hostname yesterday and It was still alive this morning even if I have not pinged it.

Advantage of this sensor is fast and easy installing by the non qualified personal. The sensor is designed for large agriculture facility with many greenhouses where is needed to be controlled temperature and humidity, the atmospheric pressure is for control the motor of air inlet and outlet. With help of the sensor installed outside the greenhouse provide information about positive/negative pressure inside the greenhouse. Finlay the software read accurate temp/humid value of the Si7021, and only atmospheric pressure of BMP180, the temperature sensor inside the BMP180 is used only by the sensor itself to provide accurate atmospheric pressure measurements. The sensor can be used also for home automation, and drone applications where is needed correction of the UAV barometric sensor compared to the ground barometric sensor, also humidity measurement can help the pilot to calculate more accurate flying time.
