great form factor and pretty good wifi range. Lack of included docs, like what goes where and how do I set it up, led to 2 day of searching and trying things out before I found 2 lines in a PDF saying how to access it. Further more, they reference windows apps that you can download from their Chinese website. I had lots of difficulties.It does have lots of different wireless connection options: tcp/udp server to Uart so you can poll it, tcp/udp clients to push from, mqtt, http client with websocket capabilities.I'm afraid that I may have fried my sensor with my earlier bumbling because I haven't been able to successfully communicate with it. Packets go out, none come back.

Purchased to allow an Intellitouch pool computer to talk to the open source nodejs-poolController software. I can now control my pool from my phone!It's installed inside the shielded power center which greatly reduces WiFi range. I'm glad I purchased the external antenna version. I'll by a SMA extension cable to move the antenna outside.Well packaged and works great. A little documentation (even just a URL) would be nice, but a web search finds it easy enough.I have already recommended it to others.

Ordered this as a data logger / remote interface for my solar system. The transceiver looks very professional with all connections clearly labeled. The kit includes a mounting bracket, a DIN rail adapter, a WiFi antenna, and an RS485 breakout cable with a covered button that I presume connects to the 'reload' signal on the RJ45 connector. However, there were zero instructions included with this $25 bit of kit (current price on Amazon) so I have absolutely no idea how to get it going.The module is labeled "Elfin-EW11A" which lead me to the relevant software, manufacturer web sites, documentation and software. I've not yet gotten the device up and running, but according to the manuals it can function as a WiFi AP, a standard WiFI client (STA mode) or in AP+STA mode as both AP and client. Configuration is via local web page or remotely using the "IOTService" utility. It's even firmware upgradable. The device also supports a 'remote access' mode over the Internet via the IOTBridge service. IOTBridge requires account creation and device registration. I did not do this. Fortunately, this functionality can be disabled via the IOTService utility.All in all I think this will take quite a while to digest all the documentation and be a fun weekend project to get it set up and working.

I haven't had a chance to really get this thing up and running but it does function and seems pretty stable. I need to run some rigorous data transfer tests but the preliminary test show great results. This unit seems to do what it says it will do.

This device calls home to a server in China every 30 seconds. It is a remote management feature that has no option to be disabled. I returned it as I was not confident in the servers security in keeping others out of my device that is connected to my equipment and also my network.

This product won’t work for what I want which is my mistake (I think) but it did come with everything listed and was packed nicely.
