Anyone used a URC-8800 Nevo WiFi Bridge ?

Vicky,

At least my "box" has a built-in IR-blaster, capable of sending IR over reasonably large distances, located on the side opposite of the jacks.

Another source for stick-on emitters is smarthome.com

Not hard for you, but VERY hard for me. But I really need to do something hard. I haven't learned anything in a long time, and it gets really boring.....

Overcoming inertia and self directing myself is not my strength.

Thank you for the code. I copied it down to my work area so I won't have to search for it.
That is the right approach! I wish you good luck! Very Happy

Well this is the ultimate in "tax evasion", meaning that I have been doing this when I am sitting here at my computer trying to get my taxes ready for the mail.

I now have my phone friendly HexByte Calulator.

Now back to the Nevo Bridge and the Nevo C2 remote. But only after the taxes are in the mail!

Congratiolation!

But it is a litte different from what I envisioned.

How does it work? I can get digits to appear in the top box by clicking the keypad buttons, but nothing else seems to happen.

It is pretty close to the tool in IRScrutinizer, except I needed the controls to make it easy to enter hex on a touch device. No flipping back and forth between the various keyboards for alpha and numbers.

Or do you share my DH's opinion of the color scheme, he said "nice use of color" accompanied by a big eyeroll.

followed by a choking noise.

Code: Select all

  
" = "    makes it calculate
"Clear" makes it clear the Accumulator
"BS"    makes it backspace

EDIT: Oh I see, on some devices this doesn't show all the controls. I guess I need to edit the style sheet to get this to show all the controls on the same page. I can do that now that it is actually working and doing the calculations!

If it is accumulating that is a great sign. I had trouble getting this thing to work on the various browsers. It first worked in firefox, then after more tweaking chrome, then more tweaking ie, then more tweaking ie on windows 10, then more tweaking, Edge and iphone.

I've wanted something like this for years. Barf has it covered on the PC, but I need it on my phone and tablet which is where I do 60% of my computing.

Ah, the = button, I never thought of trying that. I was looking for an ENTER button.

Hi Vicky. Cute tool that would be handy on a phone. I have one suggestion for the user interface that would have completely avoided Rob's question. You could recalculate and re-display the results every time a number is entered via the keypad. The user might be shown some intermediate results that aren't interesting, but the numbers displayed in the results fields would always reflect the number currently entered in the input field. An example of this style of processing is the calculator in Windows 10 when it is in the "conversion" mode. To see this in action, bring up the calculator, at the top left, click on the 3 horizontal bars (at the top left), choose something like "Temperature" under the "Converter" category. You will see that the converter has already entered "0" and converted it and as you type it continually converts whatever is shown. It's pretty convenient and should be a simple change to your tool if you like it.

Thanks Phil, yes, that will be easy to implement.

The thing that really needs changing is the look. It looks different on every, every browser, some okay, some really bad!

Back to the original topic.

Has anyone done any attempts of "hacking" the protocol of the Nevo box?

I just opened mine. It contains two big ICs, which I could not identify, probably ASICs of some sort. One of those probably dedicated to the WLAN communication. I can make photos if someone wants it.

The IR sending power is quite OK. There are three sending IR-LEDs, and they appear to have 3R3 resistor next to it, meaning pretty much sending current). The same MAC address is used both for WLAN and the wired LAN, which probably means the the wired connection is not really meant to be used.

To take the WLAN "out of the equation", I configured it as "pure access point". I then fired up the package sniffer wireshark, and fired some commands using the Nevo application on an Android tablet.

Unfortunately, I could not make sense of the captured packages. It definitely does not use well-known IRv4, but uses IPv6 (for some of the packets). If there are packages that wireshark misses, or if it is there, possibly encrypted, possibly masqueraded in innocent looking packages is unclear to me.

Sorry.

Barf, can you upload the capture file? I would like to take a look.

A bit off topic, but I have been playing around a lot with the Broadlink RM Pro.
https://www.amazon.com/Broadlink-Pro-Wi ... rds=rm+pro

It has Android Tasker supporting it, and a nice Python lib here:
https://github.com/mjg59/python-broadlink

The Python lib provides very simple control - I have actually just been learning functions I need, but I am sure y'all could do better

I have personally been moving more of my system to IP-based control, and using this guy to fill in the gaps.

Not using it as my primary remote yet, but here is the remote I made in Tasker:

One of the reasons I (and everyone) hates touchscreen remotes it you have to look at them, but with gestures on top of buttons it isn't so bad. Tap anywhere, pause/play. Swipe up/down volume, left/right 30 seconds skip..

Sure. (EDIT: removed file.)The sender (android tablet) is 192.168.1.127 (resolves as "tablets"), the nevo is 192.168.1.9 (resolves as "nevo"). But my gutfeeling is that wireshark somehow has not captured some important packages.

@xnappo:
(This would deserve its own thread.) Interesting. The key question is of course if there is a published API. Do you know it the Github project is based upon official API documentation or reverse engineering?

@barf started a new thread here and answered your question.
