Re: Clas Ohlson energy meter support?

No, probably not that (though that may be useful too for someone looking for turnkey solutions). The useful information meant was behind the links, there's detailed documentation on protocols used by Efergy energy monitors. If the Clas Ohlson Efergy uses the same protocol, someone familiar in progra...

Re: tdtool status / temp.hum sensor values?

Some more progress, the humidity reading seems correct now, temperature somewhat off - when the station shows 0.3, my code shows 0.5, when the station shows 0.4, my code shows 0.7. So perhaps there's e.g. a negative value conversion fencepost error by 0.1 and a divider of 2 needing to be added. fine...

Re: Tellstick duo. Custom firmware ?

Thanks, this is good to know and remember. To clarify, a couple of questions:

- with the pickit reference, are you saying that if the device is bricked, PicKit2 can be used for unbricking?

- is the area 7A00-7FFF that where the bootloader resides, which must be avoided?

Re: tdtool status / temp.hum sensor values?

The last three bytes are FF DF 56 (in hex), and last byte is 0x56. Looks like the first tree hex digits of those are the temperature quite simply coded (0xFFD = -0.3 degrees, 0x000 = 0 degrees, 0x001 = 0.1 degrees etc.) Seems to work for all measurements I've made so far, which are in the limited ar...

WH1080 / Clas Ohlson 36-3242 with wind & rain sensors & USB

I've got one of these, and would be nice to get wind & rain readings to the computer directly via radio. http://www.clasohlson.com/uk/Weather-Station/Pr363242000 Anyone have info or pointers to the radio protocol? I've seen some pointers to USB protocol and there's some software for USB interface so...

Re: Tellstick Duo - Prologue temperature sensor

The thread linked to below might help, I have a sensor with the same symptoms and I am now able to see humidity & temperature with modified firmware & telldus-core.

Re: Tellstick duo. Custom firmware ?

Have you considered an area for firmware development, protocol code development and the like? Maybe named "Development"? I suspect talking much bit & hex codes & encoding talk on Hardware forum might make the forum a bit too far out for people interested in just the end result. I know there's http:/...

Re: tdtool status / temp.hum sensor values?

A version of the patch to firmware is at http://developer.telldus.com/ticket/90#comment:3 - heavily experimental so should not be really used by end users (and requires also a modified telldus-core to actually work), only for educational purposes at the moment. Basically what seems to be different i...

Re: WH1080 / Clas Ohlson 36-3242 with wind & rain sensors &

Mainly because of freer placing of the WH1080 and not having to have a USB cable - I'd like to place the WH1080 so that it wouldn't have to be near to a computer/server and/or to have an ugly cable running to a computer/server.

Re: tdtool status / temp.hum sensor values?

By the way, in addition to the temp&humidity sensor I was aiming for, I seem to be getting data from some other sensor(s?) with my code - could be my code mistakenly inteprets Oregon data, as with this code I don't see any Oregon values which I occasionally saw with previous code. hex data:9D4F8FF6...

Car locks / keys?

Anyone happen to have investigated receiving car key (remote lock open/close) codes with the duo? Some time ago, I noticed that my car key happened to output a signal which changed the state of a remote control socket. From googling, frequency seems to be the same. I'm thinking of something like tur...

Re: Car locks / keys?

Modifying tellstick (Duo) firmware isn't a problem now that the code is available. Yes, I'm aware of the rotations, but at least in one protocol description I read, the key was sending also a fixed id string, so it could perhaps be possible to recognize a specific car key even not handling the rotat...
