Receiving Current Cost transmissions via a Basenode
21 February, 2013 - 00:31
Reading over on the WH1080 Weather node thread got me thinking that it may be possible to receive and decode CurrentCost info and do away with the CurrentCost LCD which IMO is simply gathering dust via a jeenode with a 433mhz RFM12B module
The CC Transmitters operate on 433mhz FSK using RFM02 (similar to the RFM12B but Transmit only) and transmit at 6hz intervals depending on the number of sensors attached
I have been informed CC have not disclosed the format so it would need to be reversed engineered
the other solution is to directly interface the CC clamps / Optismart sensors to a modified jeenode and do away with the CC transmitter / receiver
interesting to see if anyone has looked into this?
thanks

Check out Jack's code for the EDF Energy Monitor
https://github.com/JackKelly
It runs on a 433MHz Jeenode fine and reads Currentcost transmissions.

CC decoder
I've got this running on a basenode with 433 RFM12. I'm thinking of adding my WH1080 weather station decoder to this code and have an all in one unit.
I toyed with the idea of switching the RFM12 into OOK mode as documented on Jeelabs but instead I'm adding an AM 433MHz receiver to one of the analog ports instead.

CC and WH1080 update
I was going to try to have the WH decoder and CC decoder on one node but have now gone down the route of using two separate nodes. The WH receiver is running reliably as is the CC but still working on integrating this into the HAH.
I've also got another node monitoring the HE Rf transmissions. It acts as confirmation that the HAH has sent an RF command but also picks up commands sent from the remotes, I'm planning on using that information to update the current state of RF sockets on the HAH i.e. if SWMBO turns on the kitchen TV with the remote rather than the HAH interface or app on the phone then I know ;)
There is now a small team working on integration, updates will hopefully follow soon

Ah I see that is what the URF Rx tab is for :)
Good ol' Brett, 3 steps ahead

URF Tx FTW
Mark indeed this is what URF Rx is for http://www.dbzoo.com/livebox/universalrfrx you must be on the BETA release !
Since writing this up I've not had a good chance to really set this to work. I was hoping others might jump in and have play. Certainly having an upgraded HAHCentral that can receive 433Mhz RF works really well and I did release a new sketch for this in source form so you could play.
