Comment on Hacking Eaton HomeHeartbeat Part 8: Sensors by bryan

Hi Steve,
How are you reading the events from the HHB? Do you just enable the debug log and read status from that? Also, are you able to write data back to the HHB such as to communicate with the Keyfob? Just curious on how far you got with it. I have a debian linux system that I am running for my home automation system, but have not integrated my HHB into it yet.

Paul,

Im currently using a Raspberry Pi to talk to my HHB. It acts as a bridge device between my custom home automation system and other devices. More of a proof of concept at this point but it is functional.

In my case, software running on the rPi listens to the HHB, 1-wire, and X10 wireless and re-transmits events via MQTT. Another application listens for MQTT events and forwards them to Cosm for graphing. You could do something similar to send SMS text or email.

Raspberry pi is a nice little embedded Linux board which costs $30. They are hard to find right now due to demand.

Hi Steve,
Have you had any luck with getting HHB online or at least sending text messages? I have one and looking for ways to get text or email notifications out from the HHB.
Thanking you in advance.

Comment on Robust 1-Wire Support for Arduino via EDS HA7S by Mike

Did you ever get to posting your arduino code with using the HA7S? I am looking to operate 21 1-wire temperature probes running on an arduino or if this chip works well enough directly to a logomatic v2 from sparkfun.

Exchanged a couple of email messages with Allison about this. It’s an amazing price, especially if you’re looking for volume purchase.

Comment on Update on py-openzwave by steve

Andrei,

py-openzwave hasn’t gotten much attentention lately, glad to hear that you’re playing with it. Since the application really hasn’t been worked on in the last year it is probably desperately in need of a refresh and synchronization with the main openzwave project.

I’ve always performed node removal using the native hardware support rather than programmatically; as far as I know that capability doesn’t even exist. I don’t often remove devices. I’d suggest checking with the main openzwave project to see if this is a supported capability.
