johnnyt Posted November 10, 2012 Posted November 10, 2012 Just wanted to let folks know I've had good success using the Autelis RS232-to-ISY product. I'm working on moving my 1-wire temp/humidity sensor solution from HomeSeer and bought the Autelis device with a splitter cable that allows me to keep HomeSeer running for the stuff I haven't migrated while I chip away over time at setting up the ISY variables and programs I need. Although there were a couple of firmware glitches in the beginning, response was very quick and Autelis even added some functions I needed, also very quickly. FWIW, my 1-wire solution is based on Midon Design products (http://www.MidonDesign.com). They package 1-wire temp and humidity sensors on a small PCB (called the MD3020E) that one connects up to a sensor reader (called the Temp08), which does the polling and outputs results to an RS232 com port. I have about 8 sensors in use and use them to control bathroom fans, furnace fan, HRV, humidifier, duct dampers, roof cable and car block heater in winter, etc. The Autelis bridge allows me to populates ISY state variables and has been rock solid (like ISY). Am about half way there in my migration. When I'm done I may get another one to migrate my RCS TR40 thermostat over to ISY. It's great to be able to run the 2 systems in parallel and be able to work on it in manageable chunks of time.
propman07 Posted July 22, 2013 Posted July 22, 2013 Hi- I ran across your message, and I was curious as to how you were progressing with the conversion. I have been looking into a way to get temperature data (i.e. room temp) into the ISY so that I could send out notifications/updates on when rooms get too hot/cold when I'm at work. Thanks.

The autilus device looks like it would work fine. But for a lot less money a CAI webcontrol can do the same thing.
johnnyt Posted July 22, 2013 Author Posted July 22, 2013 Yes, I've completed the migration of all my temp/humidity sensor data into ISY state variables and everything has been working like a charm. Some of the stuff I do that's temp/humidity triggered can be found here viewtopic.php?f=48&t=10174 I never did migrate my (RS485 wired) RCS TR40 thermostat because the comms died on it.
johnnyt Posted July 22, 2013 Author Posted July 22, 2013 The autilus device looks like it would work fine. But for a lot less money a CAI webcontrol can do the same thing. The one humidity sensor per CAI board - unless that's changed - would mean, in my case, 8 boards...

The one humidity sensor per CAI board - unless that's changed - would mean, in my case, 8 boards... Is there a 1-wire humidity sensor? I know CAI has expanded what 1-wire devices you can attach to the 1-wire bus. But I have never seen a 1-wire humidity sensor and if there is, I don't know if it can be added to the 1-wire bus. I do know of analog humidity sensors, which could attach to the 3 analog ports on the CAI board.
johnnyt Posted July 22, 2013 Author Posted July 22, 2013 Is there a 1-wire humidity sensor? I think the humidity sensor at the heart of my solution is a 1-wire humidity sensor but I'm frankly not sure - it could be that the "boards" I bought convert the data to go over a 1-wire bus. FWIW, according to the Midon Design web site, it uses the "HIH4021 sealed humidity sensor that is software equivalent to the Dallas/Maxim DS1910." I think it's made by Honeywell. I know that this sensor is better at handling the more extreme conditions you see outdoors where I live (-30C to +40C) then the ones from Dallas/Maxim they used when I bought in 12 yrs ago. In the early years I was replacing my outdoor sensors every 1-2 years. Since moving to the HIH4021 ~5 yrs ago I haven't yet needed to replace one. Edit: found this note on Midon Design website: Honeywell HIH-4021 Sealed Humidity SensorNOTE: this ... requires additional circuitry to function as a 1-Wire sensor.

I was responding to propman07 who only mentioned temp in his post. You are using the RS-232 format, not 1-wire correct?

io_guy Posted July 23, 2013 Posted July 23, 2013 Been using this for months now without any issues, much more stable than my CAI: viewtopic.php?f=95&t=11461 I use a Raspberry Pi with 1-wire controller installed (RPI2) and OWLink.
Teken Posted December 19, 2013 Posted December 19, 2013 Johnnyt, I know this post is quite old but I would really appreciate it if you could document in detail what had to be done to accomplish this end goal. Screen captures and photo's of the actual install would be really great to see. I have been waiting a very long time for the ISY to support my GEM for temperature, pulse, and current / amps. Having an additional 32 channels for temperature / humidity using the above device would be great. Teken . . .
autelis Posted December 19, 2013 Posted December 19, 2013 You can definitely get all your GEM data into ISY variables by connecting our RS232 interface to one of the RS232 ports on your GEM and we will assist you with configuration as necessary. Please start a new topic if you would like to request an example configuration. Thanks
