I used the MP3Trigger for this. It's not quite as flexible as an arduino, but well suited to the job. I had to use a relay to make a standard lighted button work with it.

If you look at the TA-1 manual, pages 32-35, it appears that there are two inputs that can accept wired sensors. But, it sounds like some sort of accessory is required to use them. A google search for "text gsm contact closure" turns up a few other devices with inputs. None seem to be widely...

I think you're right about the TA-1. At least that's how I read the description too. The C3 replaces a phone line. So, if you had a device that would call you when something happened, you would just plug it into the C3. The C3 looks like a regular "land line" to any devices connected to it.

The Cross Point Industries Text Alert sounds like exactly what you're looking for. But, I haven't seen much discussion about it and the cost seems way too high. When you include the cost of some sensors, it seems like you could install a basic security system and connect it to the HAI C3 or...

How far is the shed from the house? There are a lot of wireless motion sensors kits for driveway monitoring which might do the job easily at a low cost. As Work2Play said, there are a million options for doing this. It all depends on the features you want and how much you're willing to spend.

As Work2Play mentioned, there are home automation solutions that will work well in this situation. If you were to make a multi-wire branch circuit, you would need to use a 15 amp double-pole breaker for the two circuits to share a neutral. You'd have some research to do if you were to take...

Can you comment on any of the ones that didn't work so we know what to avoid? Thanks
