Oh man, that sucks!! I am not surprised but totally bummed that they discontinued the ThingShield. Someone said there was not high demand and that they made the shields by hand. It was a perfect storm, plus Samsung now has their way with things…
Here is a link to some hope for the future, no promises!
We could theoretically be able to do without the shield, but it’s an uphill battle. We can do a wifi, LAN, zigbee or zwave module with the arduino or raspberry pi. The basic concept is that the arduino reads the serial communication from the Concord, send the appropriate message to the ST cloud, and then ST will set statuses, and send back commands. The concepts here can be reproduced but again, it is an uphill battle.
I’ll see what I can find over the next few days.
