Just got an email from PEQ – they sell lots of home automation stuff and many are Smartthings compatible. I picked up a few of the lamp/appliance modules from them a few months back and they paired up immediately with my Smartthings hub. IMO, they work a LOT better than my z-wave or Wemo modules. I believe these prices are some of the cheapest I’ve seen, at least for the modules. No minimum for Free Shipping either!
