Just watched your video Brian and want to say I enjoy your YouTube channel... this boil controller is something of interest to me. I just bought 2 kettles from Grounded Brewing Technologies and was looking at options for electrifying one of them for a HLT. Right now I either BIAB or use a my BK as a HLT with cooler mash tun / RIMS and drain runnings into buckets until the BK is available... but for not that much I can potentially make a e-HLT, use my cooler / RIMS for mash, then direct fire the boil... it's not a sexy setup, but seems like it can work with this inexpensive controller.
