@kevin, I know this comment was two and a half years ago, but I'm wondering how the stress sensor worked out for you? Did you get it integrated with HE? It looks like the product line requires a Sure Action proprietary processor unit.
It was working really well but... during some renovation work someone used the seat as a ladder and broke it causing the Araldited on sensor to no longer get stressed correctly and hence not work. I always meant to replace it with another on the new seat I bought but it didn't happen.
Yeah I can see that processor unit, which seems to be proprietary. How did you integrate the processor to HE? Wonder if it supports a simple alarm NC/NO circuit?
