Thanks for comments .... bit undecided which way to.go .... SmartFire or a simple PID controller. I do prefer a modulating controller approach, just need to get my head around it being 10x the price.
On the ‘Lid open’ function, I agree it’s a good feature, it’s just that a 10min delay to restart control does not makes sense ... maybe there should be a simple ‘re-engage’ option on the App. No change to set temp or other options, just a way to tell controller lid is closed - get going again.
Are there any other modulating controllers to consider, I did come across a Raspberry Pi variant, but that it quite complex to build.
