Hi I hope I've got the right message board for this issue. I look after my elderly dad who has bad memory problems. I've noticed a few burnt spoons and pans recently and it really worries me that he is leaving the electric cooker on and wandering off. I've left a huge note on the wall above the cooker but I've also read about heat detectors like Tekview Envirotxt that send a text and gadgets that turn the cooker off after a while like Unicook Airis. The problem with my dad and the Envirotext is that he unplugs everything which is good in one way but not in this case! The Envirotxt product is supposed to detect changes in temperature but seems to be more used if there is a power cut than sudden heat rise. He does have a good smoke alarm which I test every time. He doesn't use the cooker for much just quick easy cooking and also uses the grill but I do use the oven when I go there twice weekly. Has anyone any experience of products they have used around this concern or just any tips on getting the message across about not leaving the cooker when it's switched on? Many thanks for any help.
