I’ve got Tuya set up to manage a heated towel rail in my bathroom. Whilst I’ve got no issue getting it to switch on when needed, if I choose duration 60 minutes for example, it does not switch off after 60 minutes. It will stay on indefinitely or will be superseded by the following mornings command to switch on. I’m unable to determine what the 4 different modes mean eg Free, Eco, Boost and Program. None of them seem to enable the automation to switch off the towel rail. Does anyone know how to ensure a device switches off after the required duration or know what the difference is between the various modes? Thanks
