You could probably change the stylesheet based on a incoming MQTT message. But I personally don’t think it’s worth the hassle. Dimming the light by adjusting colors on a webpage won’t conserve energy (on non-oled display’s) or prolong the lifetime of the device. Unless you are bothered by the light? There is an dark theme available inside node-red. When I’m not around I turn the homescreen off with the help of homeyduino and a wire soldered to the magnetic smart cover sensor. I’ve also made a less intrusive solution by using an ESP32 to emulate a Bluetooth keyboard to lock and unlock the ipad with Homey: > [@Homey ESP32 Bluetooth Keyboard firmware (can lock / unlock iPad remotely) Dev. review needed](https://community.homey.app/t/homey-esp32-bluetooth-keyboard-firmware-can-lock-unlock-ipad-remotely-dev-review-needed/20568): > > I’ve had several request how I unlock and lock my iPad dashboard remotely. I used an old Pad2 that needed an new connector, so when I opened the iPad, I directly soldered a wire to the smart cover magnetic hall sensor to unlock. But opening an iPad is a real pain, and there are better wireless non-intrusive solutions. One solution is to emulate an Bluetooth keyboard and send lock and unlock key shortcuts to it. I’ve written an firmware for a cheap ESP32 module, no need for solde… Sadly this wont work with my old iPad2. It needs to support Bluetooth BLE to work. --- _[View the full topic](https://community.homey.app/t/node-red-a-widget-based-dashboard-working-with-homey-trough-mqtt/18798)._
