@Peter_Kawa Homey works offline if your sensors work also. @StefanA I wouldn’t bother with a mobile router. It makes things almost impossible to connect/use. ---

Perhaps you can get a good quality router UPS such as [this](https://www.amazon.in/Cuzor-Doorstep-Warranty-Supports-Routers/dp/B0CFB4DSST). They are quite famous and easy to find in India for many reasons 😛 . Most popular models output 12V and you need 5.2V, so you can use a cheap DC-DC buck converter modules based on LM2596 to drop the voltage. Since it is buck converter, the efficiency should ideally by greater 90%. You can also get one with a screen such as [this](https://robu.in/product/dual-display-3a-dc-dc-5-23v-to-0-16-5v-step-down-power-supply-buck-converter-adjustable-lcd-step-down-voltage-regulator/) so that it easier monitor and maintain the output voltage. I know the links point to Indian shops but I am sure you will be able to find same or similar components in your home country. ---

I also use my Homey as my home security. The Homey2023 is on a powerbank with passthrough charging. My ASUS router is on an APC UPS, with a USB 4G-card connected. So on power outage the Homey and the router will continue for a while, and the router will failover to 4G for notifications like water/smoke sensors or burglers. ---

Maybe this could be a solution, if you dare to open up the Homey2023. > **[How to add a UPS to your Raspberry Pi projects (and do it on the cheap)](https://www.zdnet.com/home-and-office/how-to-add-a-ups-to-your-raspberry-pi-projects-and-do-it-on-the-cheap/)** > > Want your Raspberry Pi to carry on running when the power goes out?

Homey’s PCB doesn’t have exposed GPIO pins, so that hat won’t work. ---
