## Battery-Powered Smart Devices

Several devices in your smart home run on batteries and will need periodic replacement. Here is what you need to know.

### Yale Smart Locks

**Battery type:** 4x AA alkaline batteries (do not use rechargeable batteries)
**How to tell batteries are low:**
- The Control4 app or touchscreen will display a low battery warning
- The lock keypad may beep or flash red when you lock/unlock
- The lock may respond slowly
**How to replace:**
1. Remove the interior cover of the lock (slide up or unscrew depending on model)
2. Remove the old batteries and insert 4 new AA batteries
3. Replace the cover
4. Test the lock from both the keypad and the Control4 app
**Expected battery life:** 12-18 months with normal use

### Hunter Douglas Motorized Shades

**Battery type:** Varies by model — most use a rechargeable battery pack (Hunter Douglas PowerView battery wand) or a plug-in power adapter
**How to tell batteries are low:**
- Shades move slowly or stop partway
- Shades do not respond to commands
**For rechargeable battery wands:**
1. Remove the battery wand from the shade headrail
2. Charge it using the included USB charger (4-6 hours for full charge)
3. Reinsert the wand
**For non-rechargeable models:** Contact Smart Systems for the correct battery type and replacement procedure.

### After Replacing Batteries

Most devices will reconnect automatically. If a device does not respond after battery replacement, try restarting the Control4 controller to re-establish the connection.
