### ![Red flashing node](https://help.homelyenergy.com/hs-fs/hubfs/Red%20flashing%20node.png?width=200&height=201&name=Red%20flashing%20node.png) **How to change the Homely Temperature Node's battery**

The Homely Temperature Node is powered by a single CR2450R battery (as shown in the image below). CR2450R batteries are inexpensive and are widely available to purchase, either online or in supermarkets and hardware stores. If your battery needs changing just follow the steps below.   
                                        **![Screenshot 2023-10-24 at 11.33.38 (1)](https://help.homelyenergy.com/hs-fs/hubfs/Screenshot%202023-10-24%20at%2011.33.38%20(1).png?width=180&height=167&name=Screenshot%202023-10-24%20at%2011.33.38%20(1).png)**

1. Open the Temperature Node casing. The Node has a slot, beneath the button, highlighted in the picture below, a flat head screwdriver can be used to pry the case apart as displayed.
   
   ![Node v2 Battery Change](https://help.homelyenergy.com/hs-fs/hubfs/Node%20v2%20Battery%20Change.png?width=200&height=195&name=Node%20v2%20Battery%20Change.png)
2. Remove the existing battery from the Node's battery housing.
3. Insert the new battery into the Node battery housing. Please ensure that the "+" symbol on the battery is facing outward.

4. Before sealing the enclosure, press the button on the side of the Node once, the light should flash green.
   
   ![Node green light](https://help.homelyenergy.com/hs-fs/hubfs/Node%20green%20light.png?width=200&height=201&name=Node%20green%20light.png)
   
   a. If the Node light does not flash, please re-insert the battery and try again. The replacement battery may be depleted. 
   
   b. If the Node light flashes red, the replacement battery's charge is low.
