Tempest #5173 went off line and appears to be dead. Hub is up and connected. Rebooted a couple of times to be sure. Green or blue light as expected. Last warning was battery low at 2.33 volts. We have had a week of cloudy/rainy weather. How can I tell the status of the sensor unit? There are no status lights visible. ---

Hello etroup if you look at the [voltages](https://community.tempest.earth/t/tempest-battery-voltage-range/6120/2) you would already understand that your Tempest is depleted. It won’t start unless it gets a charge I just looked at your station and it really never charged properly since quite some time, I suspect a faulty charge circuit or to much battery drain. If you could get it in direct sunlight for a few hours, there is a chance it comes live again but for sure it won’t last long. Open a support ticket and customer support will help you out. ---

I see the low battery voltage. Left tempest in some sunlight this morning and it seemed to wake up when I reset it and reconnect however I am not seeing any updated data in the application. ---

which is normal, voltage is very low and all power saving modes are on so way less updating data (see link I gave above) ---

I’m facing this same problem. Unit kept going offline at night after a few days of clouds and rain. Finally emailed support once it was offline for a whole day after dropping below 2.33 volts. It came back on the first sunny day and is slowly making its way higher. Waiting for a response from support currently. ---

Have dismounted the Tempest and left it in the most optimal positions possible for recharging. Still stuck at 2.33 or 2.34 volts. Cannot get an adequate charge. I submitted a ticket but have received no response. The Tempest sensor remains unusable after only 57 days. What is the resolution??? ---

Left Tempest in an optimal position (leaning back with panels pointing directly south at Sun) to charge. Still has not come back. ![20200915_191616628_iOS](https://us1.discourse-cdn.com/flex020/uploads/sws/original/2X/0/0af9e2580155d897848cb3cead647de94659b6a9.jpeg) ---

You did leave the switch on, right. In the off position it won’t charge. ---

I am having the exact same problem with my tempest now. It will sit in the sun all day, won’t go over 2.35 volts. It’s now in power saving mode. I wiped down the solar cells with water and a cloth and set it in direct sun. It’s not charging. ---

contact support… you probably need a new tempest sent to you. ---

Wait till I have a chance to get a reply from internal, have asked since you deleted your tempest in November and re added a few days back. ---

Received. Thanks, Eric. Feel free to PM if you wish 👍 ---

I’ve been comparing the original SWS to the Tempest in mobile environments. I’ve since pulled it when the issue arose, and cleaned it and placed it in a fixed location in full sunlight. Still having trouble charging. Thanks for inquiring with the team. 💪 ---

Looks like “Tempest - a - GoGo!” OR Tempest – DON’T Leave Home Without It!
