To solve the Teplo Oasis Monitoring Device puzzle, fully charge each of the three machines with Normal Attacks while its needle stays inside the highlighted range. This hidden puzzle in Genshin Impact 7.2 becomes available after you complete Mitya's introductory Teplo Oasis World Quest. The reward is a Precious Chest, but hitting every machine once will not unlock it. You need to adjust your attack rhythm to each device's target band and finish its circular charge indicator.
How to unlock and find the Monitoring Devices
Complete Mitya's introductory quest
If you have not started Mitya's local storyline, find him sitting at a table in the gazebo near the stone bridge by the winery. Speak with him to begin the opening chapter of his Teplo Oasis Meeting Point Chronicles.
Follow the quest through the damaged orchard and nearby farmland. Its main practical objectives are:
- Clear the fallen rock formations using Mitya's Elemental Skill. Move close to the debris while the skill is active to break it.
- Activate the two soil-monitoring devices introduced during the quest.
- Return to Mitya and finish the closing conversation.
The two quest devices are separate from the three machines used for this chest puzzle. Completing the introductory pair does not complete the hidden challenge. If you have already finished the quest, head straight to the northern waypoint route below.
Head east from the northern residence
The extra devices are around the crossroads beside the fields in northern Teplo Oasis. Use these landmarks to reach them:
- Travel to the northern section of Teplo Oasis.
- Locate the residence near the local Teleport Waypoint.
- Head east from the residence toward the crossroads beside the farmland.
- Look around that area for the newly available group of three Monitoring Devices.

How the Monitoring Device gauges work
Each machine displays a horizontal gauge with a moving needle, a highlighted target band, and a circular progress indicator. A Normal Attack pushes the needle to the right. Between hits, it gradually drifts left.
The highlighted band determines where you need to hold the needle. The circle fills while the needle is within that band, so your task is to control its position long enough to finish charging the device.
Match your attack rhythm to the target
Check the highlighted section before attacking. Two machines use a middle target, while the remaining machine needs a reading near the far-right end.
| Device group | Count | Target position | Attack rhythm |
|---|---|---|---|
| Middle-range devices | Two | Around the center of the gauge | Spaced Normal Attacks with pauses |
| Near-maximum device | One | Close to the far-right end | Frequent Normal Attacks |
You can activate the devices in any order. Identify them by their target bands, not by an assumed first, second, or third position around the crossroads.
How to activate all three devices
Charge the two middle-range devices
Start with either machine whose highlighted band sits around the center of its gauge. Use your Normal Attack input for controlled hits, watching the needle between attacks.
- Hit the device to push its needle right.
- Pause and let the needle move into the highlighted middle section.
- Watch it drift toward the left edge of that section.
- Strike again as it approaches the edge to push it back toward the target.
- Continue making these corrections until the circular indicator is completely full.
Avoid long strings of uninterrupted attacks on these two machines. Repeated hits can push the needle past the target's right edge, leaving you waiting for it to drift back. If that happens, stop attacking until the reading returns to the highlighted section.
Once the first middle-range machine is fully activated, use the same approach on the other one. Watch its gauge directly instead of trying to repeat a fixed number of hits.
Charge the near-maximum device
The machine with the far-right target needs a more aggressive rhythm. Stand close enough for your attacks to connect, then keep landing Normal Attacks to maintain a high reading.
Pausing as long as you did for the middle-range devices lets this needle fall away from its target. Keep attacking frequently and watch the circular indicator until it finishes filling.
The target band remains your reference. The goal is to maintain the reading within that section, not simply to land as many hits as possible.
Precious Chest rewards and completion checks
A Precious Chest appears nearby after all three devices are fully activated. Open it to collect Primogems, Cryo Sigils, and other exploration rewards.
The chest may also contain a Residual Incense Guide, a collectible associated with exploration in Novokitezhgrad and Teplo Oasis. This is possible loot, not a guaranteed reward.

What to check if the chest is missing
Inspect each machine's circular charge indicator. A needle pushed to the right is not proof that a device has finished activating. The horizontal gauge shows the current reading; the completed circle confirms that enough charge has accumulated in the correct range.
Check all three circles, including both middle-range devices. Finish charging whichever machine is incomplete, then look nearby for the chest.
