Main Help Screen
It's a good idea to select "Run Compatibility Tests" to check if this device has the features to operate your Sunflower2.
If it does, go ahead and select "Scan for Sunflower2" to look for a Sunflower2. The Sunflower2 has to be under good sunlight in order that your device can find it.
If the Sunflower2 is not under good sunlight, you may have to press the button on the Sunflower2 marked "ATN" for 3s to get its attention.
Scan Sunflower2 Screen
Press "Start Scanning" to scan for a Sunflower2. How long it takes to find a Sunflower2 depends on how many Bluetooth devices there are around you. If there are not many, it should not take too long to find.
If it is not finding any and you are near a Sunflower2, the Sunflower2 may not have enough sun. Press the button on the Sunflower2 marked "ATN" for 3 seconds to get its attention.
When it finds a new Sunflower2, the Sunflower2 serial number will be displayed along with state symbols on the right.
The following are the state symbols and their definitions:
|❓||Detected a Sunflower2. Waiting for state information.|
|🆕||Sunflower2 has not been configured|
|🆓||Sunflower2 is idle|
|Ⱦ||Sunflower2 internal clock is off by more than 1 minute|
|✔||Sunflower2 is configured|
|✔✔||Sunflower2 is configured and operating normally|
|😴||Sunflower2 is in the process of waking up|
|🔄||Mirror motor stuck - trying to free itself|
|☀||All targets deleted - Mirror is facing the sun|
|⏯||Mirror is moving to a specified angle|
|❗||Verifying mirror motors|
Selecting the Sunflower2 will take you to the next step.
After the Sunflower2 has been configured, whatever name you gave it will show up when found in place of its serial number.
Sunflower2 Orientation Configure Screen
Change Sunflower2 Location
You are ready to program the Sunflower2 with information on
▪ Sunflower2 GPS location
▪ target direction relative to the mirror orientation
▪ mirror orientation relative to the sun
If you select Continue, you will be brought to the next step after your device successfully connects with the Sunflower2
Step 1: Measure Mirror Orientation
In this step, place your device as prescribed by the instruction. The orientation of your device on the mirror is important. It measures the orientation of the mirror and establishes a direction reference. Observe the drawing in the intstruction carefully.
If you select Continue, one of two things can happen depending on whether the current mirror orientation can be used.
▪ If usable, you will be able to proceed to next step
▪ Otherwise, you will be prompted to request mirror to move
If the mirror needs to move to change its orientation, you will have to select Change Sunflower2 Location to get back into the process.
Step 2: Acquire Target
In this step, take a picture of the target. This establishes the direction of the target in relation to the mirror orientation
Step 3: Get Sun's direction
In this step, take a picture of the shadow cast by your head. This establishes the mirror orientation relative to the sun.
Step 4: Re-measure Mirror Orientation
The relative angle among the target direction, the mirror orientation, and the sun's direction are calculated base on measurement taken from your device's gyroscope. The gyroscope may or may not be completely reliable. So by re-measuring the mirror orientation, it compares against the first measurement for deviation. So one of two things can happen depending on whether the deviation is acceptable or not.
▪ If acceptable, you will be able to proceed to Name Target
▪ Otherwise, you will be brought back to Step 1
Give a name to your target. This establishes your first target. After you select Confirm, your device will connect with the Sunflower2 start to program it with the measurments that you have established.
Target List Screen
These are the list of targets you have defined. Next to the target names are target attributes. The following are target attribute descriptions.
|☀||This target is currently where the sunlight is being targeted|
|⚓||This is the target that you have locked in as the Anchor Target.|
You can only train the Sunflower2 using the anchor target as reference. Since the anchor target is the reference for training, it is important to remember exactly where the sun strikes the target when it is locked as the anchor target. You need to take a picture so that you can refer to it later during training.
If you deleted the anchor target, your Sunflower2 still remains trained. However when you lock in a new anchor target and start new training, your Sunflower2 old training is lost and training starts anew.
It is a good idea to add another target as an operating target instead of the anchor target. In this way, you can adjust the non-anchor target to a better position while continuing to train the Sunflower2 with the anchor target. This other target could be pointing at the same place as the anchor target if you wish.

This process allows you to adjust the mirror to beam the sunlight to an exact spot. It offers two modes of adjusting the mirror. Selecting the Mode button toggles between the two modes.
This is the default mirror adjustment mode. At this point, the Sunflower2 has some idea of its orientation and direction. So it knows more or less what left, right, up and down means. By selecting a direction button, the Sunflower2 moves in the direction selected by the number of degrees you specified. This mode is good for coarse adjustments.
This mode directly controls the spin and tilt motors. It dictates exactly how many degrees the mirror should spin or tilt. It may not be immediately obvious to you how the reflection moves when the mirror spins or tilts. So in this mode, you have to go by trial and error. However, this mode is appropriate for fine adjustments.
Where no Anchor Target exists yet, the target you are adjusting will be locked in as the Anchor Target. So if you do not want this target to be the Anchor Target, do not adjust this target yet.
Otherwise, if there exists an Anchor target, this target is a regular target and is adjusted as such.
After you have locked in the Anchor Target for the Sunflower2, it uses that anchor target as training reference. So every time it reflects the sunlight off the reference and you adjust it back to that reference, it is a training point. To do this process efficiently with the least amount of effort, you want to strategically collect the training points.
It is a good strategy to spread out the points at three or four different time of day, one at one other season, and another at another season. So overall, 5 to 6 well placed training points should be sufficient to fully train the Sunflower2. And it should remain trained until the Sunflower2 is physically moved to a different position or orientation.
The Sunflower2 has an inherent inaccuracy of 2 deg or so. So certain amount of drift from the target has to be expected even after it is well trained.
