Omar, it's great that he goes directly controls the power of my new heaters. But astrophotographers ask us to automate everything. Echo! It would be important to calculate the viewpoint. That's the temperature where you condenses on the optics. Echo! And then, automatically control the power for the new heaters, avoiding new problems all night long. We have to build a compact device that is easy to install on any telescope. Echo! Two! Echo is this compact and lightweight device that we designed to automate control of new heaters connected to the Eagle. Echo can be easily installed on any telescope, since it connects to a stand-up financial. It's an external device, separate from the Eagle because it has to measure environmental data, like temperature, humidity and pressure, with its integrated sensors. You can connect up to three external temperature sensors to the Echo, and on the other side, you insert the temperature probe between the telescope and the new heater band you want to automatically control. By comparing probe readings with data, coming from its integrated sensors, Echo calculates the point and automatically regulates power of new heaters connected to the Eagle. Echo is a simple to use plug and play device. Echo comes with a star-the-USBC type port, connected to the Eagle with a provided USB cable, and press Echo button in the Eagle Manager. Now, Echo shows our temperature, humidity and pressure. If the Echo detects that a new heater is associated with a temperature probe, it automatically takes control of new heaters power by keeping your optics at a temperature just above the dew point, preventing dew from condensing on your telescope. Echo comes with more advanced features, like smart control of temperature probes, to automatically detect uncalibrated or wrongly connected temperature probes. Dark mode to disable the Echo LED lights, and ask a driver that allows you to use it with third-party software, or even with standard Windows computers. All of these, in the compact and plug and play environmental computerized controller.
