Hello,
I have set up my SolarMax, SkyWeather2, and SmartGarden3, with 2 extenders (hydro and soil indoor, pots and raised bed outdoor). I would like one extender outside where it can be powered by the SolarMax, where I would also like it to power either:
a "12v@5 - 21W" pump and a set of solenoids or several USB pumps
to achieve water-delivery selection as well as pressure enough to feed a drip-line or a set of sprayer nozzles.
I am also unable to keep the AQI sensor from the Weather Station powered on for more than two days. I have a charger, so I can plug it in, then redeploy it, but I would like to try to keep it deployed. I have set up four solar panels in a sort-of-parabola, and have several sensors set in different ares to figure out the solar patterns depending on Location and Facing. I would like to augment power from the SolarMax in addition to what the four panels can provide.
Questions: Do you have a guide for attaching the extender and sensors like that?
Can I plug the SG3 extender into the USB plug on the SolarMax?
I will attach some graphs of solar patterns for all sensors for comparison, and pics of their "locations and situations" later to show more data and give context. I need to garden now while the sun is out. I will take the pics while I'm working and post them later tonight.
Thank you, ~S

What do you mean "AQI sensor from the WeatherStation?".
Are you talking about the WeatherSense AQI Kit?
Yes, you can plug the extender into the SolarMAX2 plug. That's a 5V USB plug. Use a hub or a USB splitter if you have more USB powered devices.

Thank you. I will move the extender outside tonight.  WeatherSense AQI Kit: Yes, that's the one. I assume that I can bypass the solar charging circuits and just plug the board into the SolarMax, but is there a way to augment the solar charging circuits in the AQI Sensor with the SolarMax, so that I don't tax the SolarMax's battery? Thank you, ~S

Well, there probably is a way to combine the two by using low forward voltage diodes, but the SolarMAX2 battery won't even feel the AQI load so I wouldn't suggest doing it.

Perfect. That's good to know. I will rework my schematics to power AQI using the SolarMAX. I'm thinking that I will power the SkyCam Remote with it as well. It looks like Aftershock and the Lightning Detector are getting enough juice, and I have all three in different places and facings to get a view of the solar patterns from different places in my yard. I will shuffle them to see if it works before I change the schematics though, and report back.
