The weather station is mounted outside, but the work is still not over. I’m having issues maintaining power to the station. I am using an external battery with a solar cell on it to charge it. Unfortunately, the weather station pulls more power than the solar panel supplies to the battery. That means, every day or two I have to pull the battery inside to charge it. I have been working on changing the code to use less power, but none them have worked. The NodeMCU has a deep sleep mode, which required soldering an additional jumper wire between pins. This draws very little power while in this mode, too little for the battery to recognize that something is connected. The battery shuts off before the weather station starts up again, which means no waking up. I haven’t decided what to do yet. I could build my own solar circuit and battery, keep looking for software options, or take this battery apart and hack it’s circuit. We’ll see what the future brings. In the meantime, here are some pictures of it mounted above my garden.
