That's right. I implied the same when I said it helps in saving time by executing less.

thanks

That's a great suggestions, but as I mentioned mine is a rented property so I didn't want to open up switch board and customize it.

thanks

These questions are hard to answer unless you have tried these configurations yourself, specially in case of batteries many things can go wrong. One thing I can say for sure that tp4056 is safe to be used only with one battery.parallel or series combinations, I have some clues but can never be certain unless I try them.

I won't be able to comment on this as I haven't tried it.

looks good. You can give it a try.

I am not sure. I think connecting low impedance batteries in parallel should be done with care. This might work, you may consider connecting blocking diodes while connecting batteries in parallel for protection.

That's right, Thank you. I will edit the instructable. Thank you again.

Sure,Check out this link- https://www.raspberrypi.org/documentation/usage/we... Look at the end 'time lapse using crontab'

Initially I kept setupEsp8266() in setup(), but I was facing datadrops for long time. I tried a code in which I used to call setupEsp8266() in setup() and call it again when connection was not getting established in updateTemp(). still I had situation where esp8266 will get stuck and will not establish connection.So I did this workaround thing of reseting it every time.Following is the initial code-#include <SoftwareSerial.h>#include <Wire.h>#include <dht.h>#include <Adafruit_BMP085.h>#define DEBUG 0#define dht_pin A0 // defining pin A0 for DHT sensor#define lightSensor A1 // defining pin A1 as input pin for LDR voltage dividerdht DHT;Adafruit_BMP085 bmp;SoftwareSerial esp8266Module(10, 11); ...see more »Initially I kept setupEsp8266() in setup(), but I was facing datadrops for long time.

Thanks

Thanks for the feedback.I will definitely check out the link.

great

Thanks
