Yes I have multimeter currently it show 4.01 volt in multimeter
Sir is there any firmware updates for this esp01
3.6v MAX is the limit for ESP8266 (Chip)… that is getting fairly low on a LiPo… but the risk…

There may be … but totally unnecessary for your needs.
Google for some ESP8266 powering options… like shown here…

Espressif CEO told me 5V and I have run some of my decent ESP’s at 5V’s for months without any problems.
I think below 4V has a reasonable chance of working.

@dilkhush A little more Googling and I have read that some people report as actually running ESP8266 chips directly off of 4.2v LiPo… a bit of a gamble, but the choice is yours. At least it is better then straight 5v from the USB.

I recently picked up a couple of onions at the food bank… not sure how that helps my Blynk projects… but keeps pesky people away 
No pi though… I am celiac, gluten intolerant

If I remember right I powered an esp with an uno and 100 n/f capacitor. To store up for the bulge uses.
