Wie lang hält denn eine CR2032 bei nem 24/7 bepowerten ESP (Auch wenn im Deep Sleep)?

Laut Internet braucht der ESP-01 im deep sleep 22uA.

This looks great!

Translating the description (google translate + manual cleanup) for us monolingual americans:

I've been looking for a DIY dash button for my FHEM SmartHome system for a long time. Here on Thingiverse I found this [ESP8266 IoT Wifi] button (https://www.thingiverse.com/thing:2803769).

I really liked the design of the case as well as the possibility to operate it via MQTT.

Since I still had ESP-01 and CR2032 at home, I got down to work.

components:

  • ESP-01
  • CR2032
  • Button 6x6x8
  • double-sided board
  • silver wire

First, I broke off a rectangle of the board (about 65mm x 22mm), then rounded the corners so it fits into the case. I placed the button so that it sits under the movable end of the lid. For me it is about 16mm from the head of the inner wall. Since I did not have a holder for the CR2032 battery, I built it from a strap made of silver wire.

The circuit is quite simple and should be easy to solder even if you don't have much experience.

Before the ESP-01 is soldered it has to be programmed. Be sure to test the ESP-01 before installation. After soldering, it can not be reprogrammed (or only with great effort). Next, remove the red power LED, then the ESP-01 can be wired. It may help to use a piece of perfboard between the spacers and the board installed (as show in the photos). This brings me to 4mm distance between the ESP-01 and the motherboard.

Have fun
