# esphome
## Installation
Recommended: [venv](https://docs.python.org/3/library/venv.html).
```shell
# Optional
$ python3 -m venv .venv
$ source .venv/bin/activate
$ pip3 install -r requirements.txt
```
Your PC timezone is important for esphome schedules, as they will use compiler's
timezone when syncing the clock (NTP). Consider changing it to your home TZ:
```
# dpkg-reconfigure tzdata
```
## Compiling
```
$ cp -i secrets.yaml{.sample,}
$ cp -i templates/secrets.yaml{.sample,}
# Edit both secrets.yaml files.
# Optional
$ source .venv/bin/activate
$ ./reflash.sh compile ''
```
## Running
```
# Optional
$ source .venv/bin/activate
$ ./reflash.sh
```
or
```
# Optional
$ source .venv/bin/activate
$ esphome run file.yaml
```
Look up list of runnable files inside `reflash.sh` script.
## Hardware: heating
### Photoresistor
Schematics:
1. A0 -> 10K Ohm -> GND
2. A0 -> Photoresistor -> 3V3
Assembly:
1. Put isolation band on the legs
2. Solder legs to dupont wire (the other end has to be male)
3. Bath it in the insulation varnish
4. Think the isolation band with a fan
Color coding for RJ45 cable:
- orange: furnace
- blue: floor
5528 photoresistor: 8-20K resistance by brightness, up to 1 MOhm.
Brightness range is 1.47 - 2.2V.
Darkness is 3.267V.
