Generate sketch for ESP 8266 (ESP-01) to count gas usage, send to influxDB

I require a sketch for an ESP 8266 (ESP 01) as follows:
- ESP 01 has 2 GPIO so the setup should work, if not a node CMU can be used

- read out/count impulse of reed contact (gas meter counter)
o https://mysmartshop.de/products/elster-impulsnehmer-in-z62-fur-elster-balgengaszahleresp 8266
- read out voltage meter

- display on simple website as follows (access via IP if ESP is online)
o text: gas counter
o gas counter today: xxx value (each count is 0,001 m3 )
o voltage: xxx Volt
o Date
- send data to influx DB
o gas counts or gas usage in m3
o voltage
- connect via wlan only if needed, e.g. only once in 10 minutes to save energy
o send all gas counts within that time
o send current voltage
