tuya-cloud-to-influxdb

Using Tuya cloud API to push data from device to influxdb. As a side effect it's possible to get various device information from the tuya cloud using CLI.

This is a work-in-progress, so expect breaking changes :).

Note: this was only tested with branded sockets with power metering. The sole purpose was to get the metering data and push it to influxdb and visualise using grafana.

Available commands

Usage: cli [options] [command]

Options:
  -V, --version                        output the version number
  -v, --verbose                        Increase verbosity, may be appied multiple times
  -h, --help                           output usage information

Commands:
  auth <user> <pass>                   Authorize the Tuya client (this will save only the session ID in the config, no password will be saved)
  list                                 list all devices
  show [options] [devName]             show current values available on the devices (optionally filter by group/device name)
  switch [options] <on|off> [devName]  switch state of the device (optionally filter by group/device name)
  stats-monthly [options] [devName]    retrieve monthly cumulative stats [works for power monitoring]
  stats-daily [options] [devName]      retrieve daily cumulative stats [works for power monitoring]
  time                                 get unix time from the tuya servers (use it to test session validity)
  config-tuya [options]                manipulate Tuya API configuration
  config-influx [options]              manipulate InfluxDB connection configuration

Basic usage

First You need to set-up the authentication keys to be used with the CLI. The keys are per-application (eg. Tuya, SmartLife or other branded ones). On details regarding how to get them - check tuya-sign-hacking repo. The below example configures the keys being used in Tuya app

./cli.js config-tuya --api-key 3fjrekuxank9eaej3gcx
./cli.js config-tuya --api-secret aq7xvqcyqcnegvew793pqjmhv77rneqc
./cli.js config-tuya --api-secret2 vay9g59g9g99qf3rtqptmc3emhkanwkx
./cli.js config-tuya --api-cert-sign "93:21:9F:C2:73:E2:20:0F:4A:DE:E5:F7:19:1D:C6:56:BA:2A:2D:7B:2F:F5:D2:4C:D5:5C:4B:61:55:00:1E:40"

After the configuration you need to open session (authorize) with Tuya cloud. Note: username and password will not be stored in the config file - only the resulting session ID

./cli.js auth username password

Verify if everything works by getting time from the Tuya Cloud:

./cli.js time
✔ getting time
{ validTime: 1800, time: 1582799524 }

Get device list from the cloud

./cli.js list
✔ getting device list
group: RR       device: Pralka (devId: 462683xxxxxxxxxxxxxx groupId: 2xxxxxx)
group: RR       device: Biurko (devId: 462683xxxxxxxxxxxxxx groupId: 2xxxxxx)

Get device data from the cloud

./cli.js show
✔ getting device list
✔ getting device schemas
Device: Pralka
[rw] {1} switch_1:      true
[rw] {9} countdown_1:   0 s
[rw] {17} add_ele:      0.001
[ro] {18} cur_current:  0 mA
[ro] {19} cur_power:    0 W
[ro] {20} cur_voltage:  230.2 V
[ro] {21} test_bit:     1
[ro] {22} voltage_coe:  652
[ro] {23} electric_coe: 30909
[ro] {24} power_coe:    17875
[ro] {25} electricity_coe:      1165
[ro] {26} fault:        0
Device: Biurko
[rw] {1} switch_1:      true
[rw] {9} countdown_1:   0 s
[rw] {17} add_ele:      0.019
[ro] {18} cur_current:  304 mA
[ro] {19} cur_power:    44.7 W
[ro] {20} cur_voltage:  229.6 V
[ro] {21} test_bit:     1
[ro] {22} voltage_coe:  617
[ro] {23} electric_coe: 30029
[ro] {24} power_coe:    17084
[ro] {25} electricity_coe:      1220
[ro] {26} fault:        0

You can use -v option to list all retrived values (eg. localKey if You want to control the devices locally). -vv will give You even more verbose output.

Advanced usage

Configure influxDB:

./cli.js config-influx --measurement tuya
./cli.js config-influx --uri http://example.com/database

Upload the instantenous data at a given interval:

screen
while :; do date; ./cli.js show -u; sleep $((5*60)); done

Setup cron to upload daily stats (for the previous day at 2:00 am every day)

0 2 * * * /path/to/tuya-cloud-to-influxdb/cli.js stats-daily --yesterday -u

Additionaly: push manually previus stats using cli.

Create nice graphs in Grafana :) TODO: image/json?
