Push a Single "Latest" Telemetry Record (no Timestamp)

Source: R/push_to_thingsboard.R
tb_push_latest_telemetry.Rd

Sends a flat {"key": value, ...} JSON object to the ThingsBoard telemetry endpoint, letting the server stamp it with the current time. This is the simplest possible telemetry POST and is useful both as a smoke test for the device-token auth path and as a fallback when the bulk-with-ts format is rejected (some ThingsBoard Cloud Maker tier configurations return an opaque HTTP 500 to the array-of-records form even though the same device accepts attributes and latest-style single records).

Usage

tb_push_latest_telemetry(
  values,
  device_token,
  host = Sys.getenv("TB_HOST", unset = "https://thingsboard.cloud")
)

Arguments

values

named list (or named numeric vector) of telemetry key/value pairs.

device_token

ThingsBoard device access token.

host

base URL of the ThingsBoard instance. Defaults to env var TB_HOST if set, otherwise "https://thingsboard.cloud".

Value

invisibly the number of keys that were sent.

Examples

if (FALSE) { # \dontrun{
tb_push_latest_telemetry(
  values = list(`GW-Stand` = 35.6, `Wassertemperatur` = 11.2),
  device_token = Sys.getenv("TB_DEVICE_TOKEN")
)
} # }
