# Water-heater DSI fault → Discord ping in the server-alerts channel.
#
# The CAN node decodes the heater's DSI lockout (node 95 page-3 b0 bit5 —
# see canbus/README.md); when the burner fails to light (usually an empty
# propane tank) the module latches the fault and this fires the webhook.
#
# Deploy to Pi: /config/packages/dsi_fault_alert.yaml
# Repo copy:    canbus/ha/dsi_fault_alert.yaml
# Secret:       discord_server_alerts_webhook in the Pi's /config/secrets.yaml
#               (NOT the Gatus webhook — that one posts somewhere Wes doesn't
#               read; this one is confirmed delivering to the alerts channel)

      10s 'for' debounces a single glitched broadcast frame; a real lockout
      is latched by the module so it easily survives the wait.

            you're out of propane again. (Or the igniter finally died, but let's be honest,
            it's the propane.) The heater is in lockout — swap the tank, then
            cycle the heater off/on to relight.

            tank gauge and say "eh, it's fine."
