# 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
#
# ⚠️ FIRST DEPLOY NEEDS A FULL CORE RESTART. reload_all only re-reads config
# for integrations that are already set up; rest_command was a brand-new domain
# on this instance, so until the restart the service didn't exist and every
# automation fire died with "Action rest_command.discord_server_alerts not
# found" — while check_config said valid. Verify with:
#   curl .../api/services | jq '[.[].domain] | index("rest_command")'
# 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)

            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.
