The home server pings `POST /heartbeat` every 15 minutes with a secret key\n2. `monitor.ts` runs every 15 minutes and checks if a heartbeat has been received in the last hour\n3. If not, a Pushcut notification is sent via `NOTIFY_SERVER_DOWN_URL`\n4. The status page at `/` renders the current state server-side — no client-side JS\n\n## Setup\n\n### Environment variables\n\n| Variable | Description |\n|---|---|\n| `SECRET_KEY` | Required on all heartbeat requests via `x-secret-key` header |\n| `NOTIFY_SERVER_DOWN_URL` | Pushcut webhook URL to call when the server is down |\n\n### Heartbeat cron job\n\nAdd this to your home server's crontab:\n\n```bash\n*/15 * * * * curl -X POST https://halffullheartbeat.val.run/heartbeat -H \"x-secret-key: YOUR_SECRET_KEY\"\n```\n\n## Files\n\n- `main.ts` — Hono HTTP server; serves the status page and accepts heartbeats\n- `monitor.ts` — Interval val that checks for downtime and triggers notifications\n",[148],"pulls","branches",1,"forks","envVars",{"_162":164,"_165":39},"connections",{"_162":39,"_163":39},"count","unfilledCount",2,"emptyCount",{"_18":147,"_20":148,"_114":149,"_116":-5,"_117":68,"_118":150,"_120":103,"_22":180,"_65":39,"_122":96,"_124":152,"_126":26,"_127":-5,"_171":181,"_85":182},{"_18":137,"_20":138,"_114":139,"_116":-5,"_117":68,"_118":140,"_120":103,"_22":177,"_65":142,"_122":143,"_124":144,"_126":26,"_127":145,"_171":178,"_85":179},{"_18":129,"_20":130,"_114":131,"_116":-5,"_117":68,"_118":66,"_120":103,"_22":174,"_65":133,"_122":134,"_124":135,"_126":26,"_127":-5,"_171":175,"_85":176},{"_18":112,"_20":113,"_114":115,"_116":-5,"_117":68,"_118":119,"_120":103,"_22":170,"_65":39,"_122":123,"_124":125,"_126":26,"_127":-5,"_171":172,"_85":173},["D",1771710090528],"children",[],[113],["D",1771710103911],[],[130],["D",1771710099361],[],[138],["D",1771707341995],[],[148],["D",1771295494247],["D",1789519256886],{"_16":17,"_83":79},{"_16":17,"_77":-5,"_78":79,"_32":33,"_80":81,"_82":26},{"_65":66,"_20":67,"_18":68,"_69":19,"_70":-5,"_71":-5,"_72":-5,"_73":-5,"_74":-5,"_75":21,"_76":17},"ctx",{"_58":-5,"_105":221,"_222":223,"_224":225,"_226":26,"_227":26,"_228":26,"_229":103,"_230":-5,"_231":-7,"_232":-7,"_233":39,"_234":26,"_235":26,"_236":-5,"_237":26,"_238":26,"_239":26,"_240":-5},"ENV",{"_192":193,"_194":195,"_196":67,"_197":198,"_199":200,"_201":202,"_203":204,"_205":206,"_207":208,"_209":210,"_211":212,"_213":214,"_215":216,"_217":218,"_219":220},"REACT_APP_SENTRY_DSN","https://586020d86f05489db63a554690acf1e9@o1398359.ingest.sentry.io/6724499","RENDER_GIT_COMMIT","e87eb04e707cf64e7e532c8e8ec395f209e17f15","RENDER_GIT_BRANCH","POSTHOG_API_TOKEN","phc_nmoyuAkStEZuUp69rYlg1DZgrIt19Gx0Y4Hwf8tGgJP","POSTHOG_API_HOST","https://wart.val.town","WEB_API_TEMPLATE","https://{val}.web.val.run","APP_URL","https://www.val.town","MODULE_URL","https://esm.town","VANITY_WEB_API_TEMPLATE","https://{label}.val.run/","DENOLS_URL","https://lsp.val.town","NODE_ENV","production","CLOUDFLARE_TURNSTILE_SITE_KEY","0x4AAAAAACtaIZJH7s9rBMZ6","GOOGLE_CLIENT_ID","875989696899-jtsqkhlbdv5jrlsk8631p7ipjg3c6o62.apps.googleusercontent.com","STRIPE_PUBLISHABLE_KEY","pk_live_51N2zvWEpZTTLipIkVEwXrUG9AT0yeOOEYxszarZT1jpsZV58Ly6wlg3SltZpHN26CUalOBmUSY7adQRQiSkCZz2500qSXNkf8Y","API_URL","https://api.val.town",[],"preferencesKeybindings","default","preferencesTheme","light","preferencesFixers","preferencesCopilot","preferencesSelectionAi","preferencesCloseBrackets","preferencesChatPanelState","preferencesDprint","preferencesDenofmt","notificationCount","flagDenols","isBusinessOrgMember","businessOrgHandle","isBusinessOrgAdmin","isHigherTownieTier","navCollapsed","currentOrgId"]
