+# TV Remote
+A [BangleJS 2](https://shop.espruino.com/banglejs2) app that allows the user to send TV input signals from their watch to their TV. 
+Currenly there is only support for Panasonic viera TV's however support for other brands may be considered in interest is there.
 
+# Requirements
+1. The [Bangle GadgetBridge App](https://www.espruino.com/Gadgetbridge) with permissions allowed for `http requests`.
+2. A domain name and DNS created.
+3. A webserver that the DNS points to, that is set up to receive and process the watch http requests. [Here](https://github.com/Guptilious/banglejs-tvremote-webserver) is one I have created that should complete the full set up for users - provided they have their own domain name and DNS created.
+
+# Set Up
+You will need to upload the below JSON file to your BangleJS, which will be used for config settings. At minimum you must provide:
+* `webServerDNS` address, which points to your webserver.
+* `username` which should mirror what is included in your webservers auth config. If using my webserver it would be `config.json`.
+* `password` which should mirror what is included in your webservers auth config. If using my webserver it would be `config.json`.
+
+`port` and `tvIp` are optional as they can be manually assigned and updated via the tvremote watch app settings.
+
+    ## Tv remote config example
+    require("Storage").write("tvremote.settings.json", {
+      "webServerDns": "",
+      "tvIp": "",
+      "port": "",
+      "username": "",
+      "password": ""
+    });
