[MMM-Remote-Control] Cannot GET /api

Carsten · Mar 3, 2019, 11:10 AM

Hi there,

actually the module is working fine. i can access remote.html and all functions are working.
but as soon i try to access the api via command line i get “Cannot GET” error.

curl -X GET http://192.168.0.114:8080/api/module
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Error</title>
</head>
<body>
<pre>Cannot GET /api/module</pre>
</body>
</html>

any clue what is going on here?

@Carsten
Are you sure your link example is complete?
Is the following example $ curl -X GET http://magicmirrorip:8080/api/module/alert/showalert?message=Hello&timer=2000 working?
Details see https://github.com/Jopyth/MMM-Remote-Control/blob/master/API/README.md

Hi,
Yes i,m sure. It is from the Documentation you,ve posted.
But also your link Example don‘t work.

Cannot GET /api/module/alert/showalert

What i‘ve read till now it seems that the api folder isn‘t published.
I‘ve did an update of MM but didn‘t helped.

Further help is much appreciated.

I have exactly the same problem - all API calls result in error “Cannot GET /api/whatevermoduleitrytocall”. However, remote.html loads just fine.

As I have.

Edited: It was a mistake, sorry. I have same problem.

Same here too. I thought that perhaps we needed to have MMM-Api module installed but when I install that my MM won’t even start due to errors.

@AxLed said in [MMM-Remote-Control] Cannot GET /api:

api/module/alert/showalert?message=Hello&timer=2000

it looks like the api was changed, but not documented…

looking thru node_helper.js you can see all the commands

ip:port/remote?action=xxxxx&parms=???&parms2=???

the code lists these actions

            if (query.action === "SHUTDOWN") {
            if (query.action === "REBOOT") {
            if (query.action === "RESTART" || query.action === "STOP") {
            if (query.action === "USER_PRESENCE") {
            if (["MONITORON", "MONITOROFF", "MONITORTOGGLE", "MONITORSTATUS"].indexOf(query.action) !== -1) {
                this.monitorControl(query.action, opts, res);
            if (query.action === "HIDE" || query.action === "SHOW" || query.action === "TOGGLE") {
                self.sendSocketNotification(query.action, query);
            if (query.action === "BRIGHTNESS") {
                self.sendSocketNotification(query.action, query.value);
            if (query.action === "SAVE") {
            if (query.action === "MODULE_DATA") {
            if (query.action === "INSTALL") {
            if (query.action === "REFRESH") {
                self.sendSocketNotification(query.action);
            if (query.action === "HIDE_ALERT") {
                self.sendSocketNotification(query.action);
            if (query.action === "SHOW_ALERT") {
                self.sendSocketNotification(query.action, {
            if (query.action === "UPDATE") {
            if (query.action === 'NOTIFICATION') {
                    this.sendSocketNotification(query.action, { 'notification': query.notification, 'payload': payload });
            if (["MINIMIZE", "TOGGLEFULLSCREEN", "DEVTOOLS"].indexOf(query.action) !== -1) {
                    switch (query.action) {
            if (query.action === "DELAYED") {

to send an alert thru the api

http://mirror_ip:mirror_port/remote?action=SHOW_ALERT&message=foo&title=help&timer=10&type=alert

the remote.html does NOT use the api, but uses the socketNotifications pipe under the covers.
which is why it works, but the older /api/modulename… approach doesn’t

@sdetweil oh thank you so much !! I couldn’t find the way to use it :)

PolaricBear · Sep 27, 2019, 3:44 PM

I think I solved the problem. At least it worked for me.
Just delete file ./modules/package-lock.json. And restart the system.

@PolaricBear did u post this to the wrong topic?
