Hi,
I have Shelly Plus 1PM.
I did not find any answer from mJs scripting section of how to store variable locally so that I can recover it after reboot?
I have installation that boots often and it is expected to be functional immediately after powerup. Including situations where wlan is not always available. I must store configurations into cloud because configurations are managed globally from cloud.

Hi,
Luckily I managed to make it work.
Thanks for the replies. Those are needed to keep things going.

Hi,
Good info! I guess you could setup DNS from router, but I guess it should be automatic if IP setting is set to DHCP. I found these device settings from Shelly:
...
"sta1": {
"ssid": "8A1170",
"is_open": false,
"enable": true,
"ipv4mode": "dhcp",
"ip": null,
"netmask": null,
"gw": null,
"nameserver": null
}
...
...
I had problem with my mobile hotspot and router. Would that point to problems in Shelly FW itself? Local desktop setup in development phase is not uncommon.

I tried the other mqtt-announce.js code with these debugs:
DEBUG LOG
Connected.

Hi,
Thanks for the reply. My problem is still existing unfortunately. I connected to home WLAN from hotspot but no changes. I tried username password matching (and booting) with broker but no luck.
I really would need a guidance of how and what tools I could use to dig out the problem. Does device have some deep debug capabilities?
PS. otherwise very innovative products from Shelly!

Hi,
Can you make it work via mobile hotspot? That is the only odd setup here that I can think off.

Hi,

Hi,
I did once more did not help: Code states the same "not connected". I used BLE functionality here and it works. Anyway problem happens even with minimalistic mqtt code.
// Scan options
let scanOptions = {
duration_ms: BLE.Scanner.INFINITE_SCAN, // Scan indefinitely
active: false, // Use passive scanning
interval_ms: 150,
window_ms: 50,
};
// Scan callback
function scanCB(ev, res) {
if (ev !== BLE.Scanner.SCAN_RESULT) return;
// Get the address and signal strength of the beacon
let addr = res.addr;
let rssi = res.rssi;
// Publish the beacon data to the MQTT topic
//MQTT.publish("beacons", JSON.stringify({ addres: addr, signal: rssi }));
//print(addr);
}
// Start scanning
BLE.Scanner.Start(scanOptions, scanCB);
// Publish a message every 10 seconds to confirm that the code is running
function mqttWatchdog(){
let status = MQTT.isConnected();
if(status){
print("Running");
MQTT.publish("beacons", "Running", 0, true);
print("Running");
} else {
print("Not connected");
}
}
Timer.set(2000, true, mqttWatchdog);
Hi,
I have been able to make a MQTT connection with hivemq broker example provided with mqtt-announce.js. For some reason the UI changed a day ago and ever since I have had problems with connecting the broker. I have booted many times but no connection is made. I don't know how to debug any further?
