Setting NTP server and getting date/time/server info

[davoau]

Hi, I am trying to set the ntp server address and timezone and I am guessing I require this this for correct energy metering as it does on tasmota - todays usage resets to zero at midnight.

I have tried the below commands to set ntp info. - I have an ntp server running on 10.0.2.1 / ntp.intranet.lan, and tried to set it both with ip address and domain name.

mosquitto_pub -t "obkFFD00991/ntp_setServer/set" -m "10.0.2.1"
mosquitto_pub -t "obkFFD00991/ntp_setServer/set" -m "ntp.intranet.lan"
mosquitto_pub -t "obkFFD00991/ntp_timeZoneOfs/set" -m "+10:00"

But if I try to retrieve the info all I get is 10, which I guess is the +10:00 of timesone

the below mqtt output is all that I see.

obkFFD00991/ntp_info/get
obkFFD00991/0/get 10

Firmware:

• Build on Apr 19 2023 12:34:41 version 1.17.11
• Aubess 16A Tuya Smart WiFi Switch with Power Metering
• Chip/model: BK7231N
• P8 - LED_n, P23 Btn, P24 TglChanOnTgl, 26 REL
• Startup Command: startDriver BL0942

Everything else seems to work as expected...

Hello, I think that obkFFD00991/ntp_setServer/set syntax is not correct, this is for channels. For commands, we do: cmnd/obksmth/ntp_setServer with payload server IP (try IP first).

Btw, why don't you try commands first on the WWW panel, and then check with MQTT?

Hi, I did try cmnd/ but that made no difference - the below would not work.

mosquitto_pub -t "cmnd/obkFFD00991/1/set" -m "1"
mosquitto_pub -t "cmnd/obkFFD00991/1/set" -m "0"

If I use: mosquitto_pub -t "obkFFD00991/1/set" -m "1" it will turn the switch on and mosquitto_pub -t "obkFFD00991/1/set" -m "0" will turn it off.

and the logs show that:

Info:MQTT:MQTT client in mqtt_incoming_publish_cb topic obkFFD00991/1/set
Info:MQTT:MQTT client in mqtt_incoming_data_cb data is 0 for ch 1

If I input the command ntp_timeZoneOfs +10:00 using WEB APPLICATION / LOGS / COMMANDS box at bottom of page I see in logs: Error:CMD:cmd ntp_timeZoneOfs NOT found (args +10:00) Info:CMD:[WebApp Cmd 'ntp_timeZoneOfs +10:00' Result] Unknown command

I also tried ntp_timeZoneOfs "+10:00"

If is send a mqtt command to set the ntp server logs show:

Info:MQTT:MQTT client in mqtt_incoming_publish_cb topic obkFFD00991/ntp_setServer/set
Info:MQTT:MQTT client in mqtt_incoming_data_cb data is 10.0.2.1 for ch 0
Info:GEN:CHANNEL_Set channel 0 has changed to 10 (flags 0)

It only takes the first octal of the ip address - 10.

and to set timezone:

Info:MQTT:MQTT client in mqtt_incoming_publish_cb topic obkFFD00991/ntp_timeZoneOfs/set
Info:MQTT:MQTT client in mqtt_incoming_data_cb data is +10:00 for ch 0
Info:GEN:No change in channel 0 (still set to 10) - ignoring

It ignores command because its already set to 10 from ip address:

If is set timezone to +12 logs show:

Info:MQTT:MQTT client in mqtt_incoming_publish_cb topic obkFFD00991/ntp_timeZoneOfs/set
Info:MQTT:MQTT client in mqtt_incoming_data_cb data is +12:00 for ch 0
Info:GEN:CHANNEL_Set channel 0 has changed to 12 (flags 0)

If i set ntp server to 10.0.2.1 and the timezone to +10:00 it ignores because the ip address has already set the timezone data to 10 and logs show:

Info:MQTT:MQTT client in mqtt_incoming_publish_cb topic obkFFD00991/ntp_setServer/set
Info:MQTT:MQTT client in mqtt_incoming_data_cb data is 10.0.2.1 for ch 0
Info:GEN:CHANNEL_Set channel 0 has changed to 10 (flags 0)

Info:MQTT:MQTT client in mqtt_incoming_publish_cb topic obkFFD00991/ntp_timeZoneOfs/set
Info:MQTT:MQTT client in mqtt_incoming_data_cb data is +10:00 for ch 0
Info:GEN:No change in channel 0 (still set to 10) - ignoring

Am i doing something wrong or is it a bug ?

I have also noticed that if the smart switch is turned off (disconnected from power), then turned on again it does not send any mqtt messages and I am unable to connect to it using a browser until I push the physical button on the switch.

All your queries are still incorrect.

For channels (switch) this is correct:

obkFFD00991/1/set

I said, for channels. And only for channels. So when you do: it tries to parse value as integer and sets channel 0 to 10... it's not a command.

For commands, you do this:

cmnd/obkFFD00991/ntp_timeZoneOfs with payload 10 or anything

I have also noticed that if the smart switch is turned off (disconnected from power), then turned on again it does not send any mqtt messages and I am unable to connect to it using a browser until I push the physical button on the switch.

I don't know about the connect issue, it seems strange, but for MQTT, we have flag "broadcast self state on mqtt connect"

And regarding that:

You should start NTP driver first. It is not run by default. You can set startup in either short startup command or in a autoexec.bat

Thanks for the info above. I assumed NTP would be loaded by default.

After loading NTP driver I set the ntp server and time offset

root@pi1:~# mosquitto_pub -t "cmnd/obkFFD00991/ntp_setServer" -m "ntp.intranet.lan"
root@pi1:~# mosquitto_pub -t "cmnd/obkFFD00991/ntp_timeZoneOfs" -m "+10:00"

what i see in webapp log

Info:MQTT:MQTT client in mqtt_incoming_publish_cb topic cmnd/obkFFD00991/ntp_info
Info:NTP:Server=ntp.intranet.lan, Time offset=36000

And on front page of switch it says: NTP: Syncing with ntp.intranet.lan

So it looks like it is all working. However I noticed there is no energy consumption today, only energy total, so I will have to do the rollover with homeassistant.

I will investigate the problem with no mqtt messages until button push. I had the same problem this morning when I turned on the switch. However after playing around with the NTP stuff and then restarting (only switched off for 30 seconds), it connected, and started sending mqtt messages to broker, and I could issue the command over mqtt to turn on switch and it worked. Will leave off overnight again and see what happens.

Anyways thanks for all the help.
