Reading the manual for the LHT65N/S (closest I could get as I could not find one for the exact model I have) I found at about sending commands via downlink to set the interval

No first chatgpt helped me by converting the at command to hex but then I found other referecens that a hex command starting with A8 would change the frequency

I have sent ll these commands in the messaging section all on port 85 and i fact I tried 5 as well and chatgpt analyses the live data feed back and says it is receiving the commands but if nothing is happening that perhaps the firmware does not allow this

This was a brand new device I took out the box so it should be update I would have thought

So what i need to know is can this device have the interval set by a hex message va messaging and if so what would that be to set it to say 1, 5, 10 and 20 minutes.

I have used port 85

After i can change the behavior I will go back to doing it via the api - but for the moment the messaging system will be fine for me

Thanks
