BTW, why do you need Tbps speed network for home automation, except for video surveillance? A QoS guarantee in the order of 10s or 100s of milliseconds in latency will suffice, right? That should be easily achievable with a relatively slow speed *dedicated* network with only sensors and...
The old one was:
Serial Ethernet Converter (RS232, RS485) - PRO
https://www.usconverters.com/rs485-ethernet-converter
I don't recommend it as it often hangs and I had to power-cycle it every week or so.
The new one is:
StarTech NETRS2321P...
That's a good question.
I choose the baud rate as specified in PC Access: 9600, which apparently is the only serial communication parameter one can select in PC Access other than "Omni-Link" (under "Function" in Setup|Expansion|Serial in PC Access).
Maybe "Omni-Link" spec defines the...
Thanks for the response.
Yes, it always worked since I set it up 2-3 years ago except once the 5V power supply to serial-to-ethernet failed.
BTW, I could resolve the mystery today. I could finally fish out a serial to USB cable from my junk collection and connect a laptop directly to the LT...
How do I reset Omni LT controller board which is not responding to serial port/PC Access? Is there a way to do it without disconnecting the battery?
I access the serial port of our old Omni LT controller via an external serial-to-ethernet board (so that I can access it from anywhere). The...
Our 2001-era Omni LT presently works fine with two HAI Omnistat RC-80s controlling our 2 independent HVAC units. I am thinking of replacing RC-80s with Nest thermostats as our local power company is almost giving Nest for free. Is it possible to replace RC-80 with a Nest thermostat and still be...
Yes, I agree that local storage is cheap. An ideal minimalist solution would be local storage with cloud backup.
Cloud provides storage at a secure remote location so that someone can't walk away with your drive. Some added perks of cloud services include data archival, event detection...
Wifi and cloud storage (for example, for video surveillance) works great when there is connectivity. The problem is they depend on too many systems beyond your home.
In general, the RAS (reliability, availability and servicebility) of the system goes down if it relies on internet or wifi to...
Our 2001-era Omni LT's console has been constantly showing the error message "BATTERY LOW TRBL NOW". It gives an audio alarm (on console) at oddest hours of night one can imagine, almost every night, as well.
The Owner's Manual says I should replace the battery; recommended battery type is a...
Does anyone has experience with HAI/Leviton Cellular Communication Center (C3)
http://dealerqa.leviton.com/sites/dealer.leviton.com/files/C3-Instruction-Sheet-English.pdf ?
It uses GSM network though. Actually you don't need any high speed LTE network for this; reliability is the most important...
Pete, Thanks for the suggestion.
It looks like the only Hometroller with serial port is their most expensive (~$1K) model! :(
Maybe I should try to find a small Linux/Win board with serial port that can run Homeseer.
Or even a better idea would be to switch to an OmniPro II or some such...
Barry, Thank you for the suggestions.
I have an Omni LT panel. I don't see LT listed on Leviton's product data sheet for Omni Notifier https://www.leviton.com/en/docs/Emailtext_notif_Tsht_BW_v1p1.pdf
Omni LT system supports only a serial (RS-232) link. I thought HomeSeer needs ethernet...
Hi,
I have been observing that the clock on my Omni LT was drifting a few seconds every day and as a result I have to re-synch clock every week using PC Access Dealer (via Communications -> Set Controller Time).
I noticed that there is a field called "Clock Adjust" under Miscellaneous...
