Ok, thanks.  I had no idea it even existed.  I've used Comcast/Xfinity for 20? years, at different locations and always was granted a semi-permanent public IP easily accessible from the Internet.   I use Digital Ocean for different purposes, so it looks easy to set up a bypass if need be:  ...

Not sure I understand.  What does not see your home router from the Internet ?  You can directly connect to your home network from the Internet, as I am sure you know, Why introduce a middleman ?   Sorry for the late reaction to your response.

Am I missing something ?   Why do you need Oracle VPS as a middleman?  Why not connect directly to your router openvpn server ?   Thx.

I have a setup similar to wkearny99's. When I bought the house, there had been two ordinary push fans, in the WC and the bathroom itself, sending exhaust air to a Y-ed outlet. The inspector noticed and told me about the code violation (you cannot push  the air to the same exhaust pipe).  So, I...

Just tried the HA integration.  It is much better in the sense of traffic -- if there's no motion, it sleeps form10 seconds, so much less voluble.

I looked briefly at the Onvif to MQTT  docker. It works fine, but it is rather talkative, hundreds of kilobytes during a short period of time(as seen by wireshark).  It looks like it keeps polling the camera for motion events rather than the camera pushing events when they occur.   My idea was...

I am not familiar with Elk two-way.  H/GE are the same in the sense of blindly firing a packet and hoping it will arrive. Usually, it does mainly due to being low frequency and thus penetrating obstacles better than 2.4GHz signals.   Zigbee and Z-wave have worse signal propagation...

It's a good question. Not sure how to test that. Perhaps, you can put the sensor in a metal enclosure, trigger it there, make sure that elk did not receive the status change packet, let the sensor out of the Faraday cage and wait 70 minutes to see if the heartbeat updates the status.  Something...

You are right.  Here's a Honeywell door sensor sending status every 70 minutes:   2020-9-5 9:24:18 PM    RFX    0212973:0:1:1:1:0:0 heartbeat + violated (bit 1 -> heartbeat+ bit 2 violated) 2020-9-5 8:12:42 PM    RFX    0212973:0:0:1:1:0:0 violated 2020-9-5 8:09:32 PM    RFX  ...

Right, H/GE wireless sensors are very rudimentary, there is no acknowledgement or re-transmission if the packet was lost.

There are two kinds of Honeywell/GE wireless sensors, and probably other brands. A motion sensor sends a signal when motion is detected and then sleeps for 3min.  A door sensor is triggered/cleared similarly to a wired sensor (a signal is sent when it's violated and another one is sent when it's...

When I had an Elk with a GE receiver, I used GE door transmitters with a printed board sensor for a sump pump and a dishwasher. They were quite reliable, perhaps too sensitive even, a spider could trigger the outdoor one.  You can do the same with a Honewell transmitter.

There are two problems with this solution: 1. Apparently, no access to the original AP, so no way to modify the antenna. 2. The bridge idea assumes that clients have wired Ethernet connection.

Well, my understanding is that there is no access to the AP/original router, just to the wireless signal.  So, options are rather limited.

Perhaps, I was too categorical.   The repeater may work depending on its ability to communicate with the original AP.  I.e. it should be able to receive reliably from the AP and the repeater  transmit power should be good enough for the AP to hear from it back.  Maybe you can find a location...

If there is no wired port, I am afraid he is out of luck.  Repeaters usually makes things worse by creating additional interference on the same wireless channel.   https://community.spiceworks.com/topic/988492-why-don-t-wi-fi-repeaters-work-very-well-ok-why-do-they-suck

The surgical mask has always been used as a source filter preventing the patient from infection, not the other way around. Even in this case, there is some doubt as to their efficacy: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4480558/   A recent study finds little protection when wearing a...

And California and Arizona too experienced dramatic spikes in new cases.   Perhaps, the reasoning is as follows: better let some young people get infected in bars than rioting in the streets; for the currently infected demographic median age of 34 (FL), the IFR is half of that of the 2009 swine...

After the restrictions were relaxed, an increase in coronavirus cases is to be expected. There is some hope that the dramatic increase in the new cases may not translate into e corresponding increase in the number of deaths because now the number of cases is skewed towards younger population (as...

  Looks similar to what I used to have in my previous house.  The messiest part was/is to wire all the current transformers and connect them through the conduit to the measuring module. I used Brultech, iotaWatt did not exist at the time.   When I moved, I disconnected everything and took with...
