I am getting conflicting information from a dealer. On one call they give me a brochure on MobilLink and tell me it's a satellite based system, but the brochure says cell phone link. I go to visit them and they tell me they are using Omnimetrix monitoring and it uses satellite communication. So, I looked it up on the web and it says 3G/4G or LTE, but can link with Iridium. Sounds expensive for the Iridium part.

Anyone know what the real story is on Omnimetrix. I see from another post that MobilLink may go away.

My situation is that I have NO cell service. I do have a land line that does NOT support internet, and my satellite link (which uses a dish) for internet is almost non-existant so unless there is some kind of dish to focus the satellite signal, I'm not convinced the monitor will work here.

Where the heck are you? :confused:

There's a thread in the installation section about a project on Github that allows minitoring of many Generac and other brand gensets. One option of this system is to send and receive emails to report events and for remote starts. If your satellite internet link can support the sending and receiving of emails, this might be for you.

I'm in a rural area of east Texas where there are lots of tall trees all around which affects the satellite signal and also in a bowl so that there is a ridge between me and the rest of the world so all the radio signals are way up in the air. I will need an antenna tower to catch the signals and I've not been able to determine how tall the tower needs to be but has to be taller than I want to mess with. I know this doesn't sound very good for keeping in touch with people, but our neighbors make it a point to visit so I'm not sure I want to change this.

Mobile Link depends on Verizon's CDMA cell phone service, which is being phased out. There is a new version of Mobile Link using internet access coming out soon, and some other folks here may have more info.

Omnimetrix is offering some deals now - clearly targeted to current Mobile Link customers.

MParks referred to the excellent GenMon, which requires some DIY and electronics ability.

The only way any of the systems can connect to the world with the end of the Mobile Link CDMA version approaching, is via internet access. Omnimetrix might have a low rate Iridium that is not expensive (Iridium has many specialty plans.)

Who is the provider of your internet access? It should, and usually does, work well, except for some lag online gamers don't like, and extra charges to heavy use. Do you have Viasat, HughesNet, or something else?

I have HughesNet. Using speedtest.net I get varying speeds - with a download speed under 1Mbps and up and an upload speed of unmeasurable and up. I'm supposed to get 15 Mbps down, but have never seen it that high. I feel fortunate to get in the 2 to 3 range. I don't use it for gaming, ping times are in the 800 range.

There seems to be something wrong - either the dish positioning or a config problem. You should get at least 10 Mbps down and 1-2 Mbps up - unless they have you permanently limited by the Fair Access Policy, either because of a billing error, or possibly something you have connected is trying to do endless background downloads. (A Windows PC stuck in a WindowsUpdate loop or similar.)

The old Mobile Link is going away. It's not even currently offered for sale thru the Generac Sales Portal. All the new Air Cooled units (possibly the liquid cooled now too) are coming with a new WIFI system built into the controller. These controllers will all be Version 2.x.

The newer wifi systems will offer 3 tiers of service. They all come with a FREE basic service which offers basic notices (ready to run, caution,fault) . The expanded version is something like $49 per year and this will alert you to generator operations, maintenance issues, faults, etc. Then there's an upgraded level that offers you even more info, but i don't recall the cost for this level.

So far i have sold 3 of the newer units, but have not installed them yet. I'll know soon enuf how easy they are to link into the customers WiFi system. I hope that it will be straight forward.

I also believe that Mobile Link thru Verizon cellular link is due to go away sometimes in 2020. I believe some other carrier may pick it up. I hope so, otherwise i'm going to have some irate customers.

I was also told that there may be some backward comparable version of the WiFi controller rolling out sometimes, in order to update older units with version 1.x controllers....but time will tell.

Sprint supposedly will keep CDMA until the end of 2021. They could offer deals - if only to make Verizon look bad.

The Mobile Links will not work on Sprint's CDMA network. The big providers are also phasing out support of 3G and lower devices by 2020. There will be 4G cellular replacements for older Generac generators available to the dealers by the end of Q4/Q1.

The termination date for the Verizon CDMA network in the US is 12/31/19

Ok i now have the actual info about mobile links future. The existing Mobile Link G2 network offered by Verizon goes away in Dec 2019. However, next year Generac will be offering an upgrade kit for the existing mobile link units to operate on the Verizon 4G network. Therefore all older mobile link units will still be able to work.

There will also be an option to add cellular access to the new WiFi Mobile Link units that are coming as standard equipment on all Generac units. This will allow uses where there is no WiFi in use, but there is Verizon wireless service available.

16K Generac Genmon Hardware Installation

I was fascinated by Jason's Genmon project so I built and installed the hardware. I have attached a couple of photos showing it in my newly installed Generac 7037. Jason's project was documented perfectly and I was able to complete it just by following the directions on the wiki. I do have some Raspberry Pi experience but I would say anyone could do this project if they can follow instructions. I am a retired technician so making the cables required was not a problem but plenty of alternate options are mentioned in the wiki and this thread for those with no cable making experience. If you are hardware challenged, I can help you by building cables.
I can answer questions about my installation but I don't think I can improve on the existing documentation on the Genmon hardware. I did not change anything and it came up the first time. I did choose to to use Ethernet and POE for mine as I did not want an external antenna. This also can be found in the wiki. My generator is located just a few feet from the house and I was worried that I would damage any antenna during snow removal (New England :) ).
Thanks to the authors of the fiber convertor posts. Never thought of that and I think I will change to fiber to prevent lightning damage.

Thought it may cause some confusion so wanted to add that Ethernet cable is not shown in hardware photo. It plugs into the POE adapter just above hole that the serial cable wire is going through.

For mine, I decided to locate the PI indoors, mounted in one of the tiny PI plastic cases. There was room inside the case for a board-only (no connectors) RS232 to TTL convertor. It's connected to the generator by about 20 feet of outdoor 4 conductor shielded cable. The PI is grounded to the generator by one conductor, and the shield is grounded at only one end. I don't think there is a big lightning risk due to the short run, but to add a bit more protection, I put 1 K resistors in series with the RS232 lines at the convertor. The RS232 impedance is high enough that these don't affect the signal. There are no CRC errors. I recently built another one this way on request - and it also shows no CRC errors.

I did try using the 5 volt line to power the PI, but I found the load pulled the voltage below 4.5 (at the generator end), so I used a separate wall-wart supply.

Lightning

Inside or outside, I think lightning is a consideration that I forgot about. For that reason I will try some inexpensive fiber to Ethernet [URL="https://www.amazon.com/gp/product/B07896T2SF/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1"]convertors[/URL]

I am a retired technician and I have seen what lightning will do as I had to repair the damage it caused to broadcast intercom equipment, when possible. In my case there is about 20' of Ethernet outside and about 8' is exposed in plastic waterproof flex, the rest is in underground plastic pipe. The convertors will stop a closeby ground strike or direct strike to the generator from inducing a current flow in the cable.

At $29 for the pair of convertors and the cost of a fiber, I'll give it a try. Serial media convertors are available as well but I think they are more expensive but distance and grounding issues will be solved for most serial applications. Your approach has the advantage of protecting the Pi as anything in the generator, including the generator can be damaged by lightning.

I will post how these work out.

Those should work fine.

The longer the outside run the greater chance of lightning being a risk. The two generators I had connected are 5 feet from the houses, with the exterior cable runs only about 6-7 feet.

I did see pair of RS232 convertors on AliExpress for about $45.00 plus shipping.
