Clarification on V.35 firmware issues


Recommended Posts

I hate to ask this question that has been covered before, but I have been unable to SEARCH and find the previous postings.

 

I am looking for clarification of the device types, with V.35 firmware, that cause communication problems. Is it some or all of the following devices?

 

- Switchlinc dimmers 2476D

- Switchlinc relays 2476S

- Icon dimmers 2876D

- Icon relays 2876S

 

Are there other V.35 devices that cause problems as well?

 

Thanks in advance!

I have recently looking at past posts on this topic. I have had good luck with a search on "V35" (no period).

 

I understand that this affects switchlinc dimmers and relays, but not necessarily keypads or modules. I do not recall any discussion specifically about whether this affected icon models or only the full-priced models. I was not looking for this clarification, however, so I may have missed it.

Michel,

 

If the problem units are only a fraction of the total V.35 switches made (if I understand your comment above), is there any way to tell which ones may be affected? Is their address a clue (depending on how they are assigned during manufacturing)?

 

Thanks,

If your v.35 devices are dimmers then it is almost 100%.

Some folks use a 3-wire appliance cord available from most any home improvement store. They have a plug on one end and bare wire connections on the other. Not very expensive. This arrangment allows any wired Insteon device to be easily wired up and plugged in to test. The device can even be moved around to different outlets if that is useful. There is a person on the Smarthome forum that tests every device being installed that way. He does a factory reset and tests the device before attempting to install the device. It eliminates all questions about wiring and a working device before installed in the wall.

I have considered making a wire like that with alligator clips on the end to make it really easy.

 

I was wondering if the v35 switches exhibit a consistent identifiable characteristic that tells you it is going to cause problems. If it is one of those "every once in a while" things, I don't know how I could test for it.

I strongly recommend against alligator clips when working around 120V AC. They are too easily dislodged or shorted and they do not provide the insulation needed to protect from electrical shock. Too much risk of fire and SERIOUS personal injury. Making a power cord is fine but use conventional wire nuts between the power cord and the Insteon device connections. They provide a secure mechanical connection as well as positive insulation. Always cap the red load wire on the Insteon device unless connecting to some test load. The load is not needed to see a v35 device failure. Some of the devices in my test bed are done with appliance cords if they are only being tested short term.

 

I've not had any v35 devices in my inventory but from posts on various forums powerline communication seems to be the symptom and it is immediate. The failures can be with the v35 device itself or they cause interference with other Insteon devices. It looks like an internal PLM issue but there has not been any statement of cause from Smarthome or Smartlabs that I am aware of.

 

Add the device to the ISY and try using it in the planned way. Links work regardless of the device install location. The switch can even be moved around to different outlets to see if relative location to other Insteon devices makes a difference.

 

According to Steve Lee of Smarthome v35 devices do not create a problem in every environment. Also I think Smarthome will replace them if you are the original purchaser from Smarthome.

I use Wago 222-412 lever nuts for this purpose. They are the best reusable option for making a test cable. Very quick, very secure, and they do not mess up the nicely tinned end of insteon switches like wire nuts sometimes do.

 

The 5 port ones are also the best item I have found for those nightmare neutral messes in a box with three or more switches. It allows you to work with one wire at a time instead of trying to get 7 or more neutrals into one wire nut.

Happy Thanksgiving!

 

Smarthome is refusing to change out the switches becuase they stated:

 

1) There is nothing wrong with v35, period. It is ISY's fault if there is any fault at all.

2) Mine are 2 years and 2 months old.

 

Regarding the alligator clips, I have insulated ones. I wouldn't put a load on the switch, so the current draw would be negligable. It would be no different than the thousands of times I have touched my multimeter to various hot wires.

 

If there were a straight-forward test, I would love to know what it was. I really don't think running around the house plugging it in in different places and just seeing if anything goes wrong is very doable. I wouldn't even know what to look for.

 

At what level of integration would it mess things up?

1) Just being connected to the house AC?

2) Being linked to ISY?

3) Being linked to other devices?

4) Does it matter if a load is attached?

 

And would it be consistent or highly random in its problematic behavior? Again, it would be very challenging to test each one for a few weeks and wonder if random errors were becuase of it or some other random cause.[/i]

Here is a link and excerpt from an slee post on the Smarthome forum that documents v35 is problem at some installations and v37 replacements resolve the problem. A search request on Smarthome forum for "switchlinc v35" for All Words will provide a few more hits.

There are some installations that have an effect on the v35 switches. This could be caused my many things but the v37 switches that are shipping now seem to work just fine in the installs where v35 are acting up. Most of my house still has version v35 switches and I am not experiencing any issues.

 

Please feel free to contact me so I can help you out with your installation.
