EMI / Missed commands. How to resend an action?

I’m using the API to the LC7001 successfully and love it. But I have 1 problem:

About 1% of all submissions between the LC7001 and the actual switch fail. So eg when I turn a light OFF either via the API or the Android App, the LC7001 shows the switch as OFF, while in reality the light remains still ON. This seems to be dependent on the distance between the switch and the LC7001, and also dependent on time of day. So I suspect Radio interference (EMI).

So the question is whether it’s possible via the Adorne API to remediate such a situation. In other words can I send a second command to force the LC7001 to turn off a switch again even though the LC7001 thinks is already OFF?

So currently if I simply send the same message again (ie. {‘Service’: ‘SetZoneProperties’, ‘ZID’: 0, ‘ID’: 1, ‘PropertyList’: {‘Power’: False}}), nothing happens. The LC7001 seems to filter out such requests if it it thinks (erroneously) that the light is OFF already. So is if it’s possible to send  some kind of a force command that ensures the LC7001 sends a message to the switch independant whetehr it’s OFF already or not?

PS: The same problem happens on the Android App. So if the OFF command fails, the App still shows it as OFF while the light remains ON in reality. I then need to turn it ON again via the App before I can turn it OFF a second time.

Hi Michael,

Thank you for your interest in our local API.  As you correctly observed, the LC7001 commands to the endpoints can sometimes not make it to the endpoint.  This can be worse for endpoints that are farther from the LC7001.  One way to address the distance problem is to buy a MRR2-G repeater for your system and place it somewhere in your house that is half way between the LC7001 and the farthest endpoint..  That should make it much more reliable.  I would suggest that route before trying to re-send each command from your software since, as you mentioned, the LC7001 will not allow duplicate commands.  Is that an option you would consider?

Thanks,

Doug

Doug,

Thanks for reverting. I would consider that option, but I’m not convinced it will solve all my problems. All my 20+ switches are less than 30ft (10m) away from the LC7001 (Spec states 100ft!). So it would be nice to also have the option resend the latest command a few second later again. Is that possible?

Thanks

Michael

Hi Michael,

Currently the LC7001 does not support a way to resend the same command twice in a row.  I will check to see if there is anything we can do.

Thanks,

Doug

Thanks for checking. That would really be a great help for me if you could include such a feature in the API.

I got myself a MRR2-, and the situation has somewhat improved. But I had again yesterday a situation where a switch just 10ft away from the LC7001 ailed to receive a command. So I would still like the ability to force resend an OFF command.
