In the ISY at the bottom of the screen for the Keypad you find an option for adjusting the KPL led backlight. You can set the brightness for both the on and off levels.

You may have to add a resistor in series with the 5v supply. I had a similar issue, the resistor resolved it. Take a look at this post. http://forum.universal-devices.com/topic/8882-new-insteon-wireless-thermostat-2441zth-us/page-6?hl=resistor&do=findComment&comment=81700

If you're going to use them again next year why not disable the devices in the ISY then unplug them, The scenes and programs would remain intact.

Try removing power from both the PLM and the ISY then power up the PLM, wait 10 seconds then power up the ISY.

It's possible that the meter is interfering with the Insteon signal. Do you have any dual band devices and/or access points installed. If not you may want to add access points to improve the Insteon signal ( assuming that the 99i will support them)

In addition Paulbates's comment, have you recently added any new devices? The now discontinued 99i does not support some of the newer modules. The problem could also be caused by interference from electrical devices. Have you added any new electronics? Do you have any CFL bulbs, if so the ballasts sometimes go bad injecting noise into the power line which can interfere with the Insteon signal.

Possibly a bad XXX What is XXX?

k5map, If you want to adjust the on and off levels of the KPL backlight you could do it in program. This affects all the buttons on the KPL. This program dims the backlight at Sunset and brightens it at sunrise. If From Sunset To sunrise (next day) Then set 'KPL name' On 3 / Off 2 (Backlight level) Else Set 'KPL name' On 8 / Off 2 (Backlight level)

Mine shows a change as small as 1 degree. It's possible that there may be a delay in the thermostat reporting in order to prolong battery life.

If you're in the planning/building stage be sure to have your electrician install a neutral wire in each switch box as the Insteon dual band devices require both a hot lead and a neutral in addition to a ground.

You could use the wireless Insteon thermostat with a battery eliminator power supply. You could then write a program to have the ISY email you if the temperature and/or humidity reaches a programmed threshold.

Seems the biggest reason for the Insteon device failure is caused by black outs/brown outs and power surges . It's best to add a whole house surge protector at the main panel(s) especially if you're located in an area that has an unstable power grid.

If you use a program to turn on your applianceLinc based on temperature you won't have to worry about setting heat/cool points and/or modes in the thermostat. I've replaced batteries in my thermostat and it came back online without any button pushes, etc. Not sure what happens if you're using "mode" to control your applianceLinc. It's possible the thermostat may revert to off as a safety measure. Guess you could pull the batteries then put them back in to see what happens.

Try a factory reset on the thermostat, it's possible something in its memory got corrupted.

The mode setting is a moot issue as you're only monitoring the temperature changes. The temperature and humidity will update in the ISY regardless of what the mode setting is. My modes are all set on off. If the tstat looses power it should resume sending data when the power is restored.

How about the Insteon motion sensor with a battery eliminator power supply, and you wouldn't need the IOLinc.

gatchel, Pick up a circuit tester at a hardware store, it tests for correct wiring, open ground, reverse polarity, open hot, open neutral, hot on neutral, hot and ground reversed with open hot in 3-wire, 125VAC circuits. (see attached). These are good to have around as many outlets are incorrectly wired, but your current problem does sound like a loose neutral connection.

416to305, Both incandescent and halogen bulbs are based on the concept of two parallel metal wires transmitting an electrical current to a tungsten filament that connects them, heating the filament to a point where its heat is reflected as light. The major difference between an incandescent bulb and a halogen bulb is the gases that each produces within its glass bulb. The purpose of gas production is the same in that it is meant to slow evaporation of the filament and keep it from rusting. Both incandescent and halogen bulbs go dark when the filament wears out and breaks. Incandescent bulbs fill with a mixture of 93 percent argon and seven percent nitrogen, both of which are inert gases. A halogen bulb adds a halogen gas, such as iodine or bromine, creating a chemical reaction that regenerates evaporated tungsten and puts it back on the filament, helping to extend the filament’s life and therefore the life of the light bulb. In theory both should work with the two wire RF only switch, however an led light does not supply enough voltage to the switch to power it.

hart2hart a query will not provide temperature or humidity. the only time temperature and humidity will be updated in the ISY is when one of the values on the thermostat changes. I have several 2441ZTH's, one I use to turn on the bathroom exhaust fan when the humidity exceeds a predefined level, I use another to turn on an exhaust fan in an equipment closet when the temperature exceeds a set level. If you want to force the thermostat to manually update in the ISY blow hot air on it.

Try doing a factory reset on the IOLinc then reinstalling it. Seems everything else is correct.

If you have a power supply hooked up the thermostat you should be able to query the device. If it's only battery powered then the query will not work as the device sleeps until either the humidity or temperature changes. However if powered by either battery or power supply the temperature and humidity will not update or populate the ISY until one of the parameters on the thermostat changes

Are you sure that the IOLinc is communicating with the ISY? Do a device query to make sure. Have you set up a program to turn on the light when the sensor is triggered?

Is the light included in any programs or scenes, if so try disabling the program(s) to see if that resolves the issue. What type of device is controlling the light?

I replaced all my ApplianceLincs with the newer dual band on/off modules which are more reliable and I have not had any issues.

The dual band On/Off modules do not have load sensing and will work with the LED lights
