@EricM_Inovelli could you provide some clarification on what the following enhancements mean?
- Changing minimum level to 10% to accommodate likely use of LED bulbs.
- Adjust maximum brightness to 85% to prevent the dimmer from shutting off.
Does this mean I cannot set the dimmer to full brightness, and if not, could this cause issues when using smart bulbs + disabled relay (since smart bulbs are not typically designed to be dimmed)?
The first item is just changing the minimum level default from 1 to 10. Most people are using LED bulbs which usually don’t turn on at lower levels. The result is the user turns the switch on and it takes a long time to ramp up from 0 to whatever percentage it turns on at (my experience is usually even after 10%). So this is to help with those customers that don’t set the minimum level themselves so it doesn’t seem to take so long to turn on.
The second item actually shouldn’t be there. It was from an earlier beta where the manufacturer tried to come up with a quick fix, but it was reverted. I just forgot to take it out of the notes. The dimmer should output the full voltage at 100%.
Probably against the rules posting this and you probably already know about this, but… Why not do something like this instead? Fibaro Dimmer 2
Dimmer 2 is equipped with an algorithm of smart light source detection. Depending on the connected type of light source, it automatically adjusts an optimal control mode (leading edge for inductive loads, trailing edge for capacitive or resistive loads). The procedure of learning the light source type is called calibration .
During the calibration procedure, radio connection is disabled and the Dimmer 2 does not respond to any commands. It may cause temporary problems with communication in the Z-Wave network. After completing the calibration, communication with the module will be restored.
Calibration automatically adjusts maximum and minimum light levels (parameter 1 and 2). However, the installer is obliged to verify the proper operation of the device, according to control modes description. There is a 10% probability that calibration settings will require a manual correction. In a 2-wire connection for loads other than resistive parameter 1 settings must be adjusted manually.
Calibration procedure is performed always after removing the device from the Z-Wave network. If the device is not included, after each power on/off calibration will occur. For the included device, calibration is performed in accordance with the parameter 35 settings.Some types of LED and CF lamps are designed to operate in leading edge mode (with conventional dimmers). Information about proper operation mode of the bulb should be included in its manual. In this case you have to manually force the desired operating mode using parameter 30.
After changing the load launch the calibration or remove and add the device. Before changing the operating mode or performing the calibration procedure the light must be turned off. Verify the operating mode, according to product documentation.

This might be possible in the next series of new switches but for now there isn’t enough storage in the MCU to add anything new for now.
For those having problems getting the PC Controller program here is a link to it.

im excited to see this. I saw that you had a new firmware that would keep the notifications persistant which is going to be awesome! Thanks! ill try to get this implemented in my social distancing forced free time

When the new stable firmware is released, will any purchase of the dimmer switch made on amazon.ca be with the new FW already installed? From other posts I read on this great community forum, in order for me to upgrade my current red series dimmer, I will require a Z-Wave USB stick with a computer. I am using SmartThings.
Thanks
Justin
Hey @Grosbiz - great question! No, unfortunately the stock at Amazon.ca still has the old firmware on it. But any new switches produced will have the updated firmware
This is correct… for now… wink, wink. That’s all I can say lol.

@Eric_Inovelli - Add me to that wink wink device if beta testers are needed. Otherwise I’m waiting until Hubitat allows OTA. Too much work to (exclude, include)^2 so many switches.
Any timeline for Smartthings to have the OTA firmware update capabilities?
-Richard
I’m afraid it’s not our device otherwise I would lol!
I wish I knew the answer to this, but this was what my wink, wink was referencing

You mean not your device YET…I’m sure Samsung will sell it to you.
I’d love more than anything to have more support tickets come through and more forum posts to respond to lol /s

Thanks for your quick answer.
Note for Home Assistant people, you can shut down your HA machine, grab the zwave stick, plug it into you computer, and do the firmware update without all the “remove/add” steps.

Nice to know. I did all the removal stuff anyway, firmware upgrade went well using my HUSZBZ-1.
Glad I found this update after only installing one switch. Ill make sure to do each before I put them into service.
I finally got the controller up and running now I am trying to figure out how to update my switch without bricking it. Does anyone use the Aeotec Z-Stick Gen5?..What must be done to keep it from flashing?..Do you need to press the button to make it work? It does show up in the Controller App…thanks…
Hey @neutronspin - I actually use Aeon’s Z-Stick at work. It works great! I haven’t figured out all the random blinks it does, but it works fine.
If it shows up in the controller, you’re all set. Just follow the directions in the link in the first post above and you should be good.
Happy to help further if needed!
Just updated the firmware on one device and it works! A little learning curve but your instructions were spot on. The only problem was getting the software from the Z-Wave vendor…a little convoluted but it works fine. I am going to wait until I update the rest of my dimmers. It would be easier in my Hubitat hub to exclude it from the hub using their exclusion first then include it on the Z-wave stick then update the firmware and remove it from the stick network…if that makes any sense…
It would be nice if Hubitat would add firmware update on their hub but…I may wait updating the firmware on my other dimmers until I ditch my Hubitat hub for a mystery new hub…lol:sunglasses:
