Hi all, apologies if this is the wrong place to post this…I’m new here…
Anyways, I’ve got an old Lutron Homeworks Series 8 system installed and I’ve managed to integrate it into Home Assistant using this integration: Lutron Homeworks - Home Assistant.
I’m using a Moxa NPort Serial to Ethernet adapter connected to the Homeworks processer.
When I first start up HA, everything works fine. Lights turn on and off and everything functions like normal. After a while (the time varies, sometimes it’s 10 seconds, sometimes it’s 10 hours) the Lutron lights stop responding in HA. The keypads and physical dimmers still work fine, but when a light is turned on either via HA or a physical switch, HA does not update that light so it remains “off” in Home Assistant. Other devices still work fine in HA. Only Lutron lights stop responding.
Sometimes HA can still control the light (ie dimming and turning on) but the light is stuck in the “Off” position on my dashboard & everywhere else in HA, so I can’t actually turn it off from Home Assistant. Other times, HA cannot control the light or see its on/off status.
I’m running Home Assistant 2021.11.0 on an Intel NUC as HomeAssistant OS. (ie, not through docker - the NUC boots into HA & has nothing else on it)
This also happened when I was using a RasPi 4.
Does anyone know how to fix this so the lights update reliably?
UPDATE: For anyone who might stumble across this later, I was able to fix the issue! On the Serial to Ethernet Adapter, the flow control needed to be set to DTR/DSR in order for the integration to work. After fixing that and restarting HA, everything works flawlessly!
@ghersh thanks for updating your post since it helped me with a similar issue. I’m curious have you been able to use the integration to get your keypads working? My dimmers work perfectly but I can’t figure out how to make the keypads work. I have added a keypad and I can see events firing in the Developer Console but I don’t know how to take that information and simulate a button press on the keypad.
Oh, glad I found this thread. Does anyone have any documentation or know how to wire up an RPi to the Lutron Homeworks (Series 4) multidrop serial device busses?
I have a system that has a number of SeeTouch wall buttons (with up/down dimmer buttons) and a bunch of WPMs in the walls. How do I interface the new Pi with the old Homeworks?
Sorry for replying to such an old thread, but I’m having a similar problem, but I’m not sure it’s the same. I’ve tried every setting on the Moxa to get it to communicate both ways, but it continues to only update from HA->Lutron.
I have the Moxa set to TCP Server Mode with local port 4001 and command port 4001 with my serial port on DTR/DSR (per your above). My config YAML file has the following:
homeworks:
host: xxxx
port: 4001
Everything connects when HA boots and I can control from HA → Lutron, but I don’t get anything back from Lutron->HA. All the lights show as “off”.
Would you mind sharing any differences in your config? I so appreciate the help. HA has been awesome for me, but I would LOVE to be able to get Lutron to update both ways.
Hi,
Is there a reason that the Homeworks integration only uses RS232 instead of the available ethernet jack on the processor? I don’t have an available serial to ethernet adapter and was hoping to connect directly to the processor through the RJ45 jack. I tried updating the configuration.yaml file and also tried creating a “custom integration” but neither seemed to work. I’m not sure if this thread is the proper place for this question, but any help would be appreciated.
I also have a large olderer Lutron Homeworks Series 8 system installed and I’ve managed to integrate it into Home Assistant using this integration: Lutron Homeworks - Home Assistant .
I’m using a Moxa NPort Serial to Ethernet adapter connected to the Homeworks processor. I am not seeing any of the keypads listed as entities. Lighting loads do show. Just curious if someone has ever been able to get the keypads to show. I can create a button but without the entity I am in the dark here. Have about 40 keypads to enter.
