I’ve had this working for quite some time using the new custom_components. I don’t think a PR was ever made. It’s working in 92.1 for me.

UV water treatment offers many advantages over other forms of water treatment for microbiological contaminants. Most importantly, it does not introduce any chemicals to the water, it produces no bi-products, and it does not alter the taste, pH, or other properties of the water. Accordingly, in addition to producing safe drinking water, it is not harmful to your plumbing and septic system. Furthermore, it is easy and cost-effective to install and maintain without any special training. Trojan Technologies, manufacturer of the Viqua (Trojan) UVMax line of household ultraviolet sterilizers, and R-can, which makes the popular Sterilight brand of UV sterilizers, are pioneers and world leaders in the field of UV water treatment. These companies even manufacturer large UV sterilization systems that can be used by municipalities and regional water districts for large-scale water disinfection. How UV Works Ultraviolet purification uses a UV light source (lamp) which is enclosed in a protective transparent sleeve (usually quartz). The lamp is mounted such that water passing through a flow chamber is exposed to the UV-C light rays. When harmful microbes are exposed to the UV rays, their nucleic acid absorbs the UV energy, which then scrambles the DNA structure of the organism. The cell is rendered sterile and can no longer reproduce. The cell is now considered dead and is no longer a threat. Applications UV treatment is an excellent choice to eliminate biological contamination from most home drinking water, whether your home is on a municipal water system or untreated private system (well, lake water, etc.). Its sole purpose is to kill harmful biological contaminants, and therefore should always be combined with other forms of filtration (GAC / carbon block, KDF, or reverse osmosis) for reduction of heavy metals, chlorine, VOC's, and other chemical contaminants. What Contaminants Does UV Remove? There are no micro-organisms known to be resistant to UV, unlike chlorination. UV is known to be highly effective against bacteria, viruses, algae, molds and yeasts, and disease causing oocysts like cryptosporidium and giardia. In practice, bacteria and viruses are the cause of most major waterborne pathogenic diseases. Of these enteric viruses, hepatitis virus and Legionella pneumophila have been shown to survive for considerable periods in the presence of chlorine, but are readily eliminated by UV treatment. For most microorganisms, the removal efficiency of UV for microbiological contaminants such as bacteria and viruses generally exceeds 99.99%. Specifically, the following are moved to an efficiency of greater than 99.99%: E-coli, Salmonella typhi (Typhoid fever), Salmonella enteritidis (Gastroenteritis), Vibrio cholerae (Cholera), Mycobacterium tuberculosis (Tuberculosis), Legionella pneumophila (Legionnaires' Disease), Influenza Virus, Polio Virus, and Hepatitis A Virus (better than 90%). Countertop UV systems are generally not recommended for removing oocysts such as giardia and cryptosporidium unless equipped with a 0.5 micron carbon block pre-filter since the exposure time the contaminant has to the UV ray is not always long enough to provide an adequate UV dose for disinfection of these more complex organisms. Whole house UV systems like the Trojan UV Max on the other hand, are capable or killing waterborne oocysts at household flow rates when a properly sized model is selected for the application.

UV lamp performance, just like any other light source, will slowly diminish over time. Beyond one year, there is no assurance that the UV light emitted from the bulb will provide sufficient disinfection. Remember, UV light cannot be seen. The bulb may still produce light, but not necessarily UV rays. The quartz sleeve does not need replacement unless it gets broken, however, it should be cleaned several times per year (outside only). Frequently Asked Questions About Ultraviolet (UV) Purification What is UV? Ultraviolet (UV) light is at the invisible, violet end of the light spectrum. Even though we can't see UV light, we are exposed to UV rays from all light sources, including the sun. How does ultraviolet light purify water? UV-C rays penetrate the cells of harmful bacteria and viruses in our drinking water, destroying their ability to reproduce. Without this ability, these organisms die and no longer pose a health threat. It is a simple but very effective process, with the system destroying 99.99% of harmful microorganisms. Why not use chlorine instead? Chlorine changes the taste and odor of water. Chlorinating also produces harmful by-products called Trihalomethanes (THMs) which are linked to incidence of cancer. Does a UV system use a lot of energy? No, the UV unit will use about the same amount of energy as a 60 watt light bulb. It is a cost effective, natural way to increase water quality. Why do UV purifiers require sediment pre-filtration? UV systems require pre-filtration to maintain effectiveness as sediment and other contaminants in the water can create a "shadow" which prevents the UV rays from reaching and disinfecting the harmful microorganisms. How often does the UV light bulb (lamp) need to be replaced? It is essential that you change your UV lamp annually. The ability of the lamp to emit UV light decreases over one year in operation. Remember - UV light is invisible! Even though the lamp is still glowing after one year, there might not be enough UV light reaching your water to be effective. How often do your need to replace the sleeve? The sleeve doesn't need to be replaced unless it is broken, but it will need to be cleaned several times a year in order to keep the bulb effective in delivering high water quality.

Some vendors offer more realtime APIs, even Ring uses a websocket based API for their alarm sensors which lets me trigger events in near real time from alarm devices, but the API for doorbell/camera is still old school polling (their app works the same, it just fakes the status probably by updating the local state machine immediate or something until the next poll interval, but if you turn on the light with, for example, HA, while watching it in the Ring app, you will see it take seconds before the new status is reflected there, because of this very same polling.

Check your “States” under Developer Tools, it should be named “light.device_name” where device_name is whatever you have it named in your Ring app. It should be called the same as your camera,

here is what I see. I also see the preview of the cameras on the main page. I see all three of my camera’s but no light switch option.

HA Floodlight Button = OFF (WITHOUT any user toggle—button state seemingly changes itself to OFF just moments later) AND Floodlight Physical Light = ON (light still ON via original HA Button user toggle)

FYI, as of 0.97.0 some minor adjustments need to be made to get this to work. Is this in a repo anywhere that I can submit a PR?

No, I don’t mind at all! I just never had time to jump through the hoops to get it merged in. Got too busy. But I’d love to see it make it into the main home assistant stuff.

HA Floodlight Button = OFF (user toggled) AND Floodlight Physical Light = OFF (light turns OFF via this LATEST HA Button user toggle)

You haven’t broken your configuration.yaml up into separate files have you? Otherwise, I don’t see anything wrong with the configuration. That’s basically what I have and I get lights for both of mine.

Does this Ring light platform require a Ring Bridge to be installed, or can it be controlled via Home Assistant directly without needing to authenticate with Ring’s cloud?

I believe that all operations need to go through Ring’s cloud. I have no idea what the Ring Bridge is, there’s nothing on Ring’s website about it that I can find. Perhaps you’re referring to the security base station?

I could be wrong, but I don’t think there’s much that can be done about this because, unfortunately, the Ring API for controlling doorbells/cameras/lights is 100% polling based. This means that HA has to poll Ring servers at an interval to get device state and update the internal state machine. As written, the code polls every 10 seconds, although the Ring API can sometimes be quite sluggish responding as well.

HA Floodlight Button = ON (WITHOUT any user toggle—button state seemingly changes itself to ON just moments later) AND Floodlight Physical Light = OFF (light still OFF via the LATEST HA Button user toggle from #5 directly above)

So earlier in the thread @tsightler and @claytonjn helped me get my Ring Floodlight’s on/off light controls working within my Hassio on Pi setup.

Now, there may be some things that could be done, I don’t really know that much about how HA plugins work, perhaps you could force an immediate poll whenever button is pressed. Someone with more knowledge of the HA framework would have to answer that, I can just say I see this with other components as well and I just wait for the state updates.

The Ring Bridge lets you group together Ring Smart Lights and connect them to Ring doorbells and cameras and select Alexa-enabled devices via the Ring App.

However, when I say “(mostly) worked” above, there’s an oddity I’ve had since day 1, and continue to have today (below is a GIF, so it may take a moment to load on your end): ring-floodlight-HA-issue-GIF_3702×1248 2.9 MB

Note that while I’m using HomeKit/Home.app (where I have this on/off button forwarded via Home Assistant) in my GIF example above, the same exact issue/behavior occurs directly within Home Assistant when I toggle the Ring Floodlight on/of directly within HASS.

My configuration.yaml has been broken up into lots of files for at least a year and I’m running HA 0.102.2. The only thing I can think of is that I have a custom component for Lutron lights that may be interfering?

The Ring Bridge is for a completely different product set. This is purely for Floodlight Cams and Spotlight Cam products that don’t require a bridge to work.

UV lamps (bulbs) require annual replacement to ensure optimal performance. UV lamp performance, just like any other light source, will slowly diminish over time. Beyond one year, there is no assurance that the UV light emitted from the bulb will provide sufficient disinfection. Remember, UV light cannot be seen. The bulb may still produce light, but not necessarily UV rays. The quartz sleeve does not need replacement unless it gets broken, however, it should be cleaned several times per year (outside only).

Once started up, I see the floodlight camera, binary_sensor, and sensor entities all show up in the device state list, but the light entity is not appearing.

HA Floodlight Button = OFF (user toggled) AND Floodlight Physical Light = OFF (still OFF via the LATEST HA Button user toggle from #5 above; essentially back to “default” state originally described in #1 above)

yea, like I mentioned, I see the floodlight camera, binary_sensor, and sensor entities in the device state list, but the light entity is not appearing.

I hadn’t realized that, but now I’m waiting on the HA button to let it restore itself to the correct state, and it’s indeed working.

Ultraviolet water purification lamps produce UV-C or "germicidal UV", radiation of much greater intensity than sunlight. Almost all of a UV lamp's output is concentrated in the 254 nanometers (nm) region in order to take full advantage of the germicidal properties of this wavelength. Most ultraviolet purification systems are combined with various forms of filtration, as UV light is only capable of killing microorganisms such as bacteria, viruses, molds, algae, yeast, and oocysts like cryptosporidium and giardia. UV light generally has no impact on chlorine, VOCs, heavy metals, and other chemical contaminants. Nevertheless, it is probably the most cost effective and efficient technology available to homeowners to eliminate a wide range of biological contaminants from their water supply. Recent testing has also shown that UV can be effective at destroying certain VOC's, although we would not specifically recommend the technology for VOC reduction. UV water treatment offers many advantages over other forms of water treatment for microbiological contaminants.

So what happens, when you hit the button, the switch toggles and sends the command to Ring to turn on the light so that happens quite fast, however, the state machine still thinks the switch is off and will not be updated with it’s new state until the next polling interval so the visual effect is you see the switch toggle, and then quickly toggle back.

I see this exact behavior with the Tuya cloud component as well and it’s been described many times on other posts. Typically, if you wait at least the time of the polling interval (or, on average, about half the polling interval) then the switch should be updated to show the correct state.
