    No Local Hub Processing When Offline HUGE BUG/FLAW

    You have got to be kidding me. No, you aren't. I tested this and no alarm with disconnected Internet.

    First Alert Zsmoke chirping at less than 77%

    A smoke detector shouldn't be chirping at 1.39VDC. I think the smoke detector's low voltage chirp threshold is too high.

    First Alert Zsmoke chirping at less than 77%

    It seems that Iris handles the smokes just fine. The Detector itself doesn't handle itself properly. I tested the batteries and the low battery chirp comes on way before it should. FirstAlert couldn't quote what the low voltage warning should activate at, but without question they replaced the detector. I've had a few false alarms from various Zsmokes from FirstAlert. I want to try rechargeable alkalin batteries in these. NiMH won't cut it.

    Any news on the new hub?

    My early 2013 hub just folded. 5.2V at the plug and no lights. I happen to have a Vera3 lying around and alot of Zwave devices. I wonder if I can convince them to give me a new hub.
  5. Push notifications to the Iris app, which rolls back locally stored audio clips of the system sounds over the phone's speaker: System door chime, doorbell, voice annunciations...

    Remote Speaker

    I think the keypad is too simple of a device to make voice announcements. If Iris was really on top of their game, push notifications to mobile devices could roll out system sounds from your mobile device speakers, including door bell and door chime.
  7. Has anyone considered adding a higher-gain omni to the hub? My coverage pretty much sucks on Z-wave. I have my hub mounted on the center of my livingroom ceiling, if I put a range extender any further away than this room I lose Z-wave connectivity and get red bars on Zigbee.

    Iris Door Chime Feature

    I kinda want to hack into the speaker on the Iris hub and add external speakers.

    Yea, its Wifi based control.
  10. I have two 80 gallon indirect water heaters connected to a closed loop solar system. They have auxillary 3.5kW electric heaters in each with standard water heater thermostats and high limit switches. The plan is to buy two 20A contactors, and use the 120V switched power from a smart-plug to pull in the contactors. I'll schedule smart-plug to turn on in the evening near the end of the solar harvest to make sure the storage temp reaches the electric heater thermostat set-point of 145F. Once they reach set-point I think I can program the smart-plug to shut-down and wait for the end of the next day to kick in. The electric thermostats are at the middle of the tank, while the indirect coils are near the bottom. So its very likely that the smart-plug will energize at the end of the day and there won't be any demand for electric heat from the thermostats. I was thinking about hacking a contact sensor to use an aquastat contact that watches the top of the tank temperature, but darn if aquastats are so expensive.
  11. Greetings all, I just purchased these batteries and a charger from Amazonians: The rest fully charged at 3.35V (which makes them about 3V nominal), compared to most other lithium ion cells that operate at 3.6V nominal (4.1V resting fully charged). The cool thing is that at 2 for $8 they are cheaper than most primary CR2 batteries, and have a similar capacity rating to CR2 primaries at 800mAh. I have two of my six installed. One is in a "high traffic" contact sensor that is actually a flow swich on my hot water system, that is reporting contact status from a flow paddle switch on the cold water inlet to the water heater, and the temperature sensing chip is heat-sinked to the hot water recirculation return pipe to function as a demand response aquastat. with the dynamic temperature readings and dozens of contact cycles per day, it eats up CR2s a bit faster (6mo tops). I'll let everyone know how it performs but I expect with their very low self-discharge chemistry they should perform well.

    First Alert Zsmoke chirping at less than 77%

    Further testing has revealed this repeatable data using the same batteries. 1.39V per cell in an old 2013 Zsmoke makes 76% battery level and causes low battery chirping. 1.39V per cell in a new replacement Zsmoke makes 83% with no chirping.

This data above is from a test with some really dead batteries in an older Zsmoke, 1.25VpC. I have two good DMMs that are both in agreement on voltage within 0.03V. I just installed the 1.39VpC 76SoC% chirping batteries into the replacement Zsmoke from First Alert technical support, and it is now showing 83%: {"id":"AD-05-00-C8-17-75-88-2D","name":"SMOKE UPSTAIRS GUEST","type":"FirstAlertSmokeAlarm","typeId":"42096","protocol":["zwave"],"isZwave":true,"isGeneric":false,"version":"0.5r0","latestVersion":"VERSION_UNAVAILABLE","hardwareRevision":"0.0","channels":{"presence":true,"battery":4.66,"batteryPercentage":83,"batteryLevel":5,"signal":100}}, Note the version 0.5r0 on the newer Zsmoke? Hmmm very interesting. It seems to be scaling the battery voltage differently.

    First Alert Zsmoke chirping at less than 77%

    Tested a 1.26V used alkaline fand Iris reported this smoke detector as 1%.
  15. I have a rather large fleet of First Alert's zsmoke detectors, and one zcombo associated with iris. I've had several start chirping within a few months of purchase and popped new batteries in, and just now have started investigating what seems to be a premature warning from the smoke detector. First Alert technical support was helpful, I tested a detector that shows 77% on Iris status and was chirping low battery at 1.390V per cell on the OEM Duracell batteries. 1.390V seems too high to be a low battery, although a new Alkaline starts at 1.600. They shipped me a new zsmoke no questions asked (didn't even ask for a return of the old unit). I am going to put these 1.390V cells in the new detector that was sent to see how it responds. First Alert was unable to determine what final voltage the detector is looking for the low battery chirp or the voltage span for the percentage, but the percentage indicated seems to feel accurate for an alkaline span. Any similar experiences?
