Gas Detector

inetjnky · October 3, 2022, 5:55am

I have a Heiman Zigbee Natural Gas Detector in my furnace room to help detect a natural gas leak. One of the things I'm noticing when I'm writing my rule is that it's showing the clear status as "False" even though it's currently in the clear state. Any idea why this wouldn't be true?

Here is the Rule:

Thanks

There are 2 states for rules. True and False. In your case you're saying that if gas is detected do what ever. Well gas is not currently detected (it's clear) so that portion of the rule is false so there is nothing for it to do. If you get a gas leak and your sensor goes off, that will turn to true and continue with the rest of the rule.

I dunno about you guys but my detectors (wife and daughter) are usually are quite animated when gas is, um, detected.. usually after a hearty meal.

Blame it on the dog we don't own...

(apologies for silliness)

Yes but the second if should be showing as true.
Try changing the condition to use a custom attribute instead and manually select naturalGas? Is the built in feature using the wrong attribute maybe?

Ahh dammit didn't see the second false

That’s what I was alluding to.

Based on the wording of the rule I think it might be looking for an attribute named "gas" not natrualGas as shown on your device. Is that a built in driver or a custom?

Are you updated to current hub FW? I know saw some talk about this device in beta and/or release notes. I don't use anything like this so I was not paying attention to it.

Have you tried making it using the Custom Attribute option instead? I suspect that will work. You may need to do it on the trigger and both If conditions.

I believe that the HE people recently changed the driver for this device.
Make sure that you have the "new" version.

I would also like to suggest that an easy way to do this detection is through the custom monitoring in HSM. (This was recently fixed for the Heinman Gas Detector - I've tried it and it now works.)

How does one get the new version? I'm running the latest firmware.

The following screenshot is from the latest driver:

Note how it has the gas state.

change the existing driver to "device", and execute the boxes the delete all previous states, etc.
change the driver to "Heiman zigbee gas sensor", and hit configure.

(Note you have to be on the latest version for this: 2.3.3.x)

Thanks, I just added your driver and will use this one. Appreciate it!

inetjnky · October 3, 2022, 7:53pm

Went back and used Custom Attribute for the entire rule.

Looks much better.

inetjnky · October 3, 2022, 7:54pm

I just wish I could buy one more of these devices for behind my gas stove. Can't find them anywhere.

kahn-hubitat · October 3, 2022, 8:01pm

My driver also alerts smoke as well so you could use it in the past before naturalgas was a capability.
