Can Smartwares RM174RF smoke detector support be added in Domoticz?

[tomson]

Hi all,

It was time to replace my Alecto SA-30 smoke detectors with newer ones. I decided to go for the Smartwares RM174RF due to the fact that they can be linked (which nearly all Zwave detectors cannot). Furthermore, I did check that the RFXCom was supporting them.

However, I did not check if the device was implemented in Domoticz

Domoticz can recognize that the device is sending a panic message, but does not recognize what kind of device it is.
I have found similar questions about the support of the RM174RF, but not under the Rfxcom receiver. Hence, I created a new post.

The rfxmngr is detecting the smoke detector as expected.

Code: Select all

------------------------------------------------
17-6-2019 09:04:48:866
Packettype    = Security1
subtype       = RM174RF smoke detector
Sequence nbr  = 126
id1-3         = 1E8733 decimal:2000691
status        = Panic
Signal level  = 7  -64dBm

The RM174RF is quite cheap. Is there any chance that this will be implemented in Domoticz?

Hi,

As long Domoticz does not support your smoke alarm, you can implement it probably with node-red. If you have node-red installed you can use rfxcom node, which supports detector and alarm devices. However devices on 433 MHz are not intended as life safety systems.

Thanks for your reply with the node-red suggestion.

Although it has been ages that I did any programming, I looked a bit at the source code of Domoticz on GitHub. I think I should be able to extend the code of e.g. the Alecto SA-30 smoke detector and implement the RM174RF. It's at least a good learning experience.

The Alecto SA-41 and SA-43 are very similar to the RM174RF. If anyone can add the subtype passed through by the RFXCOM, I might give it a stab to add the SA-41 and SA-43 as well at the same time. For example, the subtype of the RM174RF is subtype = RM174RF smoke detector.

No guarantees of any timeline and positive outcome

Hi,

You may want to look at the latest beta, 4.10935, as a fix for the RM174RF has been committed.
See: https://github.com/domoticz/domoticz/pull/3343

I am testing this at home. gizmocuz finished off the pull request I did. I should have changed the code in more places than I did. Big thanks for gizmocuz (as usual )

Currently with 4.10935 Domoticz is able to detect the panic function of the paired smoke detectors. I am not able to trigger a panic from Domoticz. According to the RFXCom manual I should be able to send a panic function. I will need to do some more testing/investigation to see what is going on.

Overall, how do you rate those detectors?

I have not installed them yet, but prefer the size and looks over my old Alecto SA-30. Another advantage is that they only use two penlite batteries (and not three penlites + one 9v battery in the SA-30).

Before I bought the RM174RF, I did purchase two Fibaro FGSD-002. They look much better, but for the same price one can buy four RM174RF's(!) The fact that I could not link the Fibaro ones was a deal breaker for me, because I want to use four smoke detectors on three different floors in my house. Furthermore, it is also impossible to trigger the Fibaro ones from Domoticz.

I also looked at the POPP POPE004001, which is a linked Zwave smoke detector that has an alarm that can be triggered as well. Functionality wise this is the winner. The price point is around the same as the Fibaro. I did not really like the looks and total investment.

For me the RM174RF was the clear winner because of the combination of price, looks, fact that they can be linked and triggered (according to the RFXCOM manual). The only thing remaining is to get the triggering actually to work in Domoticz

The Alecto SA-41/43 is very similar to the RM174RF, but please beware that this one uses the Origon protocol (vs Arco Pro / lightning 4). (Alecto requires firmware 1 of RFXCOM and the RM174RF requires firmware 2). The Alecto SA-41 is not implemented at all in Domoticz.

I hope this info helps.

[EdwinK]

Yes, thanks it did.

Ordered them and they will arrive tomorrow.

[EdwinK]

So, they have arrived, been paired and found in Domoticz, now trying to figure out what of the many panic devices to add. For two smoke-detectors I have, there are 16 devices created.

[tomson]

I got more devices as well. I assumed this happened because of the pairing process when one of the device get in a kind of broadcast mode. I just restored my DB and re-added the already paired devices. Now I only have one. Does that work for you?

[EdwinK]

No, didn't work

[EdwinK]

Removed all instances of the detector and let domoticz find them again. Now i've only 3 devices show (still one too many), but.. cant trigger them from the dashboard.

> The only thing remaining is to get the triggering actually to work in Domoticz

I was not able to trigger them either (like I tried to describe with the sentence above). I have not had time to investigate more and compare the behavior with my old SA-30s from Alecto. I did notice that when pressing the "panic" button, the status of the device does not change to panic in Domoticz. I will check that behavior with my old SA-30's, but did not have the opportunity yet (it will make a lot of noice).

Hey guys,

I have been using my Domoticz raspberry 2B with RFXCOM transceiver for a couple of years now. I mostly use it with COCO solutions.

But now I like to extend with other solutions: smoke dectectors. I have a couple offline cheap detectors hanging around the house, most have broken down. So I am looking into 433 Mhz capable detectors.

But I don't seem to find the answer to a simple question? What kind of data do the dectectors send to domoticz?
1. Alarms => the minimum minimorum, seems logical
2. Battery-level? => this is key: The main reason offline detectors don't get replaced is because batteries run down at the most inconvenient times. I would like to receive warnings or monitor their battery levels from domoticz.

Does this RM174RF detector provide battery level? (I can't if zwave solutions have that functionality either)

thx,

Theo

These sensors do not transmit a battery low status

Hi,

Just received 3 pieces of the Alecto SA-41, if you buy them in a package of 3, their name wil be SA-43.
So basically the SA-43, are just 3 pieces of the SA-41.

It is NOT compatible with the SA-3x series, it will use a different protocol.
Have tested these items with the RFX-Com connected to the computer.

Firmware Ext. 2 (1025) does detect them as Smartwares RM174RF
Firmware Ext. or Type 1 does NOT DETECT them.

Strange thing is that I coupled all devices as stated in manual.
After this I go to the Switches page in Domoticz and select the Learn option, shortly pressing the button on the device (like the test procedure in manual).
2 of the devices showed up as expected. When 'Learning' the 3rd device it comes up that it is already known under one of the other devices.

Think this could have something to do with the pairing process.

Also I'm not able to trigger the panic function at all, not from domoticz, but also not from the RFXmngr software.
Please be aware that RFX Com site mentions the protocol be Oregon fot the SA-4x serie, this however is not correct.

Kind regards,

Thijs

I ran into the same issue with the SA-41 on the ProXL1 1048 firmware. It's detected as RM174RF.

According to the manual the RM174RF can only be received by the RFXCom and not transmitted to, explaining why panic mode can be detected and not triggered. This is an RFXCom issue and not something in Domoticz.

So I just emailed Rfxcom to ask whether the manual is wrong or the firmware and I'm waiting for their reply. Will update here once I get an answer.

Hello !

Similar problem for me with the RM175RF. Domoticz can detect it (automatic detection) as RM174RF, but trigger the button has no effect to make ring the detector (although RFXcom user guide say Transmitting is possible with RF433XL). Probably RM174RF and RM 175RF had not the same protocole ?
