Step 6 of the guide to setting up the RV50 for Ignition requires typing in the IP address of your Ignition gateway, but what do you do if you have redundant gateways?

Hmm, it looks like there’s a couple issues with using one of these in a redundant setup. I think you’d need two of them, one for each gateway, but then the notification profile settings also need to gain an additional “Backup Host Address” setting that gets used when on the backup gateway in a redundant pair. ---

Hi Ben 🙂 Have you figured out how to configure the RV50 for a redundant pair of gateways? I have the same problem. If the backup server is the active gateway I receive the sms notifications in the case of an alarm, but I am not able to acknowledge the alarm since the RV50 is trying to send an ack message only to the configured master address. ---

Ah sorry I wasn’t able to get this working. I actually just went for the Twilio module.I think it needs some updates from IA to get it working as Kevin described above. ---

We are seeing the same issue. Is there any enhancement request in the Ignition Que to address this issue? ---

I am currently waiting for a reply on my support ticket on this issue. ---

Following - there are several redundant applications where I’d like to have redundancy on the RV50 as well either through a single RV50 or two of them. ---

I just made sure there’s an issue for this in our system. Bug your support reps to get it prioritized. Reference IGN-2188. ---

Best workaround is not to use the Sierra SMS units for SMS and use a better unit. ---

Ouch..........Okay, what would you recommend? Note, the only devices listed as compatible with the SMS module are Sierra Wireless devices: [Ignition SMS Notification Module | SMS/Text Alarm Notifications](https://inductiveautomation.com/ignition/modules/sms-notification). ---

Disclaimer: I wrote this how-to: > [@HOW-TO: Use a Teltonika 4G Modem as an SMS Dialler](https://forum.inductiveautomation.com/t/how-to-use-a-teltonika-4g-modem-as-an-sms-dialler/99613): > > There has been some complaints about the SMS capability of the SMS Notifications module that I have seen recently. Most of these centre around how the Sierra Wireless SMS modems have no feedback on whether an SMS has been sent or if the modem is even connected. I personally have a couple of issues with the module: The Sierra dialler uses UDP, so there is no confirmation a packet ever made it to the unit. The dialler cannot have a gateway address configured on it, so it MUST be on the same su… It is not "supported" by IA, but it is more reliable and you can do much more with a bit of scripting to verify things are working every time you send messages etc. ---
