Hey
I opened an issue on Github.
Hoping you might support the SIR321
Hi just received my Homey yesterday and trying to install Secure RT321 thermostat
When I add the 321 through Secure App I get following instructions:
as the Homey App wonāt work in landscape and you canāt zoom in or out or pan left to right I cannot get the critical info OR see the URL for full instructionsā¦
Sooooo close yet sooooo farā¦
Anyway the text could be wrapped to the screen so you can read it?
Iāll go off and find manuals as they may give insight, it would be extremely useful to be able to read these instructions.
This is from the source code
"instruction": {
"en": "Put thermostat in installer mode(dip switch 1 On), turn the dial to āLā and press the dial. Full instructions: https://forum.athom.com/discussion/comment/42270/#Comment_42270",Thanks
Very helpful, appreciated ā¦
Hopefully the App will be updated to make it a little easier for new users 
When looking at the Device Secure RT321 you have screen Thermostat Mode seeā¦
What is this for ? What does it do ?
Any ideas would be helpful ā¦
Thanks
Mike
Did someone manage to add the SES 002 attached to a SES 303?
Trying to include the Srt323 but after the include process there is no thermostat a short error is visible.
Homey is having latest version.
In domiticz it was working good.
Is there a fix for the problem I have?

Hello every body
Iām new here and alreeady very disapointed.
About the message you cannot read, itās written : https://community.homey.app/discussion/comment/42270/#Comment_42270 but this page doesānt exist.
I can see you have some difficulties when trying to include SECURE SRT 323 or 321 or else.
Iām like you.
I read and erspect the whole procedure but at the end āfailedā and no new thermostat.
I tried with 3 units, and same result.
Is there anybody here who succeded ?
Thanks
I canāt add my SRT 323 at all!? Homey finds it but doesnāt add it!? What am I doing wrong??? I removed it and retried multiple times.

Hi Kamer,
I confirm itās very difficult to add SRT 323 with Homey.
I succeed only one time and only with one SRT 323.
For the others it was impossible.
Later, after resetting my Homey I couldnāt add any SRT ! Noneā¦
That was one more reason to send it back to my customer.
Next box will be Jeedom. I hope it will be better.
Good luck.
So there is no one here who can fix it?
I bet @Priknr1 can fix that for ya but he was last seen in march on the forums soā¦
I am Sorry guys, I donāt see myself making any changes soon.
I am rebuilding a new home, and my wife just gave birth to a healthy girl.
Besides the app is still SDK v1, so not compatible with homey V3. It needs a rewrite, and it is too complicated for me right now. I suggest to lobby around here to find another developer to take this over.
Congratz m8!
Congrats on your new family member, Patrick!
Where then can one find someone willing to take over this project!? I have no knowledge what so ever about these things.
Another thing, how come the Homey generic z-wave canāt find the SRT 323?

Did u read this post Kenneth?
Yes Roco, and I did all those things too, numerous times. Iāve searched the net now for two days and nothing have worked yet. The Homey and SRT323 connects, but it isnāt added!?
