Integration of Tuya devices with Satel and Ropam alarm systems: one-way communication

Szyszkownik Kilkujadek 7788 19
Best answers

How can Tuya devices be integrated with Satel or Ropam alarm systems to send alarm sensor and armed/disarmed status one way to IoT devices?

Yes, but not directly: you need an intermediary such as Home Assistant or a relay-based bridge, because Satel/Ropam do not talk to Tuya natively [#19824535][#19825000] Satel can expose status through ETHM1 Plus integration, and Ropam can do it via Modbus on the NeoGsm-IP 64, after which HA can drive Tuya devices using localTuya, Zigbee, or even the cloud, though cloud dependence is less reliable [#19824535][#19825000] For a simple one-way solution, you can connect a Satel output to a Tuya relay/switch module input and then create Tuya app scenes that react to the switch state change (NO/NC) to lower blinds, turn off lights, etc. [#20033764][#20445451] Another proposed variant is to use one Tuya module to read Satel outputs on S1–S4 and a second Tuya module to control relays based on those state changes, but delay between devices remains a drawback [#21532207] If you want to send control into Tuya directly, localTuya requires knowing the DPS number [#20030359]

    Has anyone done any integration of equipment running Tuya with a Satel or Ropam alarm system?
    The communication could even be one-way, so that the alarm exhibits violations of individual motion detectors and whether it is on standby.

    Theoretically possible - Tuya+Home Assistant + Satel Integra + ETHM1 plus or Tuya+Home Assistant + Ropam NeoGsm-IP 64 via modbus.
    Just what for, Tuya detectors have a lot of errors (which are less important in the case of automation control), delays, etc - I wouldn't use them as an alarm element - they could cause false alarms. By default Tuya works in the cloud, so the Chinese can disable the alarm :) . There was a big outage with Sonoff recently, Xiaomi's cloud before that, and Tuye will probably come along too, especially as they are working on new developments and are rather far off the mark (at least in terms of HA integration).
    A lot of potential problems - it's better to give good alarm detectors (and suitable for the workplace), and do automation on Ropam or Integra. To this you can add e.g. Home Assistant (or HA-based AI-Speaker) and e.g. reading the status of the detectors from Integra, and the devices on zigbee and you have a system without dependence on external services.

    @sk1977 thanks very much for your reply but it seems you didn't quite understand what I was asking.
    The idea is to send the status of the alarm sensors to IoT devices. This could be via Zigbee.

    Basing the alarm on Tuya sensors is not acceptable.

    I don't want to do automation on the alarm because it doesn't work. To change something in Satel you need to know Dloadx well. To change something in Ropam automation you need to know how to program.
    This is not the way to go. That's why you have Tuya, for example, so that the average person can get to grips with automation.

    - actually the same way - you won't do it directly - Satel can "output" the data via ETHM1 plus (integration) and Ropam via modbus (only version 64 if I remember correctly). Possibly using the outputs and connecting to Tuya supported devices, but these are further problems to solve. So you need an intermediary device - which will receive data from the control panel and can control the devices (e.g. HA). The transfer of data to the Tuya cloud itself is also a difficult topic - a closed ecosystem, although depending on what is to be controlled and how it is to be controlled maybe it would be possible to bypass this.
    For this type of connection, I would recommend Home Asssistant - you can base your automation on it and connect devices to it (e.g. zigbee multiband or Tuya local, or via the cloud - here the situation has recently become more complicated). In addition, you get rid of the dependence on a Chinese manufacturer and the failure of its servers, or even delays.
    Or use Tuya detectors - the deployment proper from the point of view of the alarm system and automation can be quite different in which case separate detectors would make sense.

    And isn't there such a thing as an input module running in Tuya?
    Server failures I'm not worried about as I have local control with buttons and remotes.

    I know. but they are by definition just controlled by the cloud, unless you have other control - e.g. HA + localTuya or zigbbe.

    That's right :) . I hadn't read about you having button and remote control, I was thinking of some other control. If that's the case, there's no need to keep going round in circles - theoretically doable, but difficult and expensive - the problem is a matter of inputting data into the Tuya ecosystem - you could use some switches connected to the control panel outputs (not likely to be direct) or flood/open sensors and read their status in the app. It's probably simpler and cheaper to use Tuya motion sensors and not connect to the alarm.

    I was thinking of just transmitting the signal from SATEL to the TUYA sensor, something along the lines of "on" and "off". There are so many switches, and two, how to connect it to the control unit.

    Description of operation: I leave the house with the alarm switched on, it sends a signal to the TUYA switch - its status changes, and the TUYA automation system continues to do its job, activates the cameras from private mode to recording, the sensor opening the door to the balcony or window sends notification if something happens, etc. Conversely, if the alarm is not switched on, opening the balcony or window will not send notification

    in a nutshell, the alarm should be an on/off alarm and nothing more... a seemingly simple solution can also be combined with multi-channel switches, but for the beginning I would like so :) someone can help

    To transmit something to Tuya you need to have localtuy and know the dps number.
    I've just recently been figuring out EAMPDW-TY-63 and I'm able to control that from node-red.

    @xury and then can reactions to be configured from the Tuya app?
    Simple actions like: turn off all lights 30 seconds after the alarm is armed. If so, is it possible to configure such a scene and deactivate it when needed?

    I don't know. I have a terrible aversion to all clouds. So I use nothing but google and smartnor.
    From tuya, I only have the aforementioned EAMPDW-TY-63, and only because I couldn't find anything about whether it's possible to upload some alternative software to it. Basically I found nothing, so I decided to figure it out myself and I even succeeded.
    I also had some LED bulbs, but what I did first was change the soft in them to Tasmota.

    Neogsm-ip-64 can be integrated into Home Asistant via MQTT. Tuya equipment also. The HA then acts as an intermediary.

    There is another way that is universal regardless of which alarm you have. Well, you have to connect a Tuya stair light controller via a relay to the outputs of the control panel. We put what we are interested in on the alarm outputs and set the reaction to the change of state in the Tuya application.

    An old topic, but I am currently facing a similar dilemma. I have a Satel Integra 256 PLUS alarm and I was originally planning to do my home automation using the Integra, but the complication of the system, cables etc. is making me go in the direction of Tuya (I'm putting in the right sockets, switches and that's it, no pulling extra cables). The only thing I can think of that the combination of alarm and Tuya would be useful for is the automatic closing of roller blinds and turning off the lights when the Satel alarm is activated. I was thinking of the following solution:

    Purchase the following relay:
    https://pl.aliexpress.com/item/1005003831864732.html?pdp_npi=2@dis!PLN!44,95 zł!27,09 zł!!!!!@0b0a2e9c16766263847805468e455a!12000032247950658!btf&_t=pvid:4b4878e8-ef90-4d6d-9ddf-6ab8ead2c3ef&afTraceInfo=1005003831864732__pc__pcBridgePPC__xxxxxx__1676626385&spm=a2g0o.ppclist.product.mainProduct&gatewayAdapt=glo2pol

    connect the OUT from the control panel to this relay, set the relay as NO, when voltage is applied to the Input, the status would change to NC
    set in Tuya to automatically lower the blinds and turn off the lights if the status of the switch changes to NC, automatically raise the blinds when the status changes to NO.

    I stress that I have never been in contact with Tuya, does this have the right to work?

    .
    Can you write this more clearly? What controls what and what controls the actuators?

    It will work. You set it up in Tuya.

    Just consider whether you are going into WiFi or ZigBee devices. This is an important decision.

    Many thanks for the information! Which do you think is better? WiFi or ZigBee?

    For the time being all I have is a Satel Integra alarm, as I mentioned earlier - I was going to do all the automation on that, but the amount of extra cables to lay out scares me. From what I've seen the Tuya system runs mainly on WiFi, so all the clutter goes away. Sorry for the silly questions, however, I have not been exposed to any system of this type before.

    I know I'm digging up a topic but I accidentally stumbled across it while looking for a solution to the same problem. I just now came up with an idea that may be useful to someone in the future.

    A solution to this problem could be to drive the Satel outputs of a device such as a 4ch Tuya wifi switch (let's call it TuyaA), which we connect to S1, S2, S3, S4. From this point on in the Tuya application, we see that the state of S1-S4 of the TuyaA device changes depending on what Satel sends to this module.

    Now, in the place where we need to drive something from Tuya, we give another such module e.g. a 4ch Tuya wifi switch (let's call it TuyaB in working terms). We connect to its relay outputs for the individual channels, and in the Tuya application we create logic in the style:

    If TuyaA gets a signal on S1 then TuyaB switches on relay 1
    If TuyaA loses the signal on S3 then TuyaB turns relay 3 off.
    And so similarly for any number of outputs.

    This should be fairly intuitive for a reasonably savvy user.
    The only remaining problem is the delay between devices.

Topic summary

✨ Integration of Tuya devices with Satel and Ropam alarm systems for one-way communication is theoretically feasible but involves complexity and limitations. Satel Integra systems can output data via ETHM1 plus modules, while Ropam NeoGsm-IP 64 supports Modbus communication, enabling connection to intermediary platforms like Home Assistant (HA). HA can bridge alarm system outputs to Tuya devices, supporting local control and reducing dependence on cloud services, which are prone to outages and delays. Direct integration into the Tuya ecosystem is challenging due to its closed cloud-based architecture, but local control options exist using Tuya local protocols or Zigbee. A practical approach involves using relay modules connected to alarm outputs to trigger Tuya switches or relays, allowing simple on/off signaling from the alarm to Tuya automation scenes. This setup enables actions such as turning off lights or activating cameras based on alarm status without complex programming of the alarm system itself. Users recommend choosing between WiFi and Zigbee Tuya devices based on installation preferences. Examples include using 4-channel Tuya WiFi switches to mirror alarm outputs and create logic within the Tuya app for automation. Some users employ Node-RED and localtuy integration for advanced control of specific Tuya modules like the EAMPDW-TY-63. Overall, the integration requires intermediary devices and careful consideration of communication protocols, with Home Assistant frequently suggested as a versatile hub.

FAQ

TL;DR: Use a 4‑channel Tuya switch to mirror alarm outputs; "The only remaining problem is the delay between devices." Bridge to Tuya scenes or a hub for one‑way status. For Satel Integra and Ropam users wanting no‑code automations. [Elektroda, Helec, post #21532207]

Why it matters: You can reuse alarm-grade sensors to drive smart‑home actions without rewiring or custom coding.

Quick Facts

How do I send Satel or Ropam alarm status one‑way into Tuya?

Use an intermediary hub. With Satel Integra, export events via ETHM1 Plus integration. With Ropam NeoGSM‑IP 64, use Modbus. Feed these into Home Assistant, then drive Tuya devices locally or via the cloud. Direct input to Tuya from the panel is not typical. [Elektroda, sk1977, post #19824535]

Is there a Tuya input‑only module for alarm outputs?

The thread reports no commonly available input‑only Tuya module. Instead, monitor a relay or use Tuya devices that expose S1–S4 status inputs and trigger scenes from those states. [Elektroda, sk1977, post #19825145]

What’s the simplest wiring method to mirror alarm outputs inside Tuya?

Use two Tuya 4‑channel switches. Wire Satel outputs to S1–S4 of TuyaA to read states. Create Tuya automations so TuyaB toggles relays when TuyaA inputs change. This mirrors panel states to actions, with some cross‑device delay. [Elektroda, Helec, post #21532207]

Can Tuya scenes react when a device state is changed by a relay or hub?

Yes. Create Tuya scenes that trigger on a switch’s status change (e.g., NO→NC). Example: lower blinds and turn lights off when the alarm output drives the Tuya input to NC. "It will work. You set it up in Tuya." [Elektroda, Szyszkownik Kilkujadek, post #20445451]

How do I link NeoGSM‑IP 64 with Home Assistant and then to Tuya?

Integrate NeoGSM‑IP 64 with Home Assistant over MQTT. Add Tuya gear to HA via MQTT, localTuya, or the Tuya integration. Build automations in HA that forward alarm status to Tuya‑controlled actions. HA acts as the universal intermediary. [Elektroda, Szyszkownik Kilkujadek, post #20033764]

Does this need the Internet, or can it stay local?

Tuya defaults to cloud control. Keep it local by using Home Assistant with localTuya or a Zigbee network. That removes cloud delays and safeguards automations when the Internet is down. [Elektroda, sk1977, post #19825594]

Which is better for status triggers: Wi‑Fi or Zigbee in Tuya?

Zigbee suits low‑data, control‑type traffic and forms a self‑healing mesh. It supports up to 250 kb/s and low‑power devices, which helps keep triggers responsive and reliable within the home. Favor Zigbee for sensor‑driven scenes. ["Zigbee Technology Overview"]

Can I use Tuya motion sensors as alarm triggers?

Avoid that for security. "Tuya detectors have a lot of errors," plus delays that can cause false alarms. Keep certified alarm detectors on the panel, and only export their status to the smart home layer. [Elektroda, sk1977, post #19824535]

What can go wrong with cloud‑based alarm→Tuya triggers?

Vendor clouds fail, causing missed or delayed automations. As one expert warns: "By default Tuya works in the cloud, so the Chinese can disable the alarm." Keep critical logic local to avoid outages. [Elektroda, sk1977, post #19824535]

How do I create a 30‑second “all lights off” after arming?

Wire an alarm output to a Tuya input or relay. In Tuya, build a scene: when input changes to “armed” state, wait 30 seconds, then turn off all lights. Optionally add a reverse scene for disarm. You can enable or disable these scenes as needed. [Elektroda, Szyszkownik Kilkujadek, post #20445451]

Can I drive Tuya from Node‑RED using alarm events?

Yes. Control Tuya devices locally by addressing their DPS with localTuya and orchestrate flows in Node‑RED. Users report successful control of Tuya hardware this way. This keeps logic on your LAN. [Elektroda, xury, post #20030359]

Is direct Zigbee output from Satel possible without a hub?

No. You need an intermediary that reads the panel and then controls devices. Satel can output via ETHM1 Plus, and Ropam via Modbus; a hub like Home Assistant bridges to Tuya. [Elektroda, sk1977, post #19825000]
