Today, I attempted to use the Click PLC for email notifications, but unfortunately, I encountered connectivity issues within my network. I require a solution for sending mass alerts when a specific temperature threshold is reached. Are there any alternatives that do not rely on batteries and instead operate at 24vdc with WiFi capabilities?
When setting up email alerts, I rely on a Red Lion HMI or Data Station paired with a VPN Router and an AuthSMTP account. While this may come with a higher hardware cost compared to other options, the time saved in getting it to work consistently is substantial. However, if you only require a single email alert for a specific condition, this setup may be more than what you need.
I have configured a system to send out text notifications when alarm thresholds are exceeded, which works effectively despite poor mobile signal in the area. I am unsure of the limit on the number of phone numbers it can store, but it allows for customized texts with delayed intervals and the ability to adjust parameters via text message. Additionally, it includes an event log feature if necessary. Our current system has four relay inputs that meet our requirements. In addition, I have set up a PLC-driven webpage accessible through the company VPN for remote monitoring, particularly for a master alarm monitoring 40 different temperatures.
The Teltonika 4G routers I utilize offer diverse capabilities. They feature a digital input for sending emails and SMS alerts, as well as the ability to function as a Modbus TCP Master to execute tasks based on Modbus TCP data. A helpful example can be seen on the Teltonika Networks Wiki, showcasing a router responding to a digital input from a UPS, triggering SMS and Email alerts. The RUTX09 model I commonly deploy typically costs around $300. Teltonika Networks, a reputable global manufacturer of IoT connectivity devices with extensive market expertise of over 25 years, offers top-notch products for IoT solutions. While the RUTX09 lacks Wi-Fi functionality, it boasts a WAN Ethernet port with mobile signal failover capability.
Puddle mentioned that they have set up a system to send out text alerts when alarm levels are triggered, despite weak mobile signals in the area. The system allows for custom text messages, delay intervals, and parameter adjustments via text. It also features an event log and four relay inputs. Additionally, a PLC-based web page was created for remote access through the company VPN, specifically for monitoring a master alarm for 40 different temperatures. However, there have been difficulties in getting the system to function properly.

I'd recommend looking into the ESP32. It's a low-cost microcontroller with integrated Wi-Fi and it can be easily powered by a 24vdc. You can easily program it to monitor temperature changes and send email alerts. Plus, there's a strong online community available if you need any guidance on setup or trouble-shooting. Also, consider redundancy in your alert system for reliability, perhaps having an SMS alert alongside your email notifications.
Based on your requirements, I would suggest checking out the Siemens S7-1200 PLC series, which supports email notification and operates on 24vdc. It also has an optional WiFi module if you need wireless connectivity. You could easily program it using their TIA Portal software to send alerts once a specific temperature threshold is reached. Make sure you have a stable network connection for best results. Plus, Siemens provides pretty good support if you encounter any issues during setup.
Have you considered using a WiFi-enabled relay module or a smart thermostat that runs on 24V DC? These devices can be integrated with your existing setup and programmed to send alerts when the temperature exceeds your threshold. Some models even have built-in email notification capabilities, which would eliminate the need for the Click PLC while still providing you with reliable alerts. Plus, they can be powered directly from your 24V system, keeping everything straightforward without the hassle of battery replacements.
Have you considered using a WiFi-enabled temperature sensor like the Sonoff TH16 or the ESP8266-based devices? These can run on 24VDC with the right power supply and can send alerts directly via email or even integrate with services like IFTTT or MQTT for broader notifications. Plus, they don’t require batteries, so you won't have to worry about that issue! Just make sure your network is stable for the best performance.
If you're looking for a reliable solution to send mass alerts without relying on batteries, you might want to consider using a WiFi-enabled temperature sensor that can work directly with your 24VDC system. Devices like the Sonoff TH16 or other similar smart relay modules can handle temperature monitoring and have built-in connectivity features to send alerts via email or even through apps. They can usually be powered directly from your existing setup, alleviating those pesky connectivity issues you experienced with the Click PLC. Just ensure that the sensor you choose is compatible with your existing network and can handle the temperature range you're monitoring.
