Poultry climate control

For poultry housing, I’d recommend looking at dedicated poultry environmental controllers with integrated software, rather than ordinary smart-home automation. These systems use sensors to monitor temperature and humidity, automatically control fans and cooling equipment, manage lighting schedules, and alert you when conditions move outside safe limits.

The best option depends on whether you raise broilers, layers, breeders, or backyard poultry, and whether you need to automate one house or an entire farm.

5 poultry automation systems worth comparing

1. Munters ROTEM Trio

(Best all-around option)

Designed for modern poultry farms, with automated climate control, ventilation modes, environmental sensors, and remote management through the TrioAir app. Supports humidity, CO₂, and ammonia-based ventilation strategies.www.munters.com+1

5. Dhumal AC-2000

Computerized control for temperature, humidity, static pressure, lighting, feed, and water, with optional PC communication software.dhumal.com

Best for: Producers looking for configurable control of multiple barn functions.

What the software should automate

Here are the features I would prioritize when comparing systems.

The controller should continue operating essential climate functions locally if connectivity is lost. Poultry ventilation is a critical animal-welfare system, so backup power and independent high-temperature alarms are important.www.bigdutchmanusa.com+1

Which one would I choose?

• For a commercial farm: Start by comparing ROTEM Trio and Big Dutchman ViperTouch.
• For a simpler, smaller installation: Investigate Munters Smart C/D.
• For an existing Chore-Time equipment setup: Get a quote for CATALYST before considering a different ecosystem.
• For a customized installation: Compare Dhumal AC-2000 and confirm local support and compatibility.

These are preliminary recommendations, not a verified price ranking. Most of these systems are configured around the equipment installed in your poultry house, so request an installed quote that includes sensors, wiring, commissioning, and backup protection.

[Find the best options for my farm]

Yes. There are several good approaches, and the best one depends heavily on whether this is a small backyard coop or a commercial poultry house.

Best options

Solution	Best for	Climate	Ventilation	Lighting	Complexity
Home Assistant	Backyard/small coop	✅	✅	✅	Medium
Hermanas	DIY chicken-coop automation	✅	✅	✅	Medium–High
ROTEM	Commercial poultry	✅	✅	✅	High
Big Dutchman ViperTouch / BigFarmNet	Commercial farms	✅	✅	✅	High
Hotraco Fortica MAX	Professional poultry houses	✅	✅	✅	High
DIY Arduino/Raspberry Pi	Hobby/experimental	✅	✅	✅	High

1. Home Assistant — my pick for a backyard coop

Home Assistant is probably the most flexible solution if you're comfortable installing a small computer such as a Raspberry Pi.

You can connect temperature/humidity sensors and automate things such as:

• Exhaust fans based on temperature
• Additional ventilation based on humidity or air quality
• Coop lights on a sunrise/sunset or fixed schedule
• Heaters during cold weather
• Automatic vents/dampers
• Alerts when temperature gets dangerously high or low
• Historical temperature/humidity graphs
• Remote monitoring from your phone

There are also Home Assistant projects specifically designed for ventilation control, including PID temperature control, outdoor-temperature comparison, CO₂-based ventilation and fan assistance.github.com

2. Hermanas — unusually well suited to a chicken coop

If you want something specifically designed around chickens rather than adapting a generic smart-home platform, Hermanas is interesting. It's an open-source Raspberry Pi system that provides temperature/humidity monitoring, automated ventilation, scheduled lighting, sunrise/sunset automation, cameras and a web dashboard.github.com+1

Hermanas on GitHub

This would be my first thing to investigate if you want a DIY "smart chicken coop" rather than a commercial farm controller.

3. Commercial poultry controllers

For a large flock or production operation, purpose-built poultry controllers make more sense.

ROTEM offers controllers that integrate ventilation, lighting, feeding, watering, weighing, environmental sensors, alarms and remote monitoring. Its Trio Air provides cloud-based remote farm management.rotem.com

Big Dutchman has ViperTouch controllers and BigFarmNet software. ViperTouch can manage ventilation, lighting, feeding, watering and other poultry-house functions, while BigFarmNet provides PC-based monitoring/control of barn climate and production data.www.bigdutchmanusa.com

Big Dutchman Controls & Software

Hotraco Fortica MAX is another all-in-one commercial system covering climate, ventilation, lighting, feeding, watering and other poultry-house processes, with an associated farm-management app.www.hotraco-agri.com

What I'd build for a small coop

For, say, 5–50 chickens, I wouldn't buy a commercial poultry controller. I'd use:

Home Assistant + temperature/humidity sensors + smart relays + fans + LED lighting

with rules roughly like:

Temperature
    ↓
Too hot → increase ventilation
Normal → minimum ventilation
Too cold → reduce ventilation / activate safe supplemental heat

Humidity
    ↓
Too humid → increase ventilation

Time / sunrise
    ↓
Lights according to desired laying-day schedule

Safety
    ↓
Extreme temperature → maximum ventilation + phone alert
Controller failure → hardware-level fallback

I'd also strongly recommend hardware fail-safes rather than making the chickens' survival dependent entirely on software or Wi-Fi. USDA poultry guidance notes that environmental controllers can monitor temperature, humidity, ammonia, CO₂ and other conditions, and commercial systems commonly include high/low-temperature and power-failure alarms.www.aphis.usda.gov

For a backyard installation, Home Assistant is the most versatile, while Hermanas is the most directly chicken-coop-specific. For a commercial operation, I'd look at ROTEM, Big Dutchman, or Hotraco.

If you tell me how many chickens you have, the approximate coop dimensions, and whether you already have fans/lights/vents, I can design a specific software + sensor + hardware setup for you.

Several specialized agricultural climate control systems and farm management software platforms handle automated ventilation and lighting using environmental sensors, including ammonia (N H 3 cap N cap H sub 3𝑁𝐻3 ) and temperature. Rather than standalone "software," these are integrated hardware-software climate controllers connected to cloud management platforms.

Major systems capable of this level of automation include:

• Munters Controllers (Platinum Pro / Touch, Rotem Pro/One, and Trio) : Munters offers a dedicated Munters Ammonia Sensor that integrates directly with their Platinum, Rotem, and Trio climate controllers. It delivers real-time N H 3 cap N cap H sub 3𝑁𝐻3 data to trigger a dedicated ventilation override program when ammonia spikes, while simultaneously managing standard temperature curves and multi-zone lighting schedules.[munters.com](https://www.munters.com/en-us/products-cms/controllers-and-automation/ammonia-sensor/)
• Big Dutchman (viper/BigFarm) : Utilizing the Dräger-developed DOL 53 ammonia sensor, Big Dutchman systems continuously monitor real-time gas concentrations. Their house computers and management software link this data directly to the barn's exhaust and ventilation mechanics to optimize air quality and temperature simultaneously.[munters.com](https://www.bigdutchmanusa.com/poultry-production/news/new-sensor-is-a-milestone-for-poultry-production/)
• Stienen Farm Management (PL-9500 / PL-9600 Next Gen) : Stienen’s management computers tie together data tracking for ammonia (N H 3 cap N cap H sub 3𝑁𝐻3 ), carbon dioxide (C O 2 cap C cap O sub 2𝐶𝑂2 ), relative humidity, and temperature. Paired with their FarmConnect software ecosystem, they automate ventilation behavior and climate adjustments based on these combined sensor inputs.[munters.com](https://www.stienen.com/en/poultry-farming/)
• Fancom (MultiLin / Lumina) : Fancom provides stable ammonia sensors that link into their house controllers to manage climate rules, adjusting ventilation capacity dynamically when gas levels pass predefined thresholds to protect animal respiratory health.[munters.com](https://www.fancom.com/news/stable-ammonia-sensor-for-healthier-animals)
• BRNIT Smart Poultry Automation System : An IoT-based automation platform utilizing industrial-grade sensors for gases like ammonia and C O 2 cap C cap O sub 2𝐶𝑂2 , temperature, humidity, and light intensity to automatically command relay boards for ventilation and lighting configurations via web and mobile application panels.[munters.com](https://www.brnit.com/en/products/PF/)
