Working great with the supplied sensors. Just using the inbuilt web page right now. My MSZ-AP20VGD took a bit to find the CN105 as it PCB label was hidden, but a photo found it! Plus 'wrenching" the cover off the unit was nerve wracking but it seems to be how it should be done
My MSZ-FH35VE was far easier to dismantle and install
This is the hardware Ive been dreaming of. Had my in ceiling unit connected to Apple Home in less than 20 mins. Online instructions are great, and best of all at a fraction of the cost. Very pleased.
This is a great project that's been badly needed. I'm using this with a Mitsubishi HyperHeat ducted heat pump (SVZ-AP36NL + SUZ-AK36NLHZ) and it works exactly as I had hoped. The Serin Labs parts are quality, the software is slick, and the support is excellent. AFAIK, everything is open source and the creator will readily share information with customers, which is a huge change from the traditional HVAC industry. I'm really glad I took a chance on this, it got me exactly what I needed for a really good price (Home Assistant integration with fan speed control and the ability to send the controller external temperature sensor values from existing HA-paired sensors so it can do inverter ramp for a power curve identical to the Mitsubishi MHK2 controller).
Easy to setup! Great product
Worked real easy. Amazing product.
Product exceeded my expectations, well packaged too.
Clear packaging. Good documentation. I did have some trouble getting it recognized in HomeKit because I first connected it to a "guest" WiFi network, which I suppose didn't allow the controller to connect to the HomeKit bridge. I had to reset it a few times until I could successfully change the network. It has worked without complaint or issue since then. The only feature I wish it had was kWh / energy monitoring. This appears to be a HomeAssistant only feature?
Thanks for sharing! I'll look into adding support for energy monitoring in the HK-compatible firmware. I appreciate you bringing that up.
I just configured 5 of these controllers for my multi zone Mitsubishi system. Flashed each one with the new matter compatible firmware, and then paired each to my Samsung Smarthings hub. I was very impressed how easy it was to flash and set them up . I'm very happy so far by the quality. Would highly recommend to anyone. Only wish there was a option to force the vane on one of my Mitsubishi units to be fixed in a certain position due to how it was installed. Maybe this can be added in a future firmware update.
Works super well and seamlessly
Works great! Had to reflash since I needed ESPHome but worked out fine.
Just worked. Exceptional support. Full recommendation
Great item and excellent seller! Very helpful, responsive, and easy to work with. Outstanding customer service. Highly recommend!
Perfect for a three-zone Mitsubishi setup
Flashed three of these (2× MSZ-WR12NA, 1× MSZ-WR18NA on one multi-zone outdoor unit) with Serin's ESPHome firmware and had all three running as full climate entities in Home Assistant in an afternoon. Solderless Grove cable clicks into CN105, the 20 cm length hides the whole controller inside the housing, and you get full bidirectional control — setpoint, mode, fan, vanes, temp sensors — completely local, no cloud.
Two Linux flashing notes that saved me second-guessing: my user needed to be in the dialout group for the board to show up, and after flashing it wouldn't join Wi-Fi until I unplugged it from the PC and powered it from a battery. Neither is a fault, just worth knowing.
Works great and unlocks so much functionality! Well worth it!
Worked great. It booted up and was already flashed due to the fact that I ordered the remote temp module.
Explicit directions, simple installation, functions exactly as advertised, fast delivery, 6 star rating if I could.
If you are thinking about it, just do it!
Works as described. Firmware was easy to install from the website.
Great unit, install was easy
Totally bought this on a whim and after installing it, I can’t believe how I lived without it. Seriously Mitsubishi, why didn’t it come like this in the first place? Can’t recommend this more. Just buy it. Just install it. Super easy. TEN STARS!!!!!
Compact well made de-cloudifier for home assistant
After flashing the ESPHome firmware onto the chip, I was immediately able to add it to Home Assistant, things have been working perfectly.
While you could probably save a little bit of money and source the parts for this controller yourself (the chip is just a NanoC6), the convenience of having everything shipped together within just a few days rather than waiting multiple weeks for shipping from China easily makes the extra cost worth it.
Additionally, the seller is up front that the device they are selling uses open source firmware and provides links to said firmware on their website along with instructions on how you could build your own version of the controller if you so choose. I'm happy to support a creator that is honest about their sources and willing to share knowledge with the tech community.
Easy to use and works flawlessly.
Absolutely thrilled with these — wish I'd bought them sooner.
I picked up two of these for my Mitsubishi mini splits (bedroom and living room) and couldn't be happier. Installation was genuinely easy — plug into the CN105 port behind the front panel, and that's it. No wiring, no electrician, maybe ten minutes per unit.
While the Apple Home support is there, I run Home Assistant and it integrated perfectly. I've got remote temperature sensors feeding the units so they heat and cool based on where I actually am instead of what the head unit thinks the room temperature is, plus schedules and away-mode automations that shut things down when nobody's home.
The savings have been real. Being able to actually schedule these instead of leaving them running has made a noticeable difference on my bill.
Highly recommend
Quick shipping and board, case, and cable are well-made!
Descriptive instructions and quick setup via their web flasher. Now I can control our Mitsubishi Minisplit fully in HomeAssistant instead of hoping the IR repeater relays the commands correctly. Highly recommend!
Serin Controller for Mitsubishi Mini Split Heat Pumps
Surprisingly easy to install. Now my mini splits are in my apple home app. Love it.
Excellent device, works great with my system. Seller is very responsive and helpful if needed! Thanks!
Hardware is great, lots easier than sourcing all the parts yourself, and I wouldn't have built it as well even if I did. Seller is quick with support too.
