I see that this is a few years old now, so not sure if work continues on this project. I could see many people paying for a variant of this split into two components that communicate via Zigbee and/or WiFi using the OpenTherm protocol: 1) A "receiver" (server) component that would be installed in a mechanical room, connected to line power (24 to 240VAC), and wired to control one or more HVACR devices. This could be a standalone product that could be controlled by off-the-shelf OpenTherm thermostats. 2) A "sensor" (client) component with temperature sensor, humidity sensor, and a 10-year lithium battery like the ones used for smoke detectors. It would have no display and would be configured wirelessly.
Just bought your adapter for an arduino and got the hooked up to my vitodens 100 and talking back to homeseer automation using the engimatheatre arduino plugin in api mode
Is this suitable for Home-assistant? I need to interface my Riello Boiler with Home-assistant to read some boiler parameters. Better with opentherm gateway integration for Home-assistant.
Thank you, this very useful, I have one Buderus GB012 without any thermostat, and one berreta with their smart open therm thermostat. I will try this with the buderus one, it would be nice to add mqtt support to integrate it with other smart devices.
Здравствуйте Игорь, а магазин Diyless, ваш? А то что то там не отвечают по мейлу. В Армению продаете ОТшилд с БЛЕ датчиком? И не понятно отображает ли там давление и есть ли управление dhw ?
Can it pass error messages through, our system depressured and the first thing I knew was a complaining family so it would be nice to instead get an alert
Kendim kombim için röleli termostat yapacaktım fakat Buderus gb122i modülasyonlu kombi olduğu için on- off verimli olmuyormuş. Sizin termostatınız opentherm uyumlu ama yazılımınız kombi modülasyonuna uyumlu mu? Isı direnç sensörü daha uzak olmalı.
Is it possible to design a fully wireless solution? I assume, with the realization of what we can see in the video, you would have to place the module to the place where you want to control the temperature, however the signal is not transmitted to the OT port of the boiler wireless.
@@IhorMelnyk Thanks. I have a Remeha c-Mix controller that in theory supports opentherm. I measured with multimeter the voltage and it reads and jumps between 5 and 5.4V. Does it have a different range? Thanks again
@@IhorMelnyk I'm thinking about putting it together. How can I transmit between two modules over WiFi? Can your box act as a relay host between the room thermostat module and the boiler? What if I want to control more zones/rooms? Thanks
Your work is very interesting and I was interested in buying your PCB's, but I see that you do not answer the questions that are asked of you, and is a pity

You can implement some notifications on the sketch level

Isı direnç sensörü daha uzak olmalı.
Hi, is it compatible with Daikin Ndj series condense boiler? The boiler supports opentherm.
This work on all centrals ? Mine doesnt suport open therm
It is for OpenTherm boilers only
Is it possible to design a fully wireless solution?
I assume, with the realization of what we can see in the video, you would have to place the module to the place where you want to control the temperature, however the signal is not transmitted to the OT port of the boiler wireless.
Of course it is possible, just use similar controller to transmit commands over Wi-Fi or make wireless temperature sensor.
@@IhorMelnyk Thanks. I have a Remeha c-Mix controller that in theory supports opentherm. I measured with multimeter the voltage and it reads and jumps between 5 and 5.4V. Does it have a different range? Thanks again
@@fulesmackofule Most of the time line is in idle state. Voltage should be under 7V. So I think you have the same range

does the thermostat work on viessmann vitodens 100?
Would be cool to know that if anybody confirmed it...
@@krzysztofmachelski4415 Yes I use it with Vittdens 100
Also working with vitodens 050-w

Hi +Jose Manuel Romero. I am sorry, but I don't have enough time to look through the comments. I see you have managed to find answer to your question.
здравствуйте есть ли СЕЙЧАС возможность отправить термостат в РФ? Готов купить.
в РФ больше не отправляю
Здоровэньки булы! Есть возможность отправить термостат в РФ? Готов купить.
Акцент просто кошмар!
