Managing heating in Home Assistant - part2

[@sekt1953]

Thanks for your great inspiration, I want to read the AppDaemon documentation, and your examples, thank you so much for your videos

[@carstenhiort6862]

Many thanks Vaclav, I am currently planning on getting our gas boiler smart. Ours is controlled by one thermostat in a hallway and of course it reaches it's shutoff temperature way before my wife's office reaches an acceptable level. As I can control the boiler by the voltage I send to it, I'll build an ESP32 based HA-Actor that can set it to 0 or 50-100% Power and thanks to your Videos I do now have quite some ideas on how to control the stuff. I'll replace the semi-smart manually programmable thermostats in the important rooms with ones that can tell me their state in HA so they essentially request heating power, instead of the single thermostat in the hallway. I've already placed cheap bluetooth thermometers in every room, collecting their data into HA, as I intended to use these for calculating the demand for heating power, but that seems to overcomplicate things a bit. Yet they are still useful for fine tuning and to figure out if something goes wrong.

Thanks for the detailed insight - it is an useful resource for my own intentions.

Hello Vaclav I have made the same strategy for my central heating system in my house with separated adjustable valves and a switch on/of the boiler. After 2 years it turned out that it makes no sense :(. For now, I keep a high temperature for the boiler because for rooms about temperature care valves and if all of them are close the boiler has a very short circuit for hot water. When manage together valves and the boiler switch system was very unstable. I found the video because I switch from Z-Waves ( Vera light - which is extinct) to ZigBee and other open systems like HA. To be honest, the scheduling in HA is not as easy like in Vera :(. Anyway, very nice video.

Hi Vaclav, I greatly appreciate your education work! I am about to develop my heating based on MAX! Cube system. Can you share also the Node-Red flow as well please? Thank you!

[@doukho]

The node-red flow would be very helpfull indeed!

[@cagcos]

How did you get on with max cube system? I have the same. Would be interested in what you achieved. Thanks

Hi Vaclav! I'd like to control my Vaillant boiler with Home Assistant. The idea is to have a temperature sensor in every room. When temperature falls beyond what's set on a TRV, Home Assistant should turn on the boiler and a water pump that circulates the water in the heating system. I bought a smart switch that will turn on the pump, but I don't know what to use to turn on the boiler. I saw on one video that you use some Arduino switch. Do you have some link where to buy one and how to use it to control the boiler? My boiler is Vaillant like yours.

[@josereis2742]

Hello, it’s a great video! You have 2. Special nodes in node-red. How can I get this nodes? Thank you

[@doukho]

Hello Vaclav, Thank you for all the interesting video's (especially on heating and your dashboard). I decided to try and configure my system like your's since I find it elegantly designed (room per room thermostat with high-low temperature programmable). The only difference in hardware is that my TRV's do have a built in temperature sensor which i use to determine mean room temperature (I tweaked this in some rooms to correct for overshooting or undershooting of the smart TRVs). I do have the following problem: when using eco mode, I cannot make my boiler switch turn on when setting a higher desired temperature for a room. The switch for the boiler only jumps on when I flip the 'somebody_home' boolean off and back on. When I set the high temperature in a room the appdaemon log shows the thermostats target temperature updating, but it doesn't trigger an heating update? I took a look at your appdaemon script: is it possibly a problem with the bookean 'force' which is only set to true in the 'somebody_home-updater' part of the script?

[@bruxy70]

Thanks for letting me know. I though it was working, but haven't been using it throughout the summer. Let me test that, and if it does what you say, I will fix that.

Hi Václav, thank you for sharing, I am working on a similar project with !MAX system valves but struggling with the boiler control. I managed to find the boiler’s jumper, and replaced with a Shelly MQTT Switch. What I am missing now is how to control the boiler if even one valve is needed heat? Can you eventually share your node red code please?

[@bruxy70]

I control that from the AppDaemon script. Shared in the description. I do not use NodeRed for heating.

[@rlajos]

@@bruxy70 Thank you, I will check out your AppDaemon video first! I truly appreciate your work!

[@oddiwahn]

Hi Vaclav, thanks for your great videos which helped me a lot. I really like your system because thats what I was looking for. Like Alexander I am using TRVs with embedded sensor. To get it working, I added the attribute "current_temperature", since my sensors are not entities of type "sensor.XXX" but "climate.XXX" and their default state is the heating mode and not the temperature: 107: self.listen_state(self.temperature_changed, sensor, attribute="current_temperature") 181: sensor_data = self.get_state(room[ATTR_SENSOR], attribute="current_temperature") 285: return float(self.get_state(room[ATTR_SENSOR], attribute="current_temperature")) 334: temperature = float(self.get_state(room[ATTR_SENSOR], attribute="current_temperature")) The main reason why I like your script is the boiler control, i.e the "eco" mode. I found a bug there in the __check_temperature function. You should replace the "elif" with "if" in line 195. Otherwise, if the temperature is below the target the boolean "some_below" will never ever set to true, so eventually the heater will never get switched on... if temperature < target: all_above = False elif temperature < (target - HYSTERESIS): some_below = True

[@bruxy70]

Thank you!

[@ianmcneilly2906]

Great video , this is what I need to get into as I have almost the same system. One quick question what node do I use to read an analog value (temperature) to be able to make calculations in node-red.It seems everybody (and the documentation)is only interested in event initiated type programms (light,fan or heater switching).

[@brientmickael6649]

Hi mister This is really really interesting!!! awesome!! It is complicated for me. I have a central heat pump , Atlantic. I am renting a house, I cannot touch the thermostat on the radiators. i use Cozytouch cloud with a bridge. i integrated Cozytouch a home assistant. I would just like to do automations with that according to the people present, the weather outside. would you be willing to help me? Thank you for your reply

[@arhitektche]

Tryng to do the exact same thing here. My question is : when you turn off the boiler from the thermostat contact, what happens to the hot water? The gas boiler also makes the hot water for shower ob demand, how does it know to turn on when you turn the tap on

[@bruxy70]

Water is fine, It is the same thing as when I turn heating off in the summer - it still heats the water.

[@arhitektche]

Great! I am going to use shelly trv's ... just need to turn off the heating when all valves close

[@MichaTadeuszJanas]

Hi Vaclav, thanks for the great video. I have a question for you, can your automation be used without any TRV, but only thermometers in each room? Sorry if my question seems silly, but I'm just getting started in HA and my current logic is based on node-red.

[@jamalnasereddin1379]

Hi Vaclav, thank you for sharing your great work and wish you a happy new year. I am new on using home assistant, previously I was using Alexa, Google Home and another 3rd party services to manage my home automation, and now I move to the home assistant, can you please share with us the Node-Red configuration to import it to my system and after that I will configure it to work with my home system.

[@bruxy70]

Jamal, I do not use NodeRed anymore. The general HA automations got much better recently, so I do it there. While the core of the logic is in the AppDaemon that I already shared. So the only thing I do in automations is turning the day/night switches for each room, based on who is home.

@@bruxy70 Can't use all! I have a couple of outside lights which I want to turn off after midnight. The problem is that some are switch. So I need to have a list of items and process them one by one. Thank you very much

[@bruxy70]

@@iulianch Then use the list. When you call the service, entity_id can contain a list of entities. Or, you can create a group and then turn the group off - www.home-assistant.io/integrations/light.group/ Also, you can create a light from a switch - I actually use that as well: www.home-assistant.io/integrations/light.switch/ I mean, you could create a loop by parsing an array in NodeRed, but there is no point in doing that as you can feed the service with a list and call the service once. And I do not use NodeRed anymore btw. The native HA automation got so powerful recently, so that I converted to using that and removed NodeRed completely. I felt that having 3 different automation platforms was a bit too excessive.

Hello Vaclav, I have noticed that you are also using automation for MikroTik, do you care to share (maybe in a movie) what do you use it for. Is it worth it and how does this work. Do you use it to get information on who is at home, based on accessible devices?

[@bruxy70]

James, I do not use NodeRed anymore. I moved back to the regular HA automation, as it became quite powerful a few months back and it does all I need. But what it basically does is, it sets the night/day toggles (helpers) for each room based on the selected mode and who is and is not home.

To už jsem řešil před dlouhou dobou, mám tam termistor, který je ponořený do vody uvnitř skimmeru, a v prostoru čerpadla mám pak Wemos D1 mini, který ho čte - s ESP Home. Ale dnes bych to řešil spíš digitálním teploměrem, něco jako arduino-shop.cz/arduino/848-eses-vodeodolny-teplomer-pro-jednodeskove-pocitace.html. Nemusel bych pak složitě teplotu vypočítávat z analogové hodnoty.
