Boiler heating status in Home Assistant thermostat #620

Closed realthk closed 3 years ago

realthk commented 3 years ago

I've just replaced a simple on-off thermostat (that was also integrated into HA through MQTT) with a Bosch CW400 connected to my Bosch 2300 boiler.

It works fine with EMS-ESP, apart from a small issue: there is no heating status info in the HA MQTT thermostat where it used to be.

The first part on this diagram was with the old thermostat, that provided this info. The green columns on the left show when the boiler was heating - but not any more with the new bus thermostat on the right: screenshot-192 168 8 123_8123-2020 11 18-17_40_47 It was done with status="heating", status="idle" MQTT messages (though obviously it wasn't 100% correct all the time, because DHW has priority over heating, and the dumb old thermostat had no info about hot water production. Now, communicating with the boiler, even that could be avoided)

I guess it is not so straightforward now, as I cannot even see any sensor in HA (or a value in the console of EMS-ESP) that reflects the heating status of the boiler... The only way I could detect it is sensor.boiler_gas==on && sensor.boiler_warm_water_charging==off, then it must be heating right now.

Could the MQTT thermostat messages be extended with this info, or is it too much boiler/thermostat dependant?

proddy commented 3 years ago

simple to add, would need to first test on other systems. What would the name this control? @MichaelDvP what's your opinion?

MichaelDvP commented 3 years ago

This is what heating_active do, Published as single value (always on change) and in boiler_data (scheduled). The boiler value is also registered as ha-sensor.

Not in the case of my Bosch 2300 boiler (recognised by EMS-ESP as Logamax Plus GB122), no.

It is now currently in idle mode, but heating_active is on regardless:

This is when it was in DHW mode (gas was off when copied the values, but probably because water was already hot enough). Warm water charging: on is fine:

  Total heat operating time: 18 days 14 hours 21 minutes

And this is when the boiler was in heating mode for real. The only way I could assign this state to a HA binary_sensor was with a template{{ is_state('sensor.boiler_gas', 'on') and is_state('sensor.boiler_warm_water_charging', 'off') }}

MichaelDvP commented 3 years ago

What ems-esp-version do you use? Can you give me a read 8 18 from a mismatch state? heating active is read from the boiler as a state that burner is on and heating is active. (depending on system it's possible that heating and warm water is heated simultanious).

realthk commented 3 years ago

EMS/ESP is the latest main, v2.1.0

The boiler currently doesn't do anything, but heating active is still on:

Ok, your boiler doesn't have the 0x18 telegram, thats why servicecode and heating_active not working. Can you check with read 8 E4 for the newer version of UBAMonitor. There should be the servicecode and the boiler state, but in this telegram only a few values are known. Maybe we can work out some more.

MichaelDvP commented 3 years ago

Thanks, it should be interesting to have also the complete telegram in DHW mode. But so far i see: ServiceCode in pos 1,2 is always -- ServiceCodeNumber in pos 4/5 is 203 idle, 200 heating flowtemp in pos 7/8 is the same as in pos 23 (which is publishes in DHW mode), maybe it's boiler temp or storage temp ~50°C? Statusbits pos 11 are 00 idle, 03 in heating, bit 0 is burner and i think bit 1 is heating pump I think pos 22 is boilerstate, in heating mode it goes to 09, and 08. If this goes to 0A in DHW mode we have it. The other known positions seem to be ok, Unknown: pos 12 is always 02, pos 21 is always 14, look like configuration bits. pos 13/14: looks like a temperature. ~ 35°C, Is this the flowtemp? do you have floorheating?

@realthk: Can you please try to catch the DWH telegram and look at your boiler to check what temperatures are around 50°, which around 35° . In the show values i think not all is right.

And i wonder from where you get

Warm water current temperature (intern): 31.7 °C

this is only in telegram 0x18.

realthk commented 3 years ago

That's great! I think the main point is to be able to tell what is the boiler doing, so those 203 and 200 values might help.

I have very simple system: no room for water-storage in the small bathroom, so it is a flow-through DHW, and the heating is done with radiators, no floorheating. Water temp is usually around 50C, but when I captured that data, it was just started for test, so it might have very well been about 35C, you're right! I also have Dallas sensors on the pipes, and checking their log now, it seems the outgoing line was 35C indeed.

Do you mean watch raw command? I've issued that command right after starting hot water:

At the beginning, it must have been around thirty-something, at the end, it should have reached the selected hot water temp which is 52. That strange "intern" temp also has reached 52, so it must be correct, wherever it measures:

Boiler: Bosch Logamax Plus GB122 (DeviceID:0x08 ProductID:234, Version:05.03)

  Total UBA working time: 386 days 23 hours 30 minutes

After a long cool-down, 20 mins later, "intern" temp decreased nicely, so it must be correct, while "current flow" is still high, I don't know what it could be:

  Warm water current temperature (intern): 43.0 °C
  Warm water current temperature (extern): 0.0 °C
  Current flow temperature: 54.0 °C

"Current flow temp" seems to be in line with the value displayed on the boiler itself: even though DHW is set to 52C, after having a shower, at the end the boiler was displaying 61C - and that is what "Current flow temperature" shows still, long after it was reached.

MichaelDvP commented 3 years ago

Do you mean watch raw command? I've issued that command right after starting hot water:

I've meant only a read to the E4, but this watch is better. It's always a good idea to start the watch before changing something to get the change, now we don't see tha start of hot water.

So far:

service code number goes to 201 for DHW, thats right.
E4 pos 11 is 5, here we can extract the boilerState for heating_active (03) and _tapwater_active (05) and idle (00)

But there is a lot of unknown stuff in that telegrams

E4 pos 13: looks like another temperature, 48.5° at the end of hot water heating
E5 publishes unknown temperature on pos 4 and 6, pos 4 starting from 29.9° and at the end 34.1° changing often, but not much.

I'll add service code and heating_active. Can you also do a read 8 E5 to see the complete E5 telegram. Try a few times to get it complete or set watch on E5 before the read. (There is an issue in read response if the telegram is send often. I'll change the read response to check destination.)

realthk commented 3 years ago

OK, so I've issued watch on E5, then read 8 E5 Started in idle mode (though the pump was running, because it's on weather compensated mode now, when the pump always runs, but the gas heating was not) then opened the hot water tap.

(connection was lost at this point. The water was still just lukewarm)

I've noticed another slight issue with this boiler/thermostat combo: show values command displays the target flow temperature selected by the thermostat:

Thermostat: RC300/RC310/Moduline 3000/1010H/CW400/Sense II (DeviceID:0x10, ProductID:158, Version:18.05)
  Time: 08:48:24 21/11/2020
  Damped outdoor temperature: 1.0 °C
  Building: medium
  Warm water mode: own_prog
  Heating circuit 1:
    Setpoint room temperature: 19.5 °C
    Current room temperature: 21.2 °C
    Comfort temperature: 20.5 °C
    Eco temperature: 18.0 °C
    Manual temperature: 19.5 °C
    Target flow temperature: 36 °C
    Mode: manual
    Mode type: comfort

which could be useful to see why the heating water has a certain temp, but this is not published as an mqtt thermostat sensor.

There is a sensor.boiler_selected_flow_temperature but when the boiler is in DHW mode, that changes its value to the domestic hot water of course, while a sensor.thermostat_target_flow_temperature would belong to the heating only.

MichaelDvP commented 3 years ago

The e5 is iteresting, but i can only identfy one value: N31-N51: a temperature rises from 28.1 to 71.6°C and than drops suddenly in N55-57 to 33.1°C. This is the exhaust temperature

N9-N27: within 4min something goes from 7-100% (valve/pump/fan?) Can someone with more experience with DHW-flow-systems identify it?

I push a update to dev-build, also include the HA for target flow temperature.

realthk commented 3 years ago

Thanks, great progress: much more detailed info in show values, and also HA sensors! sensor.thermostat_hc1_target_flow_temperature works, and it's useful

At the end of this batch the heating water has finally reached 43.8C while the required temp was 37C, so the gas burner was switched off (seems it does it when temp is > required water temp +5.5C)

But service code number seems to give a clue, isn't it? It is 200 in heating mode, 201 in DHW and 204 in idle. Edit: well, not always: now it's 203 in idle. Though I switched from weather compensated mode to plain room-temperature controlled mode, wonder if it's the reason.

MichaelDvP commented 3 years ago

There are a lot of codes for service number, 203 is idle, 204 is idle and temperature above setpoint. Also in normal action there is 283-burner starting, 284-gas-valves opening, 305 delay after dhw-priority. Other codes are error messages. For checking heating and tap-water it's better to use the (hopefully now working) special publishes.

glitter-ball commented 3 years ago

The boiler currently doesn't do anything, but heating active is still on:

Is this still part of the issue? The blue LED on my boiler will light if heating is active. But, the energy saving pump program may shut the pump off (it runs for about 4 minutes in every 10 when the burner is off...) and the burner. So the boiler appears active for heating, but is actually doing nothing. Is this what you're seeing?

realthk commented 3 years ago

What I'd like to see is when gas is being burnt for heating, then mark the state of the boiler/thermostat as "heating". If it's only the pump running (or gas is on but for DHW, not heating), then no.

Now the pump (or rather the whole boiler controlled by a system thermostat) can behave in two very different modes:

controlled by the room temperature only. In this mode the gas is shut down when the room is warm enough, and the pump works for a few extra minutes only, then it also stops.
weather compensated mode. This is a bit weird, as the thermostat instructs the boiler to keep a constant flow: so in this mode, the pump never stops... The requited water temp depends on the outside temperature, but often so low (around 30C or even less) that a boiler with radiators soon overshoots it even at its lowest power setting, so the gas is switched off, and only the water is circulated until it cools down (more than 5C below the required temp) then the gas is switched back again - and so on... This might work well with floor heating, but not so much with radiators, so I finally switched back to normal mode, controlled by room temp only.

glitter-ball commented 3 years ago

If you're using HA, then you could define a new sensor which defines heating as (burner=on) AND (diverter=CH) rather than HW, or whatever your boiler uses to switch between heating and hot water. Then you'd definitely get what you're after, if it's not available in the MQTT info from EMS-ESP.

Your pump stuff makes sense. I'm using weather compensation with room compensation, so probably the first option. With the second one, the pump may run constantly because the system has no way of knowing what the room temperature is and therefore has to circulate water constantly.

You can change the hysteresis settings to stop the boiler cycling too much at low loads. Mine is set to 10ºC / 10 minutes so the flow temp has to drop 10ºC and the boiler wait 10 minutes between cycles. When the boiler's firing, it cuts out when the flow temp exceeds the setpoint by 4ºC. In mild weather, the boiler does short cycles like the one it's just done on the right here... There's no avoiding it - the burner just can't turn down any lower - and that's with room compensation on. Good advert for not buying a boiler that is too big! But the hot water tank heats quickly *8).

glitter-ball commented 3 years ago

Service Code 200 (CH active) on my boiler also mirrors heating pretty well.

realthk commented 3 years ago

Ah, your pump has variable speed, that's nice. My house is quite small (<75 m2, and from this year with improved insulation) so the minimum 3 kW power of the Bosch 2300 boiler is indeed way too high for maintaining the low temperatures the weather compensated control of the Bosch CW400 thermostat instructs. The boiler switched the gas on-off even during the night many times with steep rise of water temp even at the lowest power: eloremeno (the small spikes are from DHW mode, that also affects a bit my sensor placed on the outgoing heating pipe)

To make things worse, this small Bosch boiler cannot modulate its pump, so that runs always at the speed manually set on it - and this CW400 thermostat won't switch off the pump even though its weather compensated mode is always influenced by the room temperature. Perhaps your thermostat or boiler is more advanced, but no such hysteresis/wait timer setting on mine. It keeps on working if the thermostat instructs it to do so. Which is all day in WC mode.

You are right, for DHW one has to have at least a 24 kW boiler if there is no hot water storage.

So it seems I have to avoid this kind of weather compensated control and stick to a room-based only mode.

Yes, thanks, I'll create HA status based on service code (I used {{ is_state('sensor.boiler_gas', 'on') and is_state('sensor.boiler_warm_water_charging', 'off') }} but that wasn't fool proof, sometimes the gas is on after water charging for a short time)

glitter-ball commented 3 years ago

That's a pain. We are using the same thermostat (it's called Sense II in the UK) and all the boiler settings are hiding in the Commissioning menu of the CW400 with only one exception for me (hot water eco/preheat). Maybe you can find some of the settings in there or maybe, they're just not there on your boiler *8(. My boiler's minimum output is 30% (7.2kW) so control is difficult in mild weather.

Also, I had to experiment a bit with mine to make it switch off completely overnight (unless it gets very cold). There are setback and summer settings that were very confusing and Worcester-Bosch in the UK couldn't explain them all! Anyway, it does go to sleep completely at night now.

I use weather compensation with room compensation, what the manual describes as "Weather-compensated with the influence of the room temperature: Automated control of the flow temperature based on the outside temperature and room emperature. Installation of the controller in the reference room is required."

Sometimes in combi boilers ('flow' boilers?) the burner runs for a short period after the tap is turned off to reheat the plate heat exchanger so that hot water flows immediately when the tap is next turned on. UK boilers have an ECO setting to disable this. That might be why your burner runs after hot water for a short period.

realthk commented 3 years ago

Wow, you're absolutely right, thanks! I've just changed the so called "setback type" to "room temp threshold" (from the default "reduced mode") on the CW400, and the pump is finally switched off after its 3 mins run-on time in night mode! With a setback temp the room won't go below during the night, the pump (and the boiler of course) will remain off until morning, splendid!

Yes, the manual is very confusing indeed, with hardly any real-world examples... Bosch Hungary told me they have no direct end-user support, just gave phone number of local service person, who also turned out to be unhelpful (even rude a bit)

The boiler running all night was a show-stopper for me, I was thinking about sending back this thermostat and get a simple room-only one instead - but now it worths to tune its curve settings a bit more, because otherwise the constant flow is not all bad during the day: it is more comfortable with the radiators not getting too cold.

(yes, my "continental Bosch" boiler also have that eco mode, I'm using it)

glitter-ball commented 3 years ago

Cool! Stick with it. It took me a few weeks to work out the right settings.

I have radiators too and it’s great to have them at the right temperature rather than on/off. House is much more comfortable.

EMS-ESP and HA is really handy to see what’s happening and tune the settings.

Junkers Cerapur Compact ZWB 24. Very interesting, now on version v2.1.1b6 the heating is turned off immediately after the start. An increase in temperature and a command (call boiler heatingactivated on) to turn on the heating does not give a reaction. The most interesting thing is that you can now change the temperature on the boiler itself, but the heating remains inactive.

levran commented 3 years ago

returned the firmware v2.1.0, the heating was immediately activated.

MichaelDvP commented 3 years ago

Indeed very interesting, ems-esp does not send any commands to the boiler on start. Can you provide logs, system info nd values?

at this stage I installed a new firmware and rescanned the devices. As you can see, the heating has turned off.

hmm, I was in a hurry. after 10 seconds it turned out that the heating became active. Now, as before, I cannot influence it using the command call boiler heatingactivated on / call boiler heatingactivated off

it is interesting that if you press reset on esp32, then the heating icon on the boiler also disappears for a couple of seconds.

Boiler: HT3 (DeviceID:0x08, ProductID:95, Version:43.05)

There seems to be something wrong with the beta in device detection. This should be the same as in v2.1.

Service code: Service code number: 0

Seems your boiler uses some other telegrams. Can you please type in terminal watch on 08 and post the output of a minute watching.

Now, as before, I cannot influence it using the command call boiler heatingactivated on / call boiler heatingactivated off

This command does not work on all boilers. For my GB125 the command is accepted by the boiler, but withing a few secondes overwritten by the controller (MC10). Therefore it's a read-only state. Maybe something similar with your system.

This command does not work on all boilers. For my GB125 the command is accepted by the boiler, but withing a few secondes overwritten by the controller (MC10). Therefore it's a read-only state. Maybe something similar with your system.

since I do not have a thermostat, I really hope this command will work.

On my system it's not the thermostat, it's the boiler control panel that overrides any setting of heatingActivated. ( look at this image, the right rotary control set heating on/off and nothing by software can change it). If my thermostat wants to stop heating it sets the flowtemp to zero. I think this should work always.

The 0x18 telegram indeed does not publish a service-code. Is your controlpanel capable to show the service code?

levran commented 3 years ago

there is sample of control panel

I don't understand how to find out.

May be this? "Service function 8b: coding plug number

Just check this code =27

Boiler: HT3 (DeviceID:0x08, ProductID:95, Version:43.05)

There seems to be something wrong with the beta in device detection. This should be the same as in v2.1.

I made a test to simulate your HT3 boiler and gateway and can't reproduce why the name's are switched. Do you get Boiler: HT3 (DeviceID:0x08, ProductID:95, Version:43.05) all the time?

I got Boiler: HT3 (DeviceID:0x08, ProductID:95, Version:43.05) on 2.1.1b6 firmware and Boiler: HT3 (DeviceID:0x08, ProductID:95, Version:43.05) on EMS-ESP version 2.1.0
