EMS ESP Console problems

[kempa007]

Hi,

I have just purchased EMS E32 gateway. It works, but when I log in to the console I cant enter boiler, thermostat submenu. Do I need to turn it on somewhere?

There are no submenus in V3 (EMS-ESP32). We are you reading this? Maybe we need to update the documentation!

You can call all commands from the Console or the Web UI. From the console type 'call' and hit or to give you the list of options. Remember you need to be Super User to do this because Telnet has no security built in. So first do a su and type in the default password which is ems-esp-neo unless you have changed it.

Thanks for making it clear. I know it is not openhab forum, but I want to send command to change thermostat temperature. I'm using mosquitto MQTT broker. I tried to run this:

Type number : thermostat_cmd_temp "Thermostat setpoint temp" [commandTopic="ems-esp/thermostat_cmd_temp" ]

But it doesn't work. Do you know how to send command by Openhab MQTT binding? Reading values from EMS bus works like a charm.

See the doc here:
You have to send to topic "thermostat" {"cmd":"seltemp", "data":21,"hc":1}
or activate the single subscriptions in settings and you can write the temperature as number direct to topic "thermostat/hc1/seltemp" or "thermostat/seltemp" if you have choosen main_heatingcircuit.

Great hint :) I'm a bit closer to solve my problem. But after tring:

[commandTopic="ems-esp/thermostat", formatBeforePublish="{"cmd":"seltemp", "data": %s, "hc":"1"}

I am getting an error:
000+21:17:50.903 W 0: [command] Command seltemp on thermostat not found
000+21:17:50.903 E 1: [mqtt] No matching cmd (seltemp)

Some more information about your system will help. Like what thermostat do you have (do a http://ems-esp/api/system)?

If your thermostat does not support Write commands then the command will not work. You can also check by going to the console and typing # show commands

[kempa007]

Yes, forgive me. I think it should, cause I can change termostat temperature from EMS-ESP web panel. This is an output form show commands (my thermostat is Buderus RC310):

thermostat: building building * [hc] comforttemp comfort temperature * commands list all commands [hc] controlmode control mode * datetime date/time * [hc] designtemp design temperature * [hc] ecotemp eco temperature * info list all values [hc] manualtemp manual temperature * [hc] maxflowtemp max flow temperature * minexttemp minimal external temperature * [hc] minflowtemp min flow temperature * [hc] mode mode * [hc] nofrosttemp nofrost temperature * [hc] offsettemp offset temperature * [hc] program program * [hc] roominfluence room influence * [hc] seltemp selected room temperature * [hc] summersetmode set summer mode * [hc] summertemp summer temperature * [hc] tempautotemp temporary room temperature automode * wwcircmode circulation pump frequency * wwmode mode * wwsettemp set temperature * wwsettemplow set low temperature *
So there is seltemp command.

could you still do a http://ems-esp/api/system ?

[kempa007]

Yes of course. Thanks for your time:

thanks! I see the problem. You have multiple Thermostats and the command is going to the wrong one. This was fixed in the dev release but has yet to make it to the stable. You can get the binary from https://github.com/emsesp/EMS-ESP32/releases/tag/latest

and then re-try

sorry and thanks for your patience!

[kempa007]

Okay, I will try, but have you got some tutorial how to upgrade my hardware? I am using E32 gateway form https://bbqkees-electronics.nl/.

[proddy]

You can upgrade from the web interface in a few clicks. See https://bbqkees-electronics.nl/wiki/gateway/firmware-update-and-downgrade.html

[kempa007]

I just upgraded firmware, but the error is still the same:

000+00:04:05.194 W 0: [command] Command seltemp on thermostat not found
000+00:04:05.194 E 1: [mqtt] No matching cmd (seltemp)

maybe this will help a bit more (log level debug)

[kempa007]

I figured it out. It was a problem with formating the command:
this one didnt work:

[commandTopic="ems-esp/thermostat", formatBeforePublish="{"cmd":"seltemp", "data": %s, "hc":"1"}

but this one runs well:

[commandTopic="ems-esp/thermostat", formatBeforePublish="{cmd:"seltemp", data: %s, hc:"1"}

[proddy]

good!
