Comments

Hello, I would like to submit request for new device: Siemens RDZ100ZB smart thermostat.

I tried it on my own, but partly successful. I am reading basic battery and thermostat properties, but submiting new occupied_heating_setpoint was sometimes successful and sometimes zigbee returns timeout error.

Error change request:

Error 2023-12-10 00:27:49Publish 'set' 'occupied_heating_setpoint' to 'Siemens RDZ100ZB' failed: 'Error: Write 0x0080e1250167790e/1 hvacThermostat({"occupiedHeatingSetpoint":1800}, {"sendWhen":"immediate","timeout":10000,"disableResponse":false,"disableRecovery":false,"disableDefaultResponse":true,"direction":0,"srcEndpoint":null,"reservedBits":0,"manufacturerCode":null,"transactionSequenceNumber":null,"writeUndiv":false}) failed (Timeout - 61017 - 1 - 139 - 513 - 4 after 10000ms)'

These new devices from Siemens look promising. Please keep us updated

For anyone wondering how my convertor works, I am using it with home assistant for about a week with no issues. Errors was in my opinion tied to rapid temperature change I did during testing.

Good to hear! I am planning to buy and use this thermostat with my sonoff zigbee 3.0 usb -e dongle in HA. Did you encounter any problems when pair the device? Also, is there a way to select TPI mode (slow/medium/fast) or desired 2-position via zigbee2mqtt?

I am planning to buy and use this thermostat with my sonoff zigbee 3.0 usb -e dongle in HA - I have same dongle and setup. Did you encounter any problems when pair the device? - Pairing device was without problem. Also, is there a way to select TPI mode (slow/medium/fast) or desired 2-position via zigbee2mqtt? - No, the converter does not cover this yet. My guess is that it uses default TPI slow mode (it is noted in docs as default value).

From docs it is definitely possible to change these settings over zigbee (it is even mandatory, because you can not change these on device by hand), but siemens have it hidden under custom keys in communication, so it is impossible to decifer it without help.

Since there are five modes of operation (Control behavior: 2-Pos 1K, 2-Pos 0.3K, TPI Slow, TPI Medium, TPI fast) they could be enumerated as 0,1,2,3 and 4. The default, TPI Slow, is third in the list (2) which is the value of "ctrlSeqeOfOper" in your trace. Just a wild guess...

Hi, I am using the same model for a month now via HA and it works fine. The only issue that I have is that every about 2 weeks the display becomes unresponsive, while the thermostat operates fine via zigbee. Removing and re-inserting the batteries fixes the display. Have you encountered a similar issue? The firmware version (sw_build_id) is 0.00.04.

[JFFilip]

Hi, no, I do not, but I barely touch the device, mostly change values remotely.
