Thus, we push updates for the purpose of introducing New Features or in order to improve Existing Functionality. We are committed to making our products better! We have made the option to update the firmware of your device (check improvements each version brings below) via a remote update. Learn on how to initiate the update in the [FUOTA section](/mclimate-lorawan-devices/firmware-upgrade-over-the-air-fuota.md) of our documentation. {% endhint %} **Would you like to receive news about new firmware updates for our products?**\ **Subscribe to our newsletter via the link below.** {% embed url="" fullWidth="false" %} ### Firmware version 1.3 **Release date:** \ 04 Aug 2026 * **Bug fixed:** The default [*Overheat recovery threshold temperature*](/mclimate-lorawan-devices/devices/mclimate-16a-dry-switch-16ads/mclimate-16ads-device-communication-protocol/relay-state.md#you-can-set-the-relay-state-after-overheating-protection-recovery-with-the-command) was incorrectly set to 0 and, when updated via radio command, was not saved in the device’s non‑volatile memory. * **Bug fixed:** Reading the [*Relay State After Power‑up*](/mclimate-lorawan-devices/devices/mclimate-16a-dry-switch-16ads/mclimate-16ads-device-communication-protocol/relay-state.md#you-can-set-the-relay-state-after-return-of-power-supply-with-the-command) setting via radio command **0x5F** always returned **0x00**. * **Bug fixed:** The [*LoRaWAN region*](/mclimate-lorawan-devices/devices/mclimate-16a-dry-switch-16ads/mclimate-16ads-device-communication-protocol/network-related-settings.md#get-lorawan-region) read command did not return any response. ### Firmware version 1.2 **Release date:** \ 14 May 2026 * 🆕 NEW [Device-to-device (D2D) radio communication](/mclimate-lorawan-devices/devices/mclimate-16a-dry-switch-16ads/mclimate-16ads-device-communication-protocol/device-to-device-communication-d2d.md#set-d2d-device-credentials) has been implemented. * Added [radio commands to manage D2D communication](/mclimate-lorawan-devices/devices/mclimate-16a-dry-switch-16ads/mclimate-16ads-device-communication-protocol/device-to-device-communication-d2d.md#set-d2d-device-credentials). * Added a [radio command to flip the relay's state](/mclimate-lorawan-devices/devices/mclimate-16a-dry-switch-16ads/mclimate-16ads-device-communication-protocol/relay-state.md#flip-relay-state). * Improved the functionality of device [restart ](/mclimate-lorawan-devices/devices/mclimate-16a-dry-switch-16ads/mclimate-16ads-device-communication-protocol/restart-device.md)command to account for the received downlink type (confirmed or unconfirmed). * Added a random delay of 0–15 seconds for the radio join procedure and keep-alive uplinks. * Improved the [radio watchdog ](/mclimate-lorawan-devices/devices/mclimate-16a-dry-switch-16ads/mclimate-16ads-device-communication-protocol/network-related-settings.md#communication-watch-dog)functionality. ### Firmware version 1.1 **Release date:** \ 20 March 2025 * Fixed bug - the radio does not reset when the button is pressed while the radio is busy. * Fixed bug - the relay turning on for a short time when overheating protection is triggered and the device is restarted. * Fixed bug - incorrect operation of the LED indication when switching between on and off continuous indication mode. * NEW - functionality for relay timer and radio [command](/mclimate-lorawan-devices/devices/mclimate-16a-dry-switch-16ads/mclimate-16ads-device-communication-protocol/relay-state.md#relay-timer-in-milliseconds) for timer setting. * NEW - functionality and radio [command](/mclimate-lorawan-devices/devices/mclimate-16a-dry-switch-16ads/mclimate-16ads-device-communication-protocol/relay-state.md#relay-state-change-reason) to get the reason for changing the relay state. * The default overheat protection trigger limit has been changed from 95°C to 85°C. ### Firmware version 1.0 **Release date:** \ 31 October 2024 * Initial firmware release. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.mclimate.eu/mclimate-lorawan-devices/devices/mclimate-16a-dry-switch-16ads/release-notes.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
