Dear Sir, I own a Homey Pro 2019 and recently decided to perform a factory reset to organize my device network. After the reset, I re-added all devices, starting with those connected to power (routers with neutral). The powered devices were added without issues, but I encountered difficulties when connecting battery-powered devices. Aqara devices, such as: - motion sensor, - temperature sensor, - two-button remote, during the pairing attempt display a message about starting the pairing process, but after some time, an error appears indicating a timeout and connection interruption. Interestingly, other battery-powered devices, such as the Philips motion sensor or the Aqara water leak sensor, were successfully connected without any issues. Additionally, I noticed that one of the powered devices (router) spontaneously lost connection. I have the impression that when one device loses connectivity, only then can I add another – but in such a case, some other device always stops working. Currently, I have 50 devices connected, but I am still missing about 10 battery-powered devices to complete the network. I was hoping the reset would resolve the previous connectivity issues, which I attributed to the incorrect order of adding devices (at that time, I sometimes added battery-powered ones before the powered ones). Unfortunately, the problem persists and is becoming frustrating. I kindly ask for support in resolving this issue. Is there any procedure or guideline that could help in correctly adding the remaining devices? Thank you in advance for your help ---

The official guidelines can be found here: [https://support.homey.app/hc/en-us/articles/360019239879-Creating-a-stable-Zigbee-network-with-Homey-Pro](https://support.homey.app/hc/en-us/articles/360019239879-Creating-a-stable-Zigbee-network-with-Homey-Pro) Also note that _“Using Zigbee routers, you can create a stable Zigbee network of around 30-40 devices with Homey”_. ---

This is incredibly interesting what you’re saying, because when I bought Homey Pro 2019, they said you could connect up to 255 devices. Now it turns out that it’s only 30-40? ---

I don’t know if it was Athom who ever said that 255 devices was the limit, but if they did, it was probably the marketing department that did that. ---

Do you think buying Homey Pro 2023 will solve my problems? Honestly, I was disappointed with Homey Pro 2019. ---
