Please note: the Heat Pump Optimizer X only connects to 2.4 GHz Wi-Fi. If your router shows both 2.4 GHz and 5 GHz networks, make sure that your phone is connected to the 2.4 GHz network that the Heat Pump Optimizer X is trying to connect to.
If this is not the case, try the following:
Switch your phone’s Wi-Fi from your home’s 5 GHz Wi-Fi network to the 2.4 GHz network (if possible).
Move to a room farther from the router. The 5 GHz signal weakens over distance, prompting your phone to automatically switch to the 2.4 GHz network.
Access your Wi-Fi router’s settings to either deactivate the 5 GHz network entirely or enable mDNS communication between the 2.4 GHz and 5 GHz networks.
